Enjoy hi-res wireless Bluetooth

Utilizing an Audiophile-approved performance bluetooth chip 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.

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 portable sounding setup with your current device!

After you using it you would change your original opinion on the experience for bluetooth hi-res sound.


High-performance DAC ES9219C*2 The core of the BTR5 bluetooth receiver 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!	Supports MQA A new addition to the updated BTR5 2021 bluetooth headphone amp is support for MQA Renderer, allowing for high-resolution, master-level sound quality in reasonably sized files well-suited for your mobile device. PS: Supports up to MQA 16x decoding with applicable music apps.	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.	Dual crystal oscillators Independent dual crystal oscillators for accurate audio reproduction. 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.

XMOS XUF208 control chip, supports 384kHz/DSD256

(1)The BTR5 2021 bluetooth amplifier 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 DSD256 decoding.

(2)USB DAC functionality supports 2 modes.

(3)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.

Good performance also with its battery

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

Displaying its beauty for all

The one display shows all – a major feature of the BTR5 2021 portable amplifier 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.
