FiiO BTR1K Portable High-Fidelity Bluetooth Amplifier
The FiiO BTR1K is a Bluetooth receiver with an integrated DAC. It is intended to give you, the listener, a more refined, detailed, articulate, and sonically pleasing experience when listening to music over Bluetooth. The previous iteration of this receiver also purported to mitigate the sonic inferiority of the Bluetooth experience, but this version takes things a step further with a new Qualcomm QCC3005 Bluetooth chip, one that handles Bluetooth 5.0.
The BTR1K also sports an upgrade in regards to digital-to-audio conversion, thanks to the AK4376A DAC. This model provides a lower noise floor than its previous incarnation, as well as a higher signal-to-noise ratio and more output power. This DAC is housed alongside FiiO's Bluetooth Chip architecture to provide support aptX, aptX Low Latency, SBC, and AAC codecs.
Surrounding these components is a sleek aluminum-alloy chassis, which can stylishly clip onto your shirt pocket or shoulder strap. A microphone is provided so you can take phone calls in between tunes. A built-in rechargeable battery lasts for eight hours, ensuring you can listen to music wirelessly for a long time. If your iOS or Android device doesn't have a 3.5mm headphone jack, this can serve as a high-quality method to stream great sounding music.
Long Battery Life
The built-in rechargeable lithium battery charges to full capacity in 1.5 hours and lasts up to 8 hours at a clip. The battery sports a 205mAh battery capacity.
Clear Status Indicators
The blue and red lights on the BTR1K instantly show you the codec you're using as well as the charging and working status
Strong and Compact Aluminum-Alloy Body
The BTR1K sports a sleek, aluminum-alloy body finished in black. Its compact, yet stylish design fits easily in your pocket or clips to your backpack shoulder strap.
