FiiO BTR13 black

The FiiO BTR13 is a portable headphone amplifier that builds on the BTR3K. It offers a dual CS43131 chip with a fully balanced output, delivering more than double the output power. It also features a QCC5125 Bluetooth chip, which supports Bluetooth 5.1. While both devices have a 3.5mm unbalanced output, the BTR13 now features a 4.4mm balanced jack instead of the original 2.5mm one. For a more user-friendly experience, the amplifier is newly equipped with a 0.96" IPS display instead of just an indicator light. It also has a customisable equaliser that applies to all 3 playback modes: Bluetooth, PC, and PHONE. The difference between PC and PHONE mode is that in PC mode, the USB-C port is used for both data transfer and powering the device. In PHONE mode, the USB-C is used only as an audio input and the device is powered by its internal battery. Compared to its predecessor, the BTR13 offers playback up to 96kHz quality with a bitrate of up to 990 when using the LDAC codec. The package also includes a clip for more comfortable outdoor use.
