HiFi Audio Player with Android 12

The BFKK HiBy R4 runs Android 12 on an SD665 octa-core processor with 3 GB RAM and 32 GB internal storage. It supports streaming apps such as Spotify, Tidal and YouTube alongside local playback. A micro-SD slot allows expansion up to 2 TB for large media libraries. The 4.7-inch LCD provides a clear interface for navigation and video.

Dual Headphone Outputs and Wireless Connectivity

A 3.5 mm single-ended jack and a 4.4 mm balanced jack connect directly to the integrated Class A headphone amplifier. Four DAC chips, two low-phase-noise crystals and 28 tantalum capacitors form a dual-circuit design that switches automatically between PCM and DSD paths. Bluetooth 5.0 with LDAC, aptX HD and UAT codecs plus dual-band WiFi 4 handle wireless audio and app downloads.

High-Resolution Playback up to DSD 256 and PCM 768

The player decodes DSD 256 native, PCM 768 kHz / 32-bit and MQA 16X unfolding without conversion. Independent DAC, filter and power-supply circuits for each format reduce high-frequency noise and preserve dynamic range. Hi-Res Audio and Hi-Res Audio Wireless certifications confirm the signal chain meets the stated specifications. A 4500 mAh battery powers extended listening sessions.
