FiiO BTR25 Portable Bluetooth DAC and Headphone Amplifier VINTAGE GOLD

The FiiO BTR25 is a compact, high-performance portable Bluetooth DAC and headphone amplifier designed to deliver detailed, high-quality audio from wired headphones and in-ear monitors. Combining the Qualcomm QCC3095 Bluetooth processor, ESS ES9069Q digital-to-analog converter and dual ESS ES9603Q headphone amplifiers, the BTR25 provides advanced wireless audio technology and powerful headphone amplification in a lightweight aluminium-alloy enclosure.

Featuring Bluetooth 6.2 with support for aptX Lossless, aptX Adaptive, LDAC and LE Audio, the BTR25 allows compatible smartphones, tablets and other Bluetooth sources to stream high-quality audio to traditional wired headphones. Its dedicated SPV5048 USB audio processor also supports high-resolution wired playback up to 32-bit/384 kHz PCM and native DSD256 with compatible source devices.

Three selectable operating modes provide convenient integration with computers, smartphones and wireless audio sources. A vivid 1.3-inch colour IPS display presents playback information and device status, while the precision rotary volume control, dedicated buttons and detachable magnetic clip make the BTR25 easy to operate and carry. Both 3.5 mm single-ended and 4.4 mm balanced headphone outputs are provided.

Finished in Vintage Gold, the BTR25 combines distinctive geometric styling with a refined metallic appearance. Additional conveniences include FiiO Control app compatibility, adjustable volume curves, game mode, car mode, firmware updates and integrated protection circuitry.
