Three‑mode versatility for everyday use

Hi‑Fi wireless and wired clarity

Powered by the Qualcomm QCC5125 Bluetooth chip, the BTR13 supports LDAC, aptX Adaptive, aptX HD, AAC, SBC, and more. Whether streaming over Bluetooth or using USB DAC, you can enjoy up to 96 kHz sampling rate for nuanced detail and a wide dynamic range.

• LDAC and aptX family support for high‑resolution wireless listening.
• USB DAC mode ensures a high‑quality digital pathway when connected to a computer or phone.

The audio path is further refined by dual Cirrus Logic CS43131 DACs, with one DAC processing each stereo channel. This dedicated architecture helps reduce crosstalk and preserves stereo imaging, letting details feel more anchored and precise.

Personalized sound, made easy

No need to guess your EQ setup. The BTR13 ships with preset effects and supports online sharing. You can also fine‑tune EQ bands, gain, and bandwidth through FiiO’s app or web interface, so you can tailor your sound to your headphones or genre.

• Presets kick in quickly for different styles or genres.
• Fine‑grained controls give you flexibility to shape the tone and impact.

Power, portability, and performance

At only 28.6 g, the BTR13 blends portability with robust output. Its independent power supply for the built‑in headphone amplifier drives the balanced 4.4 mm output at 220 mW + 220 mW, delivering a strong, clean signal that suits a range of high‑impedance headphones.

• Balanced 4.4 mm output provides more headroom and a wider soundstage.
• Pocket‑friendly design supports on‑the‑go listening without compromise.

In short, the BTR13 positions itself as a versatile companion for desktop, travel, or daily commutes—offering flexible inputs, high‑res wireless options, and user‑friendly tuning, without promising results beyond what your setup may achieve.
