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.
Now with balanced and SE output
Incredible performance gains
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.
Robust, full-bodied sound
High performance AK4377A DACs
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 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
Qualcomm CSR8675 Flagship-level Bluetooth abilities
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 that you’ll get the best sound quality possible from the BTR3K.
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.
- Blue light: SBC
- Cyan light: AAC
- Purple light: aptX/aptX LL
- Yellow light: aptX HD
- White light: LDAC
Listen and charge with 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 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.
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.
Great connection convenience
Supports pairing to 2 devices simultaneously
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.
Give a holler when you need help
Simply use the BTR3K to call up your smartphone's assistant without even having to pull it out.
Intelligently puts your music at your fingertips
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.
Free to go with you wherever
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.
Use It Everywhere
- Get your music on the road
- Give your older speaker new life
