FiiO BR15 R2R Hi-Res Bluetooth Receiver

BR15 R2R High-Resolution Bluetooth Audio Receiver with R2R DAC

The BR15 R2R is a compact wireless Hi-Fi receiver designed for listeners who want high performance without the clutter of cables. Combining Bluetooth 6.0, genuine lossless wireless codecs, and a fully balanced 24-bit R2R DAC, it integrates effortlessly into almost any audio setup. Connect it to active speakers, a trusted amplifier, or even an external DAC. Once added to your system, it opens the door to convenient streaming with a fresh, detailed presentation of your music library.

Qualcomm Bluetooth Platform with Lossless Support

Powered by Qualcomm’s flagship QCC5181 chipset, the BR15 R2R handles LDAC, aptX Adaptive, and aptX Lossless formats. With wireless bandwidth reaching up to 2.1 Mbps, it delivers stable, CD-quality lossless audio with precise detail. Simply pair a smartphone or tablet and enjoy the freedom to listen without being tethered to your system.

LDAC and aptX Lossless for Today’s Systems

For audio setups that lack modern wireless decoding, the BR15 R2R acts as the missing link. Built-in support for LDAC and aptX Lossless improves clarity and richness when streaming video, movies, or during extended listening sessions. It modernizes legacy systems while allowing newer setups to perform at their full potential.

Bluetooth 6.0 with Improved Range and Stability

Bluetooth 6.0 enhances signal robustness, reduces latency, and extends usable range. The external antenna helps maintain a solid connection even as you move around the room. Control playback from the sofa—or across the room—without interruptions or dropouts.

Fully Balanced 24-Bit R2R Digital-to-Analog Conversion

At the heart of the BR15 R2R lies a proprietary quad-channel, fully differential R2R DAC. Each channel employs 48 high-precision thin-film resistors, for a total of 192, rated at 0.1% tolerance with minimal thermal drift. This design delivers a lower noise floor, smoother backgrounds, and the organic texture prized by R2R enthusiasts. Users can select either NOS or OS mode to tailor the sound signature.

Multiple Digital Inputs for Flexible Use

Designed to adapt to diverse systems, the BR15 R2R allows seamless switching between Bluetooth, USB, and SPDIF inputs (coaxial and optical). Whether connected to a phone, computer, CD transport, or television, it integrates smoothly without locking you into a single source.

Versatile Analog and Digital Outputs

With dual RCA outputs, a balanced XLR output, and both coaxial and optical digital outputs, the BR15 R2R offers extensive connectivity. It can drive active speakers, feed an external DAC, or connect directly to an amplifier, making system changes quick and straightforward.

Global PEQ and Intelligent Auto EQ

A system-wide 10-band parametric EQ lets you fine-tune the sound across all inputs. Using the FIIO app, you can load preset curves or create custom EQ profiles. Frequency response correction and simulation are supported, and EQ curves can be exported or shared. AUTO EQ simplifies the process further by automatically matching headphone profiles to target curves.

Fully Balanced Audio Architecture

The entire signal path—from the R2R DAC through filtering and volume control—is fully balanced. This approach minimizes noise, keeps distortion under control, and preserves dynamic range. A dedicated pop-noise suppression circuit ensures silent power-on and power-off operation.

Dual AC/DC Power Options

An internal high-quality switching power supply ensures consistent performance during everyday use. For users with an external linear power supply, a 5V DC input is also available. When DC power is connected, the device automatically prioritizes it, allowing experimentation with different power characteristics.

Custom Color Display

The 1.47-inch color LCD displays track data, volume level, sampling rate, EQ status, and more. When paired with compatible Bluetooth sources, lyric display is also supported, offering a clear overview of system status at a glance.

Local and Remote Control Options

Dual front-panel knobs and the display provide intuitive control at close range, ideal for desktop use. From across the room, adjustments can be made via the included infrared remote or the FIIO Control app.
