FiiO BTR3K Bluetooth DAC and Headphone Amp

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. 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.

The 22.5792M/24.576 MHz dual crystal oscillators mean that during Bluetooth and USB decoding, the BTR3K can more accurately reproduce audio signals under various sampling rates – due to greatly reduced jitter and greatly increased audio stability. 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. Support for the AAC/SBC/aptX/aptX LL/aptX HD/LDAC audio formats ensure that you’ll get the best sound quality possible from the BTR3K.

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

The BTR3K can automatically tell what kind of headphones you plugged into it and adjusts its output accordingly. And when you plug in headphones with CTIA controls, you can use the microphone as well as the play/pause, volume, and track selection controls. The BTR3K can be paired with and remember up to two Bluetooth devices at once, allowing for even more convenience. The BTR3K also remembers your desired volume, so you don’t have to adjust the volume to where you want it every time you use the device. With the help of the BTR3K’s USB DAC functionality, you can listen to music on your computer with massively improved quality. Simply connect your headphones to the BTR3K while it is connected to your computer and enjoy your music on there whenever
