Master of All Trades

The BTR17 showcases FiiO’s expertise in DACs and headphone amps, packing flagship features like a multi-stage audio architecture and precision power supply into a compact design. A versatile powerhouse, it sets a new standard for Bluetooth headphone amps.

A New Era of Bluetooth

The BTR17 features Qualcomm’s flagship QCC5182 chip, supporting Bluetooth LE Audio with a 2.1Mbps bandwidth for CD-level lossless sound via aptX Adaptive. With Bluetooth 5.4 and support for LDAC, aptX Adaptive 96kHz/24bit, and Snapdragon Sound, it delivers an unmatched Bluetooth listening experience.

Patented Desktop Mode

The BTR17 features a dedicated desktop mode switch (D.Mode) and an external power port. In this mode, it can act as a dongle DAC/amp while being powered via USB, protecting its battery and preserving your phone’s charge. With external power, its THX amp utilizes four op-amps in parallel, delivering up to 650mW + 650mW balanced output—203% more power than the BTR7, rivaling desktop amplifiers.

XMOS 16-Core XU316

The flagship XMOS XU316 USB chip offers lower latency, stable transmission, and improved compatibility compared to standard USB controllers. Supporting 768kHz/32bit audio, DSD512 native, and MQA full decoding, it handles virtually any audio stream with ease. Its powerful processing also enables high-definition PEQ for audio up to 192kHz on the BTR17.

Sound Tuning

FiiO’s refined integration of hardware and software delivers user-friendly apps and precise PEQ adjustments. You can fine-tune EQ points, gain, bandwidth, and Q values to customize or correct headphone frequency responses. EQ curves can also be imported, exported, shared, and saved, offering endless possibilities for sound tuning.

Dual Flagship ES9069Q DACs

The BTR17 houses dual ESS ES9069Q DACs with 4th-gen 32-bit HyperStream architecture, combining high performance with low power consumption. This design minimizes digital noise, achieving a 130dB dynamic range and -120dB THD, resulting in a clean audio background and richly musical sound.

Multi-Stage Design

The BTR17 features a three-stage precision power supply with overvoltage protection, DC-DC boost conversion, and high-precision LDO voltage stabilization. Independent power rails for digital, DAC, and analog amplification ensure stable energy delivery for superior sound quality. Packed with mid-to-high-end HiFi player-level signal processing, it uses dual-clock DACs and multi-stage analog audio processing to deliver precise detail and dynamic range, rivaling premium digital audio players.

Additional Features

One Switch
The BTR17 features a convenient PC/BT/PHONE three-position switch which allows it to seamlessly switch between operating modes.

THX AAA 78+ Amp
The BTR17 uses the THX AAA 78+ headphone amp, as in the FiiO KA17 and M23. The 4-channel fully balanced design utilizing 8 op-amps in parallel ensures robust yet controlled power, for clearer and more natural sound.

Comprehensively Protected
Built-in temperature and DC output detection prevents damage to the device and headphones if abnormal conditions are detected.

Press-sable Volume Knob
The exquisite craftsmanship of the press-able knob is evident when pressed or rotated, offering excellent tactile feel and control.

Specially Processed 8-Strand Decoding Cable
Six strands of mono crystalline handles the current transmission, providing abundant power and purer sound. Two strands of mono crystalline silver-plated handles digital transmission, ensuring accurate data transmission with high fidelity.
