UGREEN HiTune S3 True Wireless Earbuds (model SKU 45785 and variants) are budget-friendly open-ear clip-on wireless earbuds from UGREEN, designed for situational awareness, sports, running, cycling, commuting, or workouts. They use an air-conduction/open-ear approach (no in-ear insertion), so you stay aware of surroundings like traffic or conversations while listening.Key Features
- Open-Ear Clip Design for Comfort & Security: Ultra-lightweight at just 5.3g per bud with a flexible C-shape/memory ear clip made of durable titanium alloy + TPE material. It clips securely onto the ear edge without blocking the canal—pressure-free for long wear (all-day comfort), adjustable to most ear shapes, and stable during movement.
- Audio Quality: 12mm dynamic drivers with composite polymer diaphragms for deep bass, rich mids, and crisp trebles (impressive for open-ear). Directional acoustics minimize sound leakage (up to 98% reduction). Supports SBC/AAC codecs; low latency mode at 0.06s for gaming/videos.
- Calls & Noise Handling: Built-in ENC/AI noise cancellation for mics—clear voice pickup during calls/podcasts, reduces background noise.
- Battery Life: Up to 7.5 hours per charge (music use), extending to 30 hours total with the compact charging case. Fast charging: 15 minutes = 120 minutes playback. USB-C charging.
- Other Specs: Bluetooth 5.4 for stable, low-latency connection; IPX5 sweat/water resistance (great for workouts/rain); smart touch controls (play/pause, skip, calls, volume); no dedicated app needed (simple plug-and-play).
