HiBy R4 MP3 & MP4 Player - HiFi Streaming DAP with WiFi & Bluetooth

In this review the HiBy R4 stands out as a focused choice for listeners who want a true portable HiFi experience plus modern streaming convenience. It combines an Android 12 platform with specialist audio hardware, and the single biggest reason to buy is its dedication to sound fidelity: system-wide SRC bypass, four DAC chips and separate PCM/DSD circuitry preserve resolution across local files and streaming services. The result is a versatile device for audiophiles who also want Spotify, Tidal and app access on the go.

Key Features

• Android 12 with SD665: Provides smooth navigation and app support so streaming services and video apps run reliably on the device.
• HiFi hardware: Four DAC chips, dual low-phase-noise crystals and 28 Tantalum capacitors yield improved resolution and reduced distortion for detailed playback.
• High-performance audio formats: Native DSD256, PCM up to 768kHz/32bit and MQA 16X support allow high-resolution files to play as intended.
• Flexible connectivity: Bluetooth 5.0 two-way and dual-band WiFi let users stream, pair wireless headphones or cast audio while keeping high-definition codec options.
• Expandable storage and memory: 3GB RAM, 32GB internal and microSD expansion up to 2TB cover large local libraries and offline storage needs.
• Practical design: 4.7 in screen, 4500mAh battery and both 3.5mm and 4.4mm balanced outputs give long playback and versatile headphone compatibility.

Who It's For

The HiBy R4 is aimed at music enthusiasts who prioritize audio fidelity but also want modern streaming: users who want offline playback of high-resolution files and the convenience of services like Spotify, Tidal and web-based players on an Android platform. It is ideal for headphone listeners who benefit from balanced output and a dedicated Class A headphone amplifier for dynamic, low-noise listening.

Less suitable audiences include casual buyers who only need a basic Bluetooth music streamer or those seeking the simplest possible interface; the R4 has more features and a learning curve for optimal setup. If ultimate portability at the expense of dedicated hardware quality is the main goal, a simpler player or phone may be a better fit.
