Silky smooth surface

The aluminum alloy body wrapped elegantly in an arc of 2.5D glass like that used in the latest smartphones, the oleophobic coating that keeps off fingerprints, the high contrast black lettering, and the smooth texture gives the compact BTR3K an elegant look that would not be out of place in a specialty artisans shop

Now with balanced SE output incredible performance gains

Building off what made the btr3 so good, the BTR3K implements balanced output. it is a truly balanced design, with a DAC and amplifier carefully paired for the left and right channels each, for the purest sound possible

Robust, full-bodied sound High performance AK4377A

With two high-performance AK4377A DACs, the power output has increased by 50% compared to the AK4376 used in the BTR3 as well as greatly improved measurements and actual sound.

Independent dual crystal oscillators for accurate audio reproduction 

The dual crystal oscillator system in the BTR5 also comes to the BTR3K! the 22.5792M/24.576 MHz dual crystal oscillators mean that during Bluetooth use USB decoding, the BTR3K can more accurately reproduce audio signals under various sampling rates- due to greatly reduced jitter and greatly increased audio stability.

A robust inner core

The Qualcomm CSR8675 Bluetooth chip used in the BTR3K is a premium low-power solution designed for enhanced audio applications, with a 120 MHz DSP, support for 24-bit transmission and processing as well as abilities to decode multiple lossless Bluetooth codecs. No matter whether you watching videos, listening to music, or enjoying your favorite game, this chip will ensure you get excellent sound quality.

Speedy Bluetooth connection

The BTR3K upgrades to Bluetooth 5.0, which means faster pairing and more stable signal strength for a better overall experience. It fully supports AAC/SBC/aptX/aptX LL/aptX HD/LDAC audio formats which means that you’ll get the best sound.

An extremely useful little light

With so many Bluetooth formats being used in various places, the RGB light indicator quickly tells you which format is currently being utilized.
