BTR3K-Balanced HiFi Bluetooth Amp

Flexibility specialist

Adapts to various kinds of
wired headphones

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 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.

Captivating you through your fingers

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 give the compact BTR3K an
elegant look that would not be out of place in a specialty
artisan's shop.

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.

You should be able to take your music with you wherever.

The BTR3K comes with a symmetrical, detachable rear clip that allows you to easily carry it around.

Free to go with

you wherever

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!

Great connection convenience

Supports pairing to 2 devices simultaneously

Simply use the BTR3K to call up your smartphone's assistant
without even having to pull it out.

Give a holler when you
need help

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.

Robust, full-bodied sound
High performance AK4377A DACs

Building off of 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.

Now with balanced and SE output

Incredible performance gains

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 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 built-in amplifier in the BTR3k not only ensures your music
sounds good, but that your calls do too. To further enhance
your calling experience the BTR3k is not only equipped with
omnidirectional microphone and phone controls, it is also
equipped with the eight generation Qualcomm's cVc noise
cancellation technology, which effectively suppresses
background noise so that your call comes through as clear
and audible as possible.

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 that you’ll get the best sound

quality possible from the BTR3K.

Speedy Bluetooth

connection

When your device is connected to the BTR3K and is using the
FiiO Music app to play music, the BTR3K can be remotely
controlled with the following functions.

Intelligently puts your
