🎯 Deep Dive: HiBy R4 & R3 II 2025
🚀 HiBy R4: The Android Powerhouse
The HiBy R4 is an Android 12 DAP powered by a Snapdragon 665, 3GB RAM, and a quad-ES9018C2M DAC configuration. It supports 32-bit/768kHz PCM and DSD256, with both 3.5mm SE and 4.4mm BAL outputs delivering up to 525mW of power. A Pure Audio Mode disables Android distractions for critical listening, and the MSEB system-level tuning lets you shape the sound to your IEMs.
Yahoo Tech praised the R4 for its ability to “focus only on the music” and called it the “best decision” for moving away from a smartphone. However, they noted its bulky, 231g weight makes it less portable for physical activities. A user on Amazon Canada mentioned the screen brightness is dark under sunlight and the device is heavy to carry.
🎵 HiBy R3 II 2025: The Compact Contender
The HiBy R3 II 2025 is a featherweight (118g) player with a 3.2-inch screen, dual ESS ES9219C DACs, and a balanced output providing 380mW. It runs HiByOS, which is not Android-based but supports TIDAL and Qobuz streaming via Wi-Fi (2.4GHz only).
User reviews on Amazon UK highlight its great soundstage, depth, and detail, with a warm tuning that punches above its price. A verified buyer compared its sound to the much more expensive Sony NW-WM1AM2, stating “This sound is just as good”. However, a common complaint is the Wi-Fi is limited to 2.4GHz, causing connectivity issues for some.
✅ HiBy STRENGTHS
- Value for Money: High-end DACs and powerful amps at accessible prices.
- Android Flexibility: R4 runs full Android 12, offering unlimited streaming apps.
- Unique Tuning: MSEB and Pure Audio Mode offer unmatched customization.
- Bold Design: Cyberpunk aesthetic stands out in a sea of bland DAPs.
❌ HiBy WEAKNESSES & RISKS
- ⚠️ Bulk & Weight: R4 is heavy (231g) and not pocket-friendly.
- ⚠️ QC & Support Concerns: Some users report issues like poor Wi-Fi or support difficulties.
- ⚠️ Limited Connectivity: R3 II only supports 2.4GHz Wi-Fi, a drawback in 2025.
- ⚠️ Screen & Usability: R4 screen may be dim in sunlight; touch sensitivity can be less responsive than a smartphone.
🗣️ What Users Are Saying (Real Reviews)
“Great soundstage, poor wifi connection” – Amazon UK, June 2025.
“It gives a mighty sound, great soundstage, depth and detail. The sound to me is warm rather than being analytical. … The thing that is disappointing with this device is the WiFi connection. I have not been able to connect to the internet so can’t stream Tidal.”
“Superb value DAP… sound neutral, very good dynamics” – Amazon UK, Nov 2025.
“It is significantly better than my 4-year-old IFI Hip Dac… The sound has very neutral tonality, very good dynamics, and has a surprising amount of ‘space’ around it.”
“Meilleur dac pour le prix” – Amazon Canada, Aug 2025.
“Pro: Looking beautiful, good to listen to music while you can watch or do online. Con: screen brightness is very dark, hard to see the screen under sun light. Too heavy so its hard to carry on your pants.”
