MQA support for master-quality sound

A new addition to the updated BTR5 2021 is support for MQA Renderer, allowing for high-resolution, master-level sound quality in reasonably sized files well-suited for your mobile device.



*Supports up to MQA 16x decoding with applicable music apps

*It is a Bluetooth receiver, which means it cannot be connected to a Bluetooth headphone/speaker.

A Thorough “Core” Upgrade

The core of the BTR5 has been renewed with the ES9219C DAC chip with better decoding performance, higher signal-to-noise ratio, and lower power consumption. Let a new chapter in wireless sound quality begin!

The Qualcomm CSR8675 is a low-power Bluetooth chip with enhanced audio capabilities, such as supporting 24-bit audio processing and possessing a 120 MHz DSP, allowing it to powerfully handle various Bluetooth decoding functions with ease.

Audiophile-approved performance

Utilizing an XMOS XUF208 control chip, the BTR5 2021 is capable of asynchronous audio decoding under USB Audio Class 2.0. As a USB DAC, the BTR5 2021 can decode up to 384kHz sampling rate and native DSD.


· Asynchronous USB DAC

· 384kHz support

· DSD256 (native DSD decoding)




*USB DAC functionality supports 2 modes, driverless USB 1.0 and high-performance USB 2.0 (the latter requires a driver from the FiiO website).

Fully equipped to tackle USB with power to spare

Your Bluetooth device can be transformed into a part of a Hi-Res Wireless setup by simply connecting it to the BTR5 2021. With the help of the BTR5 2021's Bluetooth version 5.0 supporting high-resolution formats such as AAC/SBC/aptX/aptX Low Latency/aptX HD/LDAC up to 96kHz, you can get a totally portable yet excellent sounding setup with your current device!


Change your experience, starting from the connection


FPGA precision clock management

An FPGA is responsible for the transmission and reception of Bluetooth and USB digital audio signals, as well as clock management. In the BTR5 2021, after the Bluetooth signal is processed through the FPGA, jitter is greatly reduced and signal stability is improved, completely solving the problem of different clock rates that exist between the different parts of the audio architecture.


*Tests have shown that Bluetooth music playback quality under LDAC is as good as local playback on a high-end audio player.

For greater power and detailed resolution, the BTR5 2021 features both balanced and single-ended outputs. In its balanced audio architecture, each channel is driven separately with its own DAC and amplifier, allowing the BTR5 2021 to bring a purer sound with unmatched finesse and balance.


* In order to ensure the BTR5 2021 operates normally, when both 3.5mm and 2.5mm outputs are inserted into, only the 3.5mm port will output sound.

Balance befitting of a flagship

2 microphones with cVc 8.0 noise cancellation

While the BTR5 2021 has a built-in omnidirectional high-sensitivity microphone, you can use an external microphone in a 3.5mm CTIA headset. When using either set of microphones, you can benefit from cVc 8.0 noise cancellation technology, which intelligently adjusts microphone gain and effectively suppresses background noise for crystal clear calls.



*When using OMTP headphones, audio output is guaranteed to work but the microphone and in-line controls may not work properly.

battery life


full of time

With a built-in 550mAh battery, the BTR5 2021 only takes 1.5 hours to fully charge but lasts for a length of 9 hours!


*3.5mm output, using AAC codec

Keeps you going all day

The one display shows all – a major feature of the BTR5 2021 is the crisp 0.49 inch 64x32 resolution OLED screen that displays pairing/connection/call status/power status/encoding format/volume. And with the display, you can call up a menu that allows you to visually view and adjust the charging status, enable car mode, change filters and EQ, etc.

Displaying its beauty for all

It's spunky, but it remembers for you too

When you connect the BTR5 2021 to your phone, the phone's volume and the BTR5 2021's volume can be adjusted separately, allowing you to better fine-tune the volume to your needs. The BTR5 2021 also conveniently remembers your desired volume.




*When paired with an iOS device, you can view remaining battery in the widget.

Transform into a USB audio adapter


When a USB connection is detected the BTR5 2021, it will automatically prompt you to turn on "USB Audio Adapter" mode, which turns off charging to the BTR5 2021 and allows you to use it as an audio dongle for your phone or other devices. 


*Standard Edition comes with a USB Type-C to Type-C cable




Shake Body into Cell Phone Tail

The new BTR5 supports switching to the "small tail" mode with one key. When a USB connection is detected, BTR5 will automatically jump out of the selection menu. Users can turn off the charging function and enter the mobile decoding mode by pressing any key.

Thoughtfulness in every detail

When connected to a phone and acting as a USB DAC, the BTR5 2021 can be configured to not needlessly drag power out of the phone. The dedicated in-vehicle mode allows the BTR5 2021 to automatically turn on and off with the car, further enhancing your convenience.

Scientifically precise, yet intuitive settings allow you to tune the BTR5 2021 to exactly your needs, such as – channel balance, 2 audio filters, and the 10-band equalizer. Of special note is the ability to adjust odd and even order harmonic distortion, allowing you to make the music warmer and colder to explore the sides of music you never knew about.



*The actual perceived effects of the above settings will depend on the listener.


Satisfy your music listening needs

With the addition of a dedicated FPGA, the 45.1584/49.152MHz dual crystal oscillators can more accurately reproduce audio signals under various sampling rates during Bluetooth and USB decoding.
