Multi-device versatility

Switching between devices is effortless with the three position switch. You can move from desktop computer to Bluetooth connected headset to mobile phone in seconds, all using a single unit. This flexibility is ideal for users who cycle through work, travel, and personal listening.

• PC sound card mode lets the BTR13 act as a dedicated DAC for your computer.

High definition formats and outputs

The BTR13 uses the Qualcomm QCC5125 Bluetooth chip and delivers a broad range of formats. Supported formats include LDAC, aptX Adaptive, aptX HD, aptX LL, AAC and SBC. In both Bluetooth and USB DAC modes, it can reach up to 96 kHz sampling rate for high definition audio transmission.

• LDAC and aptX variants offer robust wireless performance with rich detail.
• A high sampling rate helps preserve nuance in complex passages and transients.

Per channel DAC and clear separation

Each stereo channel has its own Cirrus Logic CS43131 DAC. This dual DAC setup reduces crosstalk and preserves channel separation, yielding a purer sound from your headphones across the frequency range.

Tuning and personalization

Presets and fine tuning options make it possible to tailor the sound. There are preset effects, and you can share or download settings online. The app or web interface allows precise control over EQ frequencies, gain, and bandwidth.

• Presets present different tonal flavors while keeping clarity intact.
• Online sharing enables exchanging favorite settings with the community.
• App based controls let you adjust EQ, gain and bandwidth with precision.

Power, output and portability

The built in headphone amplifier has an independent power supply that maximizes output. The balanced two channel path delivers 220 mW per channel, a significant gain over prior models. The unit weighs 28.6 g, making it highly portable for daily carry.

Real world impressions

In real life you may notice more precise instrument textures, a wider soundstage, and clearer treble when used with compatible headphones. These outcomes depend on source quality and the rest of your listening chain, so experiences may vary.
