BTR13 - Portable Bluetooth DAC & Headphone Amplifier

The FiiO BTR13 is a versatile portable Bluetooth DAC and headphone amplifier designed to upgrade wireless and wired audio from phones, tablets, computers, and other digital devices. Featuring Bluetooth 5.1 with support for high-resolution codecs including LDAC, aptX Adaptive, aptX HD, AAC, and SBC, it delivers detailed, dynamic sound with improved clarity over standard Bluetooth audio.

Equipped with dual high-performance Cirrus Logic CS43131 DAC chips and a dedicated headphone amplifier power supply, the BTR13 provides strong output power capable of driving a wide range of headphones with both balanced and single-ended connections. A 0.96-inch full-color IPS display provides quick visual feedback of sample rate, mode, and settings.

With seamless one-click switching between Bluetooth, USB DAC, and phone USB dongle modes, the BTR13 adapts to multiple use cases — from acting as a Bluetooth decoder to functioning as a USB sound card for computers or an audio dongle for mobile devices. Additional features include patented car mode automatic on/off, inline control support, built-in microphone for calls, and app adjustable global parametric EQ for tailored sound tuning.
