HiBy R4 Android MP3/MP4 Player — 4 DACs, Class A Amp, MQA 16X, Spotify, Bluetooth & WiFi

HiBy R4: A portable HiFi companion for modern listening

The HiBy R4 is crafted for listeners who seek refined sound in a compact, versatile device. It combines four ESS ES9018C2M DACs with four OPA1652 Class A amplifiers to deliver a warm, detailed voice and instrument textures across genres. The design focuses on low distortion and a clear signal-to-noise balance, aiming to reveal subtle musical cues without fatigue during long sessions.

A standout feature is the dual PCM and DSD decoding architecture. By separating the two channels, the R4 reduces crosstalk and ambient noise, supporting native hardware decoding for a broad range of formats. This approach helps preserve the nuance of studio masterings and live recordings when you switch between local files and online streams.

Smart platform, flexible playback

Operating on Android 12, the R4 runs an octa-core processor with 3GB of RAM and 32GB of built-in storage, balancing responsive navigation with ample room for your music and apps. It enables free installation of popular streaming services such as Spotify, Apple Music, Tidal, and Amazon Music, letting you blend MP3 and MP4 playback with on-demand listening in one device.

For audiophiles who chase premium formats, the HiBy R4 supports MQA 16X unfolding and a wide range of PCM and DSD formats. This hardware-assisted decoding helps reproduce higher-resolution details from compatible tracks and videos, contributing to a more immersive listening experience without relying on external gear.

Connectivity that matches your listening setup

Wireless connectivity includes Bluetooth 5.0 with LDAC and aptX HD, along with dual-band Wi‑Fi, enabling fluid streaming and smoother app performance. On the hardware side, you get versatile listening options with a 3.5mm output and a 4.4mm balanced port, plus a multi-functional USB-C connector for charging, data transfer, or USB audio interfaces.
