The FiiO BR15 R2R is a wireless audio receiver with a high-resolution R2R DAC, featuring a fully differential 24-bit R2R DAC, Bluetooth 6.0, and Qualcomm's flagship QCC5181 chip. It supports LDAC, aptX Adaptive, and aptX Lossless codecs, delivering CD-quality audio at up to 2.1 Mbps.

The four-channel R2R DAC uses 192 precision thin-film resistors (48 per channel) with 0.1% tolerance, ensuring ultra-low noise and minimal distortion. The DAC can operate in NOS (no oversampling) or OS (oversampling) mode, giving users control over tonal character and detail retrieval.

The BR15 R2R integrates easily into any setup thanks to its Bluetooth, USB, coaxial, and optical inputs, as well as RCA, XLR, and digital outputs. It is compatible with active speakers, amplifiers, or external DACs, easily adapting to your playback chain.

It also features a global 10-band PEQ.
