BTR17
Portable Bluetooth DAC and Headphone Amplifier

Experience unrivalled audio quality on the go with FiiO BTR17, a portable DAC and headphone amplifier with Bluetooth.
Packed with top technology to take care of decoding, digital to analog conversion, and THX AAA amplification, the BTR17 provides support for premium Bluetooth codecs such as aptX Lossless and LDAC up to 96 kHz. Enjoy your favourite wired headphones and earphones without plugging them into a source device — instead, plug them into the BTR17, then connect wirelessly to your smartphone, tablet, laptop, or other Bluetooth audio source device.
But it's not just about Bluetooth. BTR17 brings together FiiO's years of expertise in developing DACs and headphone amps. Within a compact package, it fits flagship-level features such as a multi-stage audio architecture and precision power supply system comparable to other high-end players and DAC/headphone amp combos.
Enjoy BTR17 as a Bluetooth DAC, a USB DAC with its own internal battery, or plug it in at home for use with your desktop. It is truly a master of all trades designed to become a new standard in its class.
Purchases from Bay Bloor Radio include a 1-Year Warranty from FiiO Canada, with local repair/replacement without the need for international shipping.
Flagship Bluetooth
The BTR17 employs the latest high-performance flagship Qualcomm QCC5181 Bluetooth chipset with Snapdragon Sound Technology, which meets the LE Audio standard with Bluetooth 5.4. It supports various Bluetooth formats, most notably the new aptX Lossless codec. This means the chip is capable of achieving CD-level lossless sound quality over Bluetooth audio, bringing you ever closer to the music with all of its intricate details. You'll also be able to use LDAC, aptX Adaptive, aptX LL, aptX HD, aptX, AAC, and SBC, with sampling rates of up to 96kHz.
Better USB
Not listening over Bluetooth? The XMOS chip employed for USB audio is the flagship XU316, which boasts lower latency, more stable transmission, and better compatibility than typically used USB controllers. Support for 768kHz/32bit audio, DSD512 native, and MQA full decoding means that the chip can handle almost any audio stream that comes its way. The XU316’s ample computing power also enables a high definition parametric equalizer supporting up to 192kHz audio on the BTR17.
Dual Flagship DACs
Inside the BTR17 are two ESS ES9069Q DACs based on the fourth-generation 32-bit HyperStream architecture, achieving high performance while using less power — ideal for a portable battery-powered unit such as this. This architecture helps to further reduce digital noise within the DAC, allowing it to hit 130dB dynamic range and -120dB total harmonic distortion. The result is a richer, musical sound against a cleaner audio background.
The audio architecture is further enhanced as digital signals are deftly handled by the dual-clock system. LPF preamplification and multi-stage analog audio processing ensure details and the dynamic range within audio signals are precisely restored, comparable to premium digital audio players.
THX AAA headphone amplifier
The BTR17 uses the THX AAA 78+ headphone amp, previously found in the much larger FiiO M23 digital audio player. The four-channel fully balanced design utilizes 8 op-amps in parallel to ensure robust yet controlled power, for clearer and more natural sound.
When the POWER IN port is connected to USB power and desktop mode is activated, the BTR 17's THX headphone amp will use four op-amps in parallel for current amplification to fully unleash its potential. The result is a balanced output power up to an astonishing 650mW+650mW, approaching some desktop headphone amplifiers.
Desktop Mode
The BTR 17 features a dedicated D.Mode (desktop mode) switch along with a port to connect an external independent power supply. When in desktop mode, if you connect the BTR 17 to a phone as a dongle DAC and headphone amplifier. You can then also choose to connect an external power supply to the BTR17 via its dedicated power port; doing so means it is capable of more powerful audio output for harder-to-drive headphones, without consuming the connected phone’s battery.
Three battery modes
On the BTR17 is a convenient three-position switch which allows you to seamlessly change operating modes. Switching modes allows the BTR17 to optimize its power supply status according to the device connected, making it flexible enough for various use cases.
- PC: The device is completely powered by the computer.
- BT (Bluetooth DAC and amp): The device is powered by the internal battery, and when connected to USB can be used for charging and power supply.
- PHONE (phone dongle): The device’s internal battery participates in supplying power, reducing the battery consumed from the connected phone.

FiiO has worked constantly to deeply integrate software and hardware in order to create user-friendly mobile apps and web interfaces. The continuously refined proprietary PEQ adjustment algorithms allow you to finely adjust EQ frequency points, gain, bandwidth, and Q value to your liking. This fully lets you simulate or aujust the frequency response curve of various headphones. Additionally, you can import, export, share, and save EQ curves.
In addition to the FiiO Control smartphone app, EQ setup can also be accessed via a browser-based interface. The side of the BTR17 features a dedicated EQ shortcut key, which you can press to quickly select your desired EQ settings.
Protection
Built-in temperature and DC output detection prevents damage to the device and headphones if abnormal conditions are detected to ensure safer usage. A volume limit option also helps to protect your hearing.
Flagship design
It's all in the details. BTR17 features a sturdy aluminum alloy body, with a back cover made of fully-bonded raw leather. When combined with the two-section beveled front panel design, this material helps provide a comfortable grip. The volume knob of the BTR17 features a double-sided 3D engraved design; its craftsmanship is evident when pressed and rotated, offering an excellent tactile feel. The 1.3-inch IPS display is paired with a colourful new interface, allowing key playback information to be gained at a glance.
Leatherette case
The BTR17 includes a colour-matched leatherette case, along with a braided USB-C to USB-C OTG cable for data transfer — perfect for when you're using BTR17 as a USB DAC.
