Bluetooth 6.0 Next-level connectivity

With high efficiency and minimal power draw, and the added advantage of a dedicated external antenna, this device achieves extended range, enhanced resistance to interference, lower latency, and superior connection stability - offering you greater wireless freedom.

FULLY DIFFERENTIAL 24-BIT R2R DAC

At the center of the BR15 R2R is a proprietary quad-channel, fully-differential R2R DAC. Each channel uses 48 precision thin-film resistors—192 total—with 0.1% accuracy and low temperature drift. The result is a darker noise floor, a smoother background, and the kind of texture R2R fans love. You can run the DAC in NOS or OS mode, depending on the character you prefer.

Fully balanced audio circuit

The entire signal path—from the R2R DAC and LPF to the volume control— uses full-differential signal handling, resulting in low noise, minimal distortion, and large dynamic range.

Furthermore, it is equipped with a pop noise elimination system, which further guarantees the integrity and robust nature of the audio circuitry.

AC/DC dual power supply design

The internal high-quality switching power supply ensures the device is fed with clean power. It is also equipped with an external DC power port*, giving you the flexibility to pair the device with a high-performance linear power supply and unlock a new sound.

*When using external DC power, ensure the power supply provides 5V output, ≥2A current, and uses a 5.5×2.1mm jack.

*The device automatically switches to prioritize DC power when a DC source is connected.

Custom LCD display Song info clear at a glance

The custom 1.47-inch color display offers various themes and clearly presents the song title, artist, and lyrics* during Bluetooth playback.

Users can also quickly check device status information like the sampling rate, volume, and EQ settings.

* Lyrics display requires the Bluetooth transmitting source to be compatible with the BR15 R2R. When using the FIlO Music App, activate the "External Device Bluetooth Lyrics" function in the settings.
