    (June 24, 2014)
    Before TJOFLAT, JORDAN and KRAVITCH, Circuit Judges.
    PER CURIAM:
    Case: 13-13157     Date Filed: 06/24/2014   Page: 2 of 21
    Nemias Cintora-Gonzalez and Jorge Armando-Reyes challenge their
    convictions and total sentences for drug, firearm, and counterfeiting offenses. For
    the reasons that follow, we affirm.
    I.
    Cintora-Gonzalez and Armando-Reyes were charged, along with several
    others, with conspiracy to distribute at least 500 grams of methamphetamine and at
    least 5 kilograms of cocaine, in violation of 21 U.S.C. § 846 (Count 1); possession
    with intent to distribute cocaine, in violation of 21 U.S.C. § 841(a)(1)(A) (Count
    2); possession with intent to distribute methamphetamine, in violation of 21 U.S.C.
    § 841(a)(1)(A) (Count 3); possession of a firearm in furtherance of a drug-
    trafficking crime, in violation of 18 U.S.C. § 924(c)(1)(B)(i) (Count 4); possession
    of a firearm by an illegal alien, in violation of 18 U.S.C. §§ 922(g)(5), 924(a)(2)
    (Count 6); and possession of counterfeit federal reserve notes, in violation of 18
    U.S.C. § 472 (Count 8). They were convicted of all the above counts, with the
    jury specifically finding that the amount of drugs in Count 1 was at least 500 grams
    of methamphetamine and at least 5 kilograms of cocaine.
    At a joint sentencing, the district court found that Cintora-Gonzalez’s base
    offense level for the drug offenses was 34 given the amount of drugs involved, that
    he served as the leader of the charged conspiracy, and that he maintained a
    premises for distributing drugs. With respect to the § 922(g) offense, the court
    2
    Case: 13-13157       Date Filed: 06/24/2014       Page: 3 of 21
    found that he possessed 17 firearms. His corresponding guidelines range was 292
    to 365 months’ imprisonment for the drug offenses, the § 922(g) offense, and the
    counterfeiting offense. Count 4, the § 924(c) offense, carried a consecutive
    statutory mandatory minimum sentence of 60 months’ imprisonment. The court
    sentenced him to a total sentence of 352 months, which resulted from a sentence at
    the low end of the guidelines range plus a mandatory 60 month term on Count 4.
    The court sentenced Armando-Reyes to a 211-month total sentence based on a
    low-end guideline sentence of 151 months because Armando-Reyes was
    responsible for a lesser amount of drugs, he did not maintain the premises for drug
    distribution, and he did not qualify as a leader of the conspiracy, plus a mandatory
    60 month term on Count 4.
    The defendants now appeal. Specifically, Cintora-Gonzalez challenges the
    admission of certain testimony as prejudicial and his sentence as improperly
    calculated for several reasons. Armando-Reyes challenges the admission of voice
    identification evidence and the calculation of his sentence. 1 We address each
    defendant’s arguments in turn.
    II.
    A. Cintora-Gonzalez
    1  Armando-Reyes indicated in his brief that he was adopting Cintora-Gonzalez’s brief. But
    Armando-Reyes was not subject to the enhancement for maintaining a premises or leadership of
    the conspiracy, and the district court determined he was responsible for a lesser amount of drugs.
    Thus, it is unclear exactly what arguments he intended to adopt.
    3
    Case: 13-13157      Date Filed: 06/24/2014   Page: 4 of 21
    1. Admission of testimony
    Cintora-Gonzalez argues that the district court erred in admitting a law
    enforcement agent’s testimony regarding a series of intercepted calls in which
    Cintora-Gonzalez allegedly made serious threats to an individual named “La
    Torta,” who owed him a drug debt. He maintains that the testimony was unduly
    prejudicial and, therefore, inadmissible under Fed. R. Evid. 403.
    We review the district court’s evidentiary rulings for an abuse of discretion.
    United States v. Brown, 
    415 F.3d 1257
    , 1264-65 (11th Cir. 2005). An abuse of
    discretion can occur where the district court applies the wrong law, follows the
    wrong procedure, bases its decision on clearly erroneous facts, or commits a clear
    error in judgment. 
    Id. at 1266.
    Evidence is admissible if relevant, and evidence is relevant if it has any
    tendency to prove or disprove a fact of consequence. Fed. R. Evid. 401, 402. A
    district court may exclude relevant evidence under Rule 403 if “its probative value
    is substantially outweighed by a danger of . . . unfair prejudice, confusing the
    issues, misleading the jury, undue delay, wasting of time, or needlessly presenting
    cumulative evidence.” Fed. R. Evid. 403. Relevant evidence is often inherently
    prejudicial, so the rule “permits exclusion only when unfair prejudice substantially
    outweighs probative value.” United States v. Merrill, 
    513 F.3d 1293
    , 1301 (11th
    Cir. 2008) (quotation omitted). Thus, we have cautioned that Rule 403 “is an
    4
    Case: 13-13157     Date Filed: 06/24/2014   Page: 5 of 21
    extraordinary remedy which the district court should invoke sparingly, and the
    balance should be struck in favor of admissibility.” United States v. Lopez, 
    649 F.3d 1222
    , 1247 (11th Cir. 2011).
    On review, we conclude that the district court did not abuse its discretion in
    admitting the agent’s testimony. Cintora-Gonzalez’s drug-debt-related threats to
    La Torta evidenced the existence of the charged drug conspiracy, which Cintora-
    Gonzalez admits, and the extent of the conspiracy, which he continues to dispute.
    In other words, the threats had a tendency to prove, albeit indirectly, the large drug
    quantities charged in the indictment. Moreover, the imminent nature of the threats
    led agents to end their investigation quickly, before the arrival of some of the drugs
    discussed in the intercepted calls. As such, the government had to rely on the calls
    to establish the scope of the conspiracy. The testimony concerning the threats
    against La Torta thus completed the story and explained why the investigation
    ended abruptly.
    Although the evidence of his threats may have proved prejudicial to Cintora-
    Gonzalez’s defense, that is often the case with relevant evidence. See 
    Merrill, 513 F.3d at 1301
    . Cintora-Gonzalez has not shown that the risk of misleading the jury
    was so great that the court abused its discretion by admitting the testimony. See
    id.; Fed. R. Evid. 403.
    2. Sentencing
    5
    Case: 13-13157      Date Filed: 06/24/2014    Page: 6 of 21
    We review the district court’s interpretation of the Sentencing Guidelines de
    novo and accept its factual findings unless clearly erroneous. United States v.
    Jordi, 
    418 F.3d 1212
    , 1214 (11th Cir. 2005). We will not reverse a sentencing
    determination if it proved harmless. United States v. Gallegos-Aguero, 
    409 F.3d 1274
    , 1276 (11th Cir. 2005). An error is harmless if, “viewing the proceedings in
    their entirety, a court determines that the error did not affect the [sentence], or had
    but very slight effect.” United States v. Hornaday, 
    392 F.3d 1306
    , 1315 (11th Cir.
    2004) (quotations and citation omitted). When a defendant fails to state clearly the
    grounds for an objection, however, his objection is reviewed only for plain error.
    United States v. Zinn, 
    321 F.3d 1084
    , 1087 (11th Cir. 2003). Plain error exists
    when: (1) there is an error, (2) that is plain, (3) that seriously affects a defendant’s
    substantial rights, and (4) seriously affects the fairness, integrity, or public
    reputation of judicial proceedings. United States v. Acevedo, 
    285 F.3d 1010
    , 1012
    (11th Cir. 2002).
    a. Quantity of drugs
    Cintora-Gonzalez challenges the court’s determination of the drug quantity
    for which he was responsible and its alleged failure to make particularized
    findings. For sentencing purposes, the government bears the burden of
    establishing drug quantity by a preponderance of the evidence. United States v.
    Rodriguez, 
    398 F.3d 1291
    , 1296 (11th Cir. 2005). The district court must ensure
    6
    Case: 13-13157     Date Filed: 06/24/2014    Page: 7 of 21
    that the government carries this burden by presenting reliable and specific
    evidence. United States v. Lawrence, 
    47 F.3d 1559
    , 1566 (11th Cir. 1995). Where
    there is no drug seizure, or the amount seized does not reflect the extent of the
    offense, the court should approximate the drug quantity. United States v. Frazier,
    
    89 F.3d 1501
    , 1506 (11th Cir. 1996). In estimating the drug quantity attributable
    to the defendant, the court’s determination “may be based on fair, accurate, and
    conservative estimates of the quantity of drugs attributable to a defendant, . . . [but
    it] cannot be based on calculations of drug quantities that are merely speculative.”
    United States v. Zapata, 
    139 F.3d 1355
    , 1359 (11th Cir. 1998).
    The Sentencing Guidelines create differing base offense levels for drug
    offenses depending on the quantity of drugs involved. See U.S.S.G. § 2D1.1(c).
    When different types of drugs are involved, the court converts each of the drugs to
    its marijuana equivalent and adds the quantities to obtain a single offense level for
    a defendant. 
    Id. § 2D1.1,
    comment. (n.10(B)). Under the 2012 Drug Quantity
    Table applied in this case, a base offense level of 34 corresponded to offenses
    involving at least 3,000 kilograms, but less than 10,000 kilograms, of marijuana.
    
    Id. § 2D1.1(c)(3).
    At sentencing, defense counsel discussed the amount of drugs listed in the
    presentence investigation report (PSI), conceding some amounts and challenging
    others. The government noted that the jury had specifically found that Cintora-
    7
    Case: 13-13157        Date Filed: 06/24/2014       Page: 8 of 21
    Gonzalez was responsible for at least 500 grams of methamphetamine and 5
    kilograms of cocaine, which corresponded to a level 32 in the Drug Table. The
    court considered the amounts Cintora-Gonzalez conceded distributing, about 1,559
    kilograms of marijuana equivalency, and the amounts discussed in various
    intercepted phone calls. Specifically, the court relied on: (i) a stipulated recorded
    phone call from October 29, 2011, in which Cintora-Gonzalez discussed the sale of
    5 kilograms of cocaine (1,000 kilograms of marijuana equivalency); and
    (ii) evidence of an October 10, 2011 phone call, wherein Cintora-Gonzalez agreed
    to deliver a half pound of methamphetamine (453.6 kilograms of marijuana
    equivalency). Although the court agreed with the defense that certain amounts
    were not supported by the evidence, the court found that there was reliable
    evidence to bring the amount over 3,000 kilograms and an offense level of 34.
    U.S.S.G. § 2D1.1(c)(3). Because the district court relied on specific evidence of
    the attributable drug quantities involved in the offense conduct—including
    admissions by Cintora-Gonzalez—it did not clearly err in assigning him a base
    offense level of 34. See 
    Lawrence, 47 F.3d at 1566
    .
    Moreover, we see no plain error in the manner in which the district court
    determined the drug quantity. 2 The court meticulously reviewed, and made
    findings with respect to, each of the discrete and particularized drug quantity
    2   Cintora-Gonzalez raises this argument for the first time on appeal.
    8
    Case: 13-13157     Date Filed: 06/24/2014   Page: 9 of 21
    allegations contained in the PSI. See 
    Acevedo, 285 F.3d at 1012
    . For these
    reasons, we affirm the district court’s determination of the drug quantity.
    b. Maintaining a premises
    Next, Cintora-Gonzalez challenges the district court’s finding that he used
    his apartment for drug manufacturing and distribution. Section 2D1.1(b)(12) of the
    Guidelines calls for a two-level enhancement “[i]f the defendant maintained a
    premises for the purpose of manufacturing or distributing a controlled substance,”
    including storage of a controlled substance for the purposes of distribution.
    U.S.S.G. § 2D1.1(b)(12) & comment. (n.17). To determine whether the
    enhancement is applicable, the court should consider “whether the defendant held a
    possessory interest in [] the premises and [] the extent to which the defendant
    controlled access to, or activities at, the premises.” 
    Id. § 2D1.1,
    comment. (n.17).
    Manufacturing or distributing a controlled substance need not be the
    sole purpose for which the premises was maintained, but must be one
    of the defendant’s primary or principal uses for the premises, rather
    than one of the defendant’s incidental or collateral uses for the
    premises. In making this determination, the court should consider how
    frequently the premises was used by the defendant for manufacturing
    or distributing a controlled substance and how frequently the premises
    was used by the defendant for lawful purposes.
    
    Id. Few circuits
    have addressed this guideline, and we have done so only in a
    single unpublished opinion. United States v. Vega, 500 F. App’x 889, 891 (11th
    Cir. 2012) (unpublished) (concluding that the district court did not plainly err in
    9
    Case: 13-13157     Date Filed: 06/24/2014   Page: 10 of 21
    applying the enhancement where the defendant sold cocaine from his home on
    multiple occasions). We thus turn to the reasoning of our sister circuits.
    The Eighth Circuit considered the application of § 2D1.1(b)(12) to a
    premises that served both as the defendants’ home and a stash house. United
    States v. Miller, 
    698 F.3d 699
    , 706-07 (8th Cir. 2012). There, the court looked at
    numerous factors, such as quantities of drugs involved, storage of “tools of the
    trade,” maintenance of business records, and customer interactions, to determine
    whether the principal use of the residence was drug distribution. The court had
    little difficulty applying the enhancement to Mr. Miller, the primary drug trafficker
    involved. But as to his wife, the court found the enhancement applicable as well,
    despite her more limited role in the distribution, because she was specifically
    involved in at least three transactions at the home, she used her son to deliver drugs
    to one of the buyers, and she collected payment for drugs on several occasions.
    Moreover, the court determined that under 21 U.S.C. § 856 and § 2D1.1(b)(12),
    Congress intended to deter the use of primary residences as stash houses. In light
    of all of these factors, the court found that the enhancement would apply to a
    defendant who used her primary residence to distribute drugs. 
    Id. at 705-07.
    Relying on Miller, the Seventh Circuit considered and applied the
    enhancement to a defendant who sold drugs out of his home. See United States v.
    Flores-Olague, 
    717 F.3d 526
    , 531-32 (7th Cir.), cert. denied, 
    134 S. Ct. 211
    10
    Case: 13-13157      Date Filed: 06/24/2014       Page: 11 of 21
    (2013).3 The court explained that a defendant “maintained” a premises for drug
    distribution if “he owns or rents premises, or exercises control over them, and for a
    sustained period of time, uses those premises to manufacture, store, or sell drugs,
    or directs others to those premises to obtain drugs.” 
    Id. at 532
    (citing United States
    v. Acosta, 
    534 F.3d 574
    , 591 (7th Cir. 2008)). The court also considered the
    number of drug transactions that occurred on the premises. Because the defendant
    in Flores-Olague had stored cocaine on the premises for several years, sold it to at
    least ten regular customers, and had firearms in the home, the court concluded that
    the enhancement applied.
    The Sixth Circuit upheld the application of § 2D1.1(b)(12) where the
    defendant had both a possessory interest in the residence and controlled the access
    to the home. See United States v. Johnson, 
    737 F.3d 444
    , 447 (6th Cir. 2013). In
    reaching this conclusion, the Sixth Circuit explained that “[T]he more
    characteristics of a business that are present” in the home—such as “tools of the
    trade (e.g., laboratory equipment, scales, guns and ammunition to protect the
    inventory and profits),” “profits,” including large quantities of cash, and “multiple
    employees or customers”—“the more likely it is that the property is being used ‘for
    3 The Seventh Circuit first addressed § 2D1.1(b)(12) in United States v. Sanchez, 
    710 F.3d 724
    (7th Cir. 2013), vacated by, 
    134 S. Ct. 146
    (2013). Because Sanchez has been vacated, albeit on
    other grounds, we rely on the analysis in Flores-Olague.
    11
    Case: 13-13157     Date Filed: 06/24/2014   Page: 12 of 21
    the purpose of’ [prohibited] drug activities.” 
    Id. at 447-48
    (quoting United States
    v. Verners, 
    53 F.3d 291
    , 295-97 (10th Cir. 1995) (discussing 21 U.S.C. § 856)).
    Relying on this persuasive authority, we conclude that the district court
    properly applied § 2D1.1(b)(12) to Cintora-Gonzalez’s guidelines calculations.
    The evidence at trial showed that Cintora-Gonzalez used his apartment for the
    purpose of manufacturing or distributing drugs. Cintora-Gonzalez concedes his
    proprietary interest in the premises. And the evidence showed Cintora-Gonzalez
    controlled access to and activities at the apartment.
    Cintora-Gonzalez’s former girlfriend, Brenda Perez, testified that she leased
    the apartment on his behalf. Additionally, Perez observed drugs in the apartment
    “[e]very time” she visited; she observed Cintora-Gonzalez chop up and mix a
    block of cocaine in the kitchen; there were boxes of baggies in the apartment; and
    Cintora-Gonzalez “always” had a gun in the bedroom. Perez’s observations were
    consistent with the drugs, multiple firearms, ammunition, plastic baggies, digital
    scale, acetone, and counterfeit currency recovered by law enforcement agents after
    they searched the apartment. The presence of these “tools of the trade” supports
    the district court’s conclusion that Cintora-Gonzalez maintained this residence for
    the purpose of drug distribution. Additionally, the evidence showed that Cintora-
    Gonzalez directed others to weigh and distribute drugs when he was out. Although
    12
    Case: 13-13157      Date Filed: 06/24/2014     Page: 13 of 21
    we do not know the number of transactions that occurred at the apartment, under
    these facts, we conclude that the application of § 2D1.1(b)(12) was proper.
    c. Number of firearms
    Cintora-Gonzalez also challenges the district court’s finding that his
    § 922(g) offense involved between 8 and 24 firearms because there was no
    evidence he knew of the guns in his codefendant’s car. He concedes there were
    five firearms involved, and thus a two-level increase would be appropriate.
    Under § 2K2.1(b)(1), a four-level increase applies if an offense involved 8 to
    24 firearms, and a two-level increase applies if an offense involved 3 to 7 firearms.
    U.S.S.G. § 2K2.1(b)(1)(A), (B). “[O]nly those firearms that were unlawfully
    sought to be obtained, unlawfully possessed, or unlawfully distributed” are to be
    counted under § 2K2.1(b)(1). 
    Id. § 2K2.1,
    comment. (n.5).
    In this instance, the district court did not clearly err in its application of the
    § 2K2.1(b)(1)(B) enhancement with respect to his firearm conviction. Cintora-
    Gonzalez does not dispute that the title and the keys to the car in which the
    additional firearms were discovered were found in his apartment, or that the
    vehicle itself was located in the parking lot. But even if the court erred in this
    respect, any such error was harmless because Cintora-Gonzalez’s combined total
    guideline range was determined by the offense level corresponding to the drug-
    trafficking offenses, not his firearm conviction. Thus, any reduction in the
    13
    Case: 13-13157     Date Filed: 06/24/2014    Page: 14 of 21
    guideline range applicable to the firearm offense would prove inconsequential. See
    
    Hornaday, 392 F.3d at 1315
    .
    d. Acceptance of responsibility
    Next, Cintora-Gonzalez challenges the district court’s decision not to award
    any reduction for acceptance of responsibility under § 3E1.1. We review a denial
    of a reduction of sentence for an acceptance of responsibility for clear error.
    United States v. Knight, 
    562 F.3d 1314
    , 1322 (11th Cir. 2009). “Because
    demonstration of whether or not the defendant has personally accepted
    responsibility for his criminal conduct requires a consideration of both objective
    factors and subjective considerations of the defendant’s demeanor and sincerity,
    the district court’s determination will not be overturned unless it is without
    foundation.” United States v. Castillo-Valencia, 
    917 F.2d 494
    , 500 (11th Cir.
    1990).
    Section 3E1.1 provides that the defendant’s offense level should be
    decreased by two points if he “clearly demonstrates acceptance of responsibility
    for his offense.” U.S.S.G § 3E1.1(a). But the commentary to § 3E1.1 explains
    that the adjustment “is not intended to apply to a defendant who puts the
    government to its burden of proof at trial by denying the essential factual elements
    of guilt, is convicted, and only then admits guilt and expresses remorse.” 
    Id. § 3E1.1,
    comment. (n.2). In determining whether a defendant has accepted
    14
    Case: 13-13157     Date Filed: 06/24/2014   Page: 15 of 21
    responsibility under § 3E1.1, the district court may not refuse to find an acceptance
    of responsibility per se simply because the defendant has elected to go to trial.
    
    Castillo-Valencia, 917 F.2d at 500
    . On the other hand, “the entry of a not guilty
    plea and insistence upon a trial are factors that may be considered in deciding
    whether or not a defendant has in fact accepted responsibility for wrongful
    conduct.” 
    Id. at 501.
    Ultimately, § 3E1.1 “is intended to reward those defendants
    who affirmatively acknowledge their crimes and express genuine remorse for the
    harm caused by their actions.” United States v. Carroll, 
    6 F.3d 735
    , 740 (11th Cir.
    1993).
    Generally, a defendant who pleads guilty but contests the drug quantity is
    not entitled to a reduction under § 3E1.1, and Cintora-Gonzalez has pointed to no
    authority otherwise. See, e.g., United States v. Garrasteguy, 
    559 F.3d 34
    , 39-40
    (1st Cir. 2009) (concluding that the defendant was not entitled to a reduction under
    § 3E1.1 where the defendant went to trial to contest the amount of drugs for which
    he was responsible); United States v. Acosta, 
    534 F.3d 574
    , 580 (7th Cir. 2008)
    (denying an acceptance-of-responsibility reduction where defendant pleaded guilty
    but challenged certain factual assertions in PSI); United States v. Annis, 
    446 F.3d 852
    , 857-58 (8th Cir. 2006) (denying acceptance-of-responsibility reduction where
    defendant pleaded guilty but refused to admit to any drug quantity and challenged
    reliability of prior statement to authorities).

    Case: 13-13157     Date Filed: 06/24/2014    Page: 16 of 21
    Therefore, we conclude that the district court did not clearly err in refusing
    to award Cintora-Gonzalez a reduction for acceptance of responsibility under
    § 3E1.1(a). Although his decision to proceed to trial did not preclude the
    adjustment, see 
    Castillo-Valencia, 917 F.2d at 500
    , this is not one of the “rare
    situations” in which the reduction is still applicable, see § 3E1.1, comment. (n.2).
    Cintora-Gonzalez did not go to trial to challenge the constitutionality of the statute
    under which he was charged. Rather, he contested factual allegations of the
    offense conduct.
    Moreover, the court did not rely solely on the fact that he went to trial in
    denying the reduction. The court also noted the lack of documentation related to
    the purported plea negotiations or a written statement in which he formally
    accepted responsibility for the offense conduct. Although Cintora-Gonzalez
    conceded his guilt, the record in this case appears to lack any indication that he
    was genuinely remorseful for his conduct. Accordingly, the court properly denied
    the reduction.
    e. Reasonableness
    In his last argument on appeal, Cintora-Gonzalez contests the substantive
    reasonableness of his 292-month sentence. We review the substantive
    reasonableness of a sentence for abuse of discretion. Gall v. United States, 
    552 U.S. 38
    , 51 (2007).
    16
    Case: 13-13157     Date Filed: 06/24/2014   Page: 17 of 21
    “The review for substantive unreasonableness involves examining the
    totality of the circumstances, including an inquiry into whether the statutory factors
    in § 3553(a) support the sentence in question.” United States v. Gonzalez, 
    550 F.3d 1319
    , 1324 (11th Cir. 2008). The court must consider several factors,
    including the nature and circumstances of the offense, the history and
    characteristics of the defendant, the need to protect the public from further crimes
    of the defendant, the applicable guideline range, and the need to avoid unwarranted
    sentencing disparities between similarly situated defendants. See 18 U.S.C. §
    3553(a). Notably, the “weight to be accorded any given § 3553(a) factor is a
    matter committed to the sound discretion of the district court.” United States v.
    Clay, 
    483 F.3d 739
    , 743 (11th Cir. 2007) (quotations omitted).
    Although we do not automatically presume that a sentence within the
    guidelines range is reasonable, we ordinarily expect that to be the case. United
    States v. Hunt, 
    526 F.3d 739
    , 746 (11th Cir. 2008). A sentence well below the
    statutory maximum sentence also signals reasonableness. See 
    Gonzalez, 550 F.3d at 1324
    . Moreover, we have held that a defendant’s sentence was reasonable in
    light of the command to avoid unwarranted sentencing disparities where, due to a
    defendant’s leadership role, he received a sentence greater than the sentences of his
    codefendants. See, e.g., United States v. Thomas, 
    446 F.3d 1348
    , 1350, 1357 (11th
    Cir. 2006) (holding that the defendant’s 121-month sentence was reasonable even
    17
    Case: 13-13157      Date Filed: 06/24/2014    Page: 18 of 21
    though his codefendants’ sentences ranged from 41 to 53 months’ imprisonment
    because the defendant had coordinated the offense). Ultimately, we will vacate a
    sentence only if “left with the definite and firm conviction that the district court
    committed a clear error of judgment in weighing the § 3553(a) factors by arriving
    at a sentence that lies outside the range of reasonable sentences dictated by the
    facts of the case.” United States v. Irey, 
    612 F.3d 1160
    , 1190 (11th Cir. 2010) (en
    banc) (quotation omitted). “[T]he party who challenges the sentence bears the
    burden of establishing that the sentence is unreasonable in the light of both [the]
    record and the factors in section 3553(a).” United States v. Talley, 
    431 F.3d 784
    ,
    788 (11th Cir. 2005).
    Cintora-Gonzalez has not met his burden. Cintora-Gonzalez’s sentence on
    the drug offenses fell within the guideline range and well below the statutory
    maximum sentence of life imprisonment as to the conspiracy count, both of which
    signal reasonableness. See 21 U.S.C. § 841(b)(1)(A); 
    Hunt, 526 F.3d at 746
    ;
    
    Gonzalez, 550 F.3d at 1324
    . Moreover, his offense conduct included a leadership
    role and threats of personal injury in a heavily armed conspiracy involving large
    amounts of drugs. The dangerousness of that conduct and the public’s interest in
    safety support the court’s sentencing determination. And although Cintora-
    Gonzalez’s co-conspirators received lighter sentences, his leadership role in the
    conspiracy warranted the disparity. See 
    Thomas, 446 F.3d at 1350
    , 1357.
    18
    Case: 13-13157       Date Filed: 06/24/2014      Page: 19 of 21
    Cintora-Gonzalez points in part to his clean criminal history as a factor
    weighing in favor of a lighter sentence, but even though the history of the
    defendant is certainly a consideration, the court also considered the guideline
    range, the nature and circumstances of the offense, and the need to protect the
    public from further crimes. See 18 U.S.C. § 3553(a). Under these facts, Cintora-
    Gonzalez cannot show his sentence is substantively unreasonable.
    B. Armando-Reyes
    1. Voice identification
    Armando-Reyes first challenges the district court’s admission of testimony
    from the government’s voice expert. Generally, we review evidentiary rulings for
    an abuse of discretion. United States v. Henderson, 
    409 F.3d 1293
    , 1297 (11th Cir.
    2005). When a defendant fails to make an objection or argument in the district
    court, however, review is limited to plain error.4 See United States v. Duncan, 
    381 F.3d 1070
    , 1073 (11th Cir. 2004).
    Voice identification testimony can be admitted only after it is determined
    sufficient evidence supports a finding that “the item is what the proponent claims it
    is.” Fed. R. Evid. 901(a). A speaker’s voice may be identified by opinion
    testimony “based on hearing the voice at any time under circumstances that
    4 Although Armando-Reyes objected at trial to the testimony as improper expert testimony, he
    did not challenge the evidence on the ground raised on appeal. Thus, he has abandoned the
    arguments made in the district court, Holland v. Gee, 
    677 F.3d 1047
    , 1066 (11th Cir. 2012), and
    we review his new arguments for plain error.
    19
    Case: 13-13157     Date Filed: 06/24/2014    Page: 20 of 21
    connect it with the alleged speaker.” 
    Id. 901(b)(5). “Once
    a witness establishes
    familiarity with an identified voice, it is up to the jury to determine the weight to
    place on the witness’s voice identification.” Brown v. City of Hialeah, 
    30 F.3d 1433
    , 1437 (11th Cir. 1994). Credibility determinations will not be disturbed on
    appeal unless the testimony is “incredible as a matter of law,” meaning that it
    relates to “facts that the witness could not have possibly observed or events that
    could not have occurred under the laws of nature.” United States v. Flores, 
    572 F.3d 1254
    , 1263 (11th Cir. 2009).
    Here, the district court did not err, plainly or otherwise, in admitting the
    voice-identification testimony. Although Armando-Reyes argues to the contrary,
    the record of the expert’s testimony shows that she familiarized herself with his
    voice through a phone call with him while he was in federal custody awaiting trial.
    Rule 901(b)(5) requires no more foundation than that. See Fed. R. Evid. 901(b)(5).
    Moreover, it does not matter that the expert could not specifically identify which of
    the 20 to 30 recorded calls she used to voice-identify him, because, importantly,
    she was able to voice-identify him in each of the recorded calls introduced into
    evidence. With a proper foundation in place under Rule 901(b)(5), it then fell to
    the jury to determine the credibility of her identification testimony, 
    Brown, 30 F.3d at 1437
    , and, there being nothing “incredible” in her testimony, the jury’s
    determination in that regard will not be disturbed, 
    Flores, 572 F.3d at 1263
    .

    2. Sentencing
    Armando-Reyes argues, like Cintora-Gonzalez, that the district court clearly
    erred in refusing to award him a § 3E1.1 reduction. We conclude the court
    properly denied the reduction for the reasons discussed previously.
    III.
    For the above reasons, we affirm the convictions and sentences for both
    Cintora-Gonzalez and Armando-Reyes.
    AFFIRMED.
