FiiO BTR15 Wireless Bluetooth DAC Amp with Dual ES9219MQ DAC and LDAC

The FiiO BTR15 is a portable wireless DAC amp built for listeners who want desktop-level sound in a pocket-sized device. Powered by a dual ES9219MQ DAC setup and the Qualcomm QCC5125 Bluetooth chip, it delivers clean, detailed audio whether you're pairing it wirelessly with your phone or connecting it via USB to a laptop.

What sets this FiiO Bluetooth DAC amp apart is its flexibility. It supports nearly every major Bluetooth codec, including LDAC, aptX Adaptive, and aptX HD, so high-resolution wireless listening is possible from a wide range of source devices. For wired setups, the XMOS XU316 USB chip enables driver-free USB DAC operation at up to 384kHz/32-bit and DSD256.

Real-world use is simple: commuters get strong wireless sound quality without cables, while desktop users get a compact USB DAC/amp that outputs enough power to drive both easy-to-power IEMs and demanding over-ear headphones through its dual 3.5mm and 4.4mm balanced outputs.
