FiiO BTR3K Bluetooth 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.

The new BTR3K has an aluminium alloy body wrapped elegantly in an arc of 2.5D glass, with oleophobic coating that keeps off fingerprints, high contrast black lettering and smooth texture give the compact BTR3K an elegant look. It includes RGB light indicator that quickly tells you what format is currently being used.

Robust full-bodied sound

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.

-107dB Distortion | 122dB Signal Noise Ratio | 78mW Output power balance | 25mW Output power SE

Independent dual crystal oscillators

The dual crystal oscillator system in the BTR5 also comes to the BTR3K! The 22.5792M/24.576 MHz dual crystal oscillators meant 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.

A robust inner core

The Qualcomm CSR8675 Bluetooth chip used in the BTR3K is 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 decoded multiple lossless Bluetooth codecs. No matter whether you are watching videos, listening to music or enjoying your favourite 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 / aptXLL / aptX HD / LDAC audio formats that you’ll get the best sound quality possible from the BTR3K.

Listen and charge with USB Type-C

You can listen while charging with the USB Type-C connector. As a matter of fact, the BTR3K takes only 1.5 hours to fully charge but allows for a lengthy 11 hours of playback!

Crystal-clear calls free of noise

The built-in amplifier in the BTR3K not only ensures your music sound good, but that your calls do too. To further enhance your calling experience the BTR3K is not only equipped with your calling experience the BTR3K is not only equipped with omnidirectional microphone and phone controls, it is also equipped with the eight generation technology, which effectively suppresses background noise so that your call comes through as clear and audible as possible.

Flexibility specialist

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.

Great connection convenience

The BTR3K can be paired with, and remember, up to two Bluetooth devices at once, allowing for even more convenience. Simply use whichever device you want to pair the BTR3K anytime without hassle!

Quick and convenient volume control

When you connect the BTR3K to your Bluetooth device, the device’s volume and the BTR3K’s volume can be adjusted separately, allowing you to better fine-tune the volume to your needs. 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.

Smart assistant access
