About this item

Product details

The FiiO BTR17 in Black is a portable Bluetooth DAC and headphone amplifier that also works as a high-resolution USB DAC. It uses a Qualcomm QCC5181 Bluetooth 5.4 chip supporting LDAC, aptX Lossless, aptX Adaptive, aptX HD, aptX, AAC, and SBC. Decoding is handled by two ESS ES9069Q DACs, and an XMOS 16-core XU316 USB controller supports PCM up to 768kHz/32-bit, native DSD512, and full MQA decoding in USB DAC mode. A four-channel fully balanced THX AAA 78+ amplifier stage drives the 3.5mm single-ended and 4.4mm balanced outputs. When the POWER IN port is connected to USB power and Desktop Mode is enabled, balanced output reaches 650mW + 650mW at 32 ohms and single-ended output reaches 280mW + 280mW at 32 ohms. A physical volume knob, a 1.3-inch 240 x 240 color IPS display, and a 10-band parametric EQ through the FiiO Control app provide control, and a built-in microphone supports hands-free calls. Battery life is about 8 hours using LDAC with a charging time of 2 hours or less. It measures about 16.3 x 41.2 x 86.6 mm and weighs about 73.4g, with an aluminum alloy body and leather back cover.

Equipped with Qualcomm's new-generation flagship Bluetooth chip, the QCC5181, the UTWS5 2025 supports Bluetooth 5.4, complies with the LE Audio standard, and offers a bandwidth transmission capability of up to 2.1Mbps. It also supports the Lossless specification in the aptX Adaptive system, as well as audio codecs like LDAC and aptX Adaptive at 96kHz/24bit.
When enabling desktop mode and using the BTR17 to connect to a smartphone as a tail DAC/amp, you can connect the dedicated power input to an adapter. In this case, the battery will be fully powered by USB, preventing overcharging and overdischarging. The device also delivers a powerful 650mW output capability while not consuming the smartphone's battery.
With lower latency, more stable transmission, and better compatibility than regular USB chips, the device supports 768kHz/32bit, hardware decoding for DSD512, and full MQA decoding. It also features PEQ developed on this platform, allowing adjustments via both the app and web interface, with support for high-definition PEQ at a sampling rate of up to 192kHz.
The BTR17 is equipped with two ESS flagship dual-channel DACs, the ES9069Q, based on the fourth-generation 32-bit HyperStream architecture. This allows for enhanced performance and lower power consumption. Additionally, it further reduces digital noise within the DAC, achieving a dynamic range of 130dB and total harmonic distortion of -120dB. The result is a richer musical experience with a purer sound background.
The BTR17 features a convenient and user-friendly three-mode switch (PC/BT/PHONE), allowing for seamless one-click switching between computer soundcard, Bluetooth DAC/amp, and smartphone tail DAC/amp modes. It automatically optimizes the power supply status based on the connected front-end device, offering versatile usage and greater peace of mind.
