HiBy M300 (3+32GB) Digital Audio Player

The M300 asks a different question than the rest of HiBy's DAP lineup: not how close to the fidelity ceiling can a player get, but how much real Android functionality can fit into a pocketable, audio-first device. Built under HiBy Digital, the company's newer lifestyle-focused sub-brand, the M300 runs full Android 13 with streaming apps, FM radio, and a built-in speaker, while still carrying a dedicated Cirrus Logic DAC and headphone amp underneath.

Type and Technology

• Qualcomm Snapdragon 665 octa-core SOC (11nm, Adreno 610 GPU) running Android 13 with Google Play access
• Cirrus Logic CS43131 DAC paired with an OPA1652 amplification stage
• Native DSD256 decoding and PCM up to 32bit/768kHz
• 3GB RAM, 32GB internal storage, microSD expansion up to 2TB
• Dual-band 2.4/5GHz WiFi and Bluetooth 5.0 with LDAC

Sound Character

Reviewers describe an engaging, musical signature with solid bass impact, smooth mids, and treble that stays on the easy side of fatiguing rather than clinical. It's consistently called very good for the price rather than a giant-killer, and pairs especially well with warmer or brighter IEMs. At 103mW into 32 ohms it has plenty of headroom for IEMs and easy to drive headphones, though it isn't built to push demanding full-size cans.

Build and Comfort

• Unibody aluminum chassis with glass front and back panels
• 4 inch IPS touchscreen, 1280 x 640
• 113 x 58 x 13mm, 136g
• Available in Black, Silver, and Blue

Best For

• Listeners who want one pocketable device for music, casual streaming apps, and everyday Android convenience instead of carrying a phone plus a separate DAP
• A friendlier, more affordable on-ramp into the HiBy lineup than the more single purpose R-series players
• Anyone who wants FM radio, voice recording, and a built-in speaker alongside dedicated DAC hardware
