BTR15 - Portable Bluetooth DAC and Headphone Amplifier

The FiiO BTR15 is an advanced portable Bluetooth DAC and headphone amplifier that elevates wireless and wired audio from your phone, computer, tablet, or portable player with detailed, high-resolution sound. Featuring Bluetooth 5.1 with support for LDAC, aptX Adaptive, aptX HD and other major wireless codecs, the BTR15 delivers rich, clear sound with strong connection stability. A Qualcomm QCC5125 Bluetooth chipset combined with an XMOS XU316 USB controller and dual ESS ES9219MQ DACs provides robust decoding in both Bluetooth and USB DAC modes.

A bright 0.96-inch OLED display shows playback information at a glance while built-in physical buttons make navigation intuitive. Mode switching allows seamless transition between Bluetooth, USB PC DAC, and Phone DAC modes, adapting to different listening scenarios. The inclusion of both 3.5 mm single-ended and 4.4 mm balanced outputs ensures compatibility with a wide spectrum of headphones and IEMs. A global parametric equalizer lets you tailor the sound signature to your taste, and the built-in battery offers long listening sessions on the go.
