FiiO BTR3 Bluetooth Headphone Amp

 The Fiio BTR3 is a compact and lightweight Bluetooth amplifier - The first Bluetooth amplifier in the world to support all current wireless audio codecs, such as AAC, SBC, aptX, aptX Low Latency, aptX HD, LDAC, LHDC and HWA. Simply connect your ACS cable, or any other device with a 3.5mm connector, to the BTR3 and you're ready to go.  The Qualcomm CR8675 Bluetooth chip used in the BTR3 is a premium low-power solution designed for enhanced audio applications, with support for 24-bit transmission and processing thanks to its 120MHz DSP. This chip is also much more stable in signal strength than other competing chips, especially in situations with lots of interference. The AK4376A DAC, with its extremely low -107 dB distortion and extremely high 124 dB Signal-to-Noise ratio, means that you will be able to catch every last nuance and detail in your music & communications.  The 300 mAh battery takes only 1.5 hours to fully charge but allows for a lengthy 11 hours of playback.
