FiiO BTR3K

FiiO new version of the BTR3K compact Bluetooth receiver and headphone amplifier. It is intended for those who are not satisfied with the sound of TWS headphones and who want to continue using their favorite in-ear monitors wirelessly.

Inside the miniature case, a Bluetooth CSR8675 chip from Qualcomm is installed, which provides support for all major codecs, including audiophile ones - SBC, AAC, AptX, AptX HD, AptX Low Latency and LDAC. In addition, the model is capable of simultaneously working with two wireless audio sources. The diodes built into FiiO BTR3K light up in different colors depending on which codec is involved.

A dual DAC AK4377A is responsible for converting a digit to an analog, two outputs are intended for connecting headphones - a balanced 2.5 mm and a regular 3.5 mm. The balanced output voltage reaches 78 mV at 32 Ohm load.
