Simply plug your headphones or earphones into the FiiO BTR5 and pair the BTR5 with the player via Bluetooth. Now you can enjoy your music in first-class Bluetooth quality and make wireless calls. In order to support both unbalanced headphones with 3.5 mm standard connectors and balanced headphones with 2.5 mm connectors, the BTR5 provides both types of connectors. The BTR5 supports all popular Bluetooth codecs such as SBC, AAC, aptX, aptX Low Latency, aptX HD and LDAC. Thus, the music arrives at the connected headphones in full bandwidth and an excellent sound quality with very high detail is possible. The Qualcomm Bluetooth chip CR8675 used in the FiiO BTR5 ensures stable data transmission at a transfer rate of up to 24 bits. The two Sabre ES9218PC HiFi DAC chips contribute significantly to error-free performance and lifelike high-resolution music playback. The buttons on the BTR5 control the most important functions such as track forward/backward, volume +/-, play/pause and answer/reject/end calls. In addition, the BTR5 can be used on a PC as a USB DAC to improve the sound quality from your computer. The BTR5 also performs well in the car. It can be connected to the car hi-fi system via a 3.5 mm cable and you can now listen to music from your smartphone or music player wirelessly in the car via the car speakers and, of course, make wireless calls. A microphone for telephone calls or for using a voice assistant is integrated on the BTR5. The BTR5 is equipped with a rechargeable battery with a runtime of up to 9 hours. The case is made of light and robust aluminium and is coated with 2.5D glass at the front and back, leaving no fingerprints. The included transparent case with detachable clip protects the BTR5 perfectly and can be attached to your clothes or a bag strap if desired.
