The FiiO BTR3 is a portable Bluetooth amplifier designed for two purposes: to give your headphones a robust signal and to communicate with compatible devices over Bluetooth 4.2. The device supports audio codecs such as AAC, SBC, aptX, aptX Low Latency, aptX HD, LDAC, and LHDC. The onboard amplifier and DAC ensures a quality sound that will bring out the best in your music. NFC pairing ensures you can pair with devices more quickly.
A Qualcomm CSR8675 Bluetooth chip has been supplied, one that supports 24-bit transmission and processing to preserve your music's dynamic range and stability in most locales, preventing dropouts when possible. The independent AK4376A DAC/amp chip offers low levels of distortion and a high signal-to-noise ratio to ensure a sonic experience that is high on nuance and low on sonic impediments. Connect your headphones to the BTR3 by means of the 3.5mm stereo jack.
Controls and indicators are on hand so you always know which input codec is selected at any given time, and so you're always able to switch tracks, make phone calls, start/stop your music, and contact your digital assistant. A built-in microphone allows for hands-free calls. A remote control app facilitates even more control.
In addition to serving as a go-between for headphones and devices, the BTR3 is also a high-quality USB DAC with a USB Type-C connector, so you can upgrade the sound of your computer.
