DESCRIPTION
A CAPTIVATING DESIGN THAT FEELS SILKY SMOOTH TO THE TOUCH
Smartphones are designed to be convenient and therefore the FiiO BTR3K mirrors a smartphone design for your ease of use. The aluminium alloy body and a glasslike structure add a sense of style to the overall design. An oleophobic coating on the BTR3K keeps fingerprints away. To add a touch of artistic elegance, the FiiO BTR3K uses lettering and smooth texturing.

ELEVATE TO INCREDIBLE GAIN PERFORMANCE WITH BALANCED & SINGLE-ENDED OUTPUTS
Building on the best aspects of the BTR3, the all-new FiiO BTR3K goes a step ahead to add balanced output. Sporting a pure balanced design, the BTR3K features a DAC and amplifier that are tuned for the left and the right audio channels. This exquisite arrangement is the heart of the BTR3K that propels the purest sound possible.

MORE POWER AND ACCURATE SOUND DRIVEN BY AK4377A DACS & DUAL CRYSTAL OSCILLATORS
The power output of the all-new FiiO BTR3K is practically double the power output of the BTR3. This is the direct result of the high-performing AK4377A DACs used in the newer variant that improves measurements and the overall sound. These DACs are paired with the 22.5792M/24.576 MHz dual crystal oscillators. These simply extend the BTR3K’s capacity to produce accurate audio signals by reducing jitter and enhancing audio stability. So regardless of the sampling rate, which you are working on, the FiiO BTR3K consistently registers accurate sound.




EXPLORE PREMIUM-LEVEL BLUETOOTH 5.0 FUNCTIONS WITH THE QUALCOMM CSR8675 CHIP
Multi-device pairing and robust wireless connectivity are among the finest features of Bluetooth 5.0 which is utilized in the FiiO BTR3K. The Qualcomm CSR8675 Bluetooth chip installed in the FiiO BTR3K operates on less power. It is designed particularly for enhanced audio applications. Experience the world of high-quality digital music with the BTR3K as it supports 120 MHz DSP, 24-bit transmission and processing along with the ability to decode a range of lossless Bluetooth codecs including AAC, SBC, aptX, aptX LL, aptX HD & LDAC. Watch movies, play games and listen to music with quality sound always at your service.



IT’S ALL ABOUT CONVENIENCE & FLEXIBILITY WITH THE RGB LIGHT INDICATOR & AN 11-HOUR PLAYTIME
The moment you plug a headphone into your BTR3K, it automatically adjusts the output and if the headphone has CTIA controls you can use it to manage your music. Using multiple Bluetooth formats at multiple places might get confusing, but not with the FiiO BTR3K as it comes with the RGB light indicator. This light indicator displays the currently used format waste time keeping the track. It takes around 1.5 hours to fully charge the BTR3K while it gives you up to 11 hours of music playback. You can even charge the BTR3K while you are listening to music, all thanks to the USB-C Type C connector.



CRYSTAL-CLEAR VOICE CALLS WITH A NOISE CANCELLING OMNIDIRECTIONAL MICROPHONE
The amplifier at the core of the FiiO BTR3K is not just for quality sound but also for crystal clear audio calls. Packed with an omnidirectional microphone and phone controls, the BTR3K lets you handle voice calls with utmost clarity. To further aid calling convenience, the BTR3K is equipped with 8th generation Qualcomm cVc noise cancelling technology. So the next time you are on a call, make sure your voice is heard with clarity and without noise.



TAKE COMPLETE CONTROL OVER YOUR BTR3K WITH THE FIIO MUSIC APP
When you connect your FiiO BTR3K to a Bluetooth device, you get two volume controlsโone on the Bluetooth device and the other on the BTR3K. This allows you to control the sound with better precision. The BTR3K is a smart device, it’s compatible with voice assistants and remembers your preferred volume level so that you don’t have to change it every time. You can get even better control over your music by using the FiiO Music App that has a 10-brand professional equalizer, channel balance and 4 audio filters. With a detachable ear clip included, you can carry the BTR3K around, easily.



PAIR IT WITH YOUR OLD SPEAKER, PC OR YOUR CAR AND NEVER MISS HIGH-QUALITY MUSIC
Listen to music while you are driving with the dedicated car mode. Kindly note that when the BTR3K is connected to the car via USB, it will start and stop along with the car. You can spice up your old speaker by simply connecting it to the BTR3K via a 3.5mm jack for a wireless music listening experience. Pair it with your computer or laptops to improve the sound quality.
