    Description

    FiiO BTR15 Portable Hi-Res Bluetooth DAC and Amplifier

    The legend, evolved. The FiiO BTR15 takes everything you loved about the best-selling BTR5 and elevates it to a new level. Featuring a lighter, more ergonomic curved glass body and a massive power upgrade, the BTR15 is the ultimate pocket companion for audiophiles who demand studio-quality sound from their smartphones and laptops.

    Powerful Core, Curved Design

    Dual ESS ES9219MQ DACs

    Experience clarity like never before. The BTR15 employs two high-performance ESS ES9219MQ DAC chips. These chips work in tandem to decode high-resolution audio with remarkably low distortion, supporting MQA decoding and delivering a lush, detailed sound signature.

    Hot-Bent 3D Glass Body

    Inspired by the flagship BTR7, the BTR15 features hot-bent 3D curved glass on both the front and back, seamlessly meeting the aluminum alloy frame. This makes it lighter (only 37.3g) and more comfortable to hold than its predecessor, while the 0.96-inch OLED display provides clear visibility of all your settings.

    Versatility Redefined

    Patented PC / BT / PHONE Switch

    Switching modes has never been easier. The BTR15 features a dedicated three-position toggle switch:

    • PC Mode: Powered via USB, perfect for use as a laptop DAC.

    • BT Mode: Runs on battery for wireless Bluetooth freedom.

    • PHONE Mode: Uses the internal battery to power the DAC while connected via USB-C to your phone, preventing it from draining your smartphone's battery.

    Global Parametric EQ (PEQ)

    Take full control of your sound. Unlike standard EQs, the BTR15’s Global PEQ works across all operating modes (including Bluetooth and USB). Through the proprietary DSP algorithm, you can fine-tune specific frequencies to match your headphones perfectly without sacrificing audio quality.

    Frequently Asked Questions

    Is the BTR15 better than the BTR5?

    Yes. The BTR15 has significantly more power (340mW vs 240mW), a larger 0.96-inch display, a lighter curved body, and the convenient PC/BT/PHONE mode switch which the BTR5 lacks.

    Can I use it for gaming?

    Yes. In "PC Mode" with the XMOS XU316 chip, the BTR15 supports UAC 1.0 (driverless) and UAC 2.0 (high-res), making it compatible with PS5 and Switch for low-latency gaming audio.

    Change modes with just one

    button


    Due to the BTR15's ability to work as a Bluetooth receiver
    and as a USB DAC, we have implemented a PC/BT/PHONE
    mode button on it. With just a click of a button, you can
    quickly switch between the three different modes to match
    your current scenario for listening to high-quality music.














    <h1><br/><br/><br/>Global parametric EQ</h1><h1>Be the master of your music</h1>




    Global parametric EQ

    Be the master of your music

    The BTR15 features a global parametric equalizer (PEQ).
    Through FllO's self-developed PEQ algorithm and user
    interface, in any mode*you can choose the exact
    frequencies to be adjusted along with their gain levels and
    bandwidth- allowing you to fine-tune the sound to exactly
    the way you want it.
    PEQ notes:
    *BT mode PEQ adjustments are implemented through the
    QCC5125 DSP with support for LDAC and other Bluetooth formats
    up to 96kHz/24bit.
    *PC/PHONE mode PEQ adjustments are implemented through the
    XMOS XU316 with support up to PCM 192kHz.
    *PC/PHONE mode PEQ adjustments are implemented through the
    XMOS chip. Enabling or disabling the PEQ, USB will restart and
    disconnect.




    <h1><br/><br/>Dual-core upgrade<br/>Two modes of high-res audio<br/></h1>



    Dual-core upgrade
    Two modes of high-res audio


    The upgrades start from the heart of the BTR15
    specifically the cores that power it. The BTR15
    employs the high-performance combination of the
    Qualcomm QCC5125 Bluetooth chip = XMOS 16-core
    XU316 that supports stable high-res audio playback in
    any mode*, allowing you more ways to immerse
    yourself in the world of high-quality hi-res music.

    Sampling rate notes:
    *BT mode supports LDAC/aptX Adaptive/aptX LL/aptX
    HD/aptX/AAC/SBC and other high-resolution Bluetooth formats
    with sampling rates up to 96kHz;
    *PC/PHONE modes support asynchronous decoding up to
    384kHz/32bit PCM and DSD256.



    <h1><br/><br/><br/><br/><br/>MQA Full Decoder for<br/>master-quality sound</h1>






    MQA Full Decoder for
    master-quality sound


    The BTR15 supports MQA Full Decoder*, which
    means the MQA decoding can be achieved in any
    music app. This allows for high-resolution, master-
    level sound quality in reasonably sized files well-
    suited for your mobile device.

    *Supports up to 384kHz sampling rate






    <h1><br/><br/><br/><br/><br/>Dual curved glass<br/>Dual upgrades to look and grip</h1>






    Dual curved glass
    Dual upgrades to look and grip

    With the BTR15, FllO uses hot-bent curved glass for the first
    time-embedding it on both the front and the rear of the device.
    Not only does this make the device easier to hold, but it also
    gives the BTR15 a more attractive and 3D appearance,
    Together with the aluminum alloy middle frame, they make the
    BTR15 a comfortable device to handle - you won't be able to
    put it down once you pick it up.







    <h1><br/><br/>0.96-inch OLED display<br/>See all the info with just a glance</h1>



    0.96-inch OLED display
    See all the info with just a glance

    Like its bigger brother the BTR7, the BTR15 also features a large
    display - a brilliant 0.96-inch OLED display. This display not only
    allows displaying more information at once, it also allows for larger
    display fonts- making it easier for you to see the device status and
    change various settings. Moreover, it is the rarely seen device that
    supports bilingual languages, Chinese and English, among similar
    products.












    <h1><br/><br/><br/><br/><br/>Dual outputs<br/>Covering all angles<br/></h1>






    Dual outputs
    Covering all angles

    In addition to the standard 3.5mm single-ended headphone
    output, the BTR15 also comes with the widely-used 4.4mm
    balanced headphone output- featuring greater contact
    reliability and durability compared to the 2.5mm balanced
    out. The dual outputs ensure you can use the BTR15 with:listening
    more headphones,for moreremarkable
    experiences.









    <h1><br/><br/><br/>Independent power supply for amp<br/>Explosive power</h1>




    Independent power supply for amp
    Explosive power


    Electricity is the mother of sound. Feiao engineers have carefully
    designed an independent power supply system for DAC ES9219MQ built
    in earmuffs, so that earmuffs no longer share the power supply with DAC
    and the power supply is purer. In addition, the uniquely designed external
    power supply has the characteristics of low noise and high current, which
    increases the balanced output power of BTR15 by 40% to 340mW, and
    can easily meet the needs of portable use.













    <h1><br/><br/>Parallel output, more power</h1>



    Parallel output, more power

    You don't have to use the 4.4mm balanced output to enjoy the benefits of
    increased output power. In order to improve the performance of the BTR15 in
    every aspect, FllO connected the headphone outputs in parallel to also greatly
    increase the output power of the 3.5mm single-ended output to better drive low-
    impedance headphones, allowing you to better unlock their potential.

















    <h1><br/><br/><br/><br/>Comprehensive battery protection<br/>From worry to peace of mind</h1>





    Comprehensive battery protection
    From worry to peace of mind

    In order to alleviate concerns about battery health, FlO engineers
    have implemented a number of software and hardware measures to
