QCY Crossky C30S Red bluetooth headset

Open-Ear Clip Design

The QCY Crossky C30S is a pair of open-ear Bluetooth headsets that use a nickel-titanium alloy clip to sit securely on the ear without entering the canal. Each earbud weighs less than 5g, providing a pressure-free fit for long workouts, runs or daily commutes. The ergonomic anti-Z-shaped frame adapts to different ear shapes so the buds stay in place during movement. This design keeps the ear canal open for ambient awareness while delivering audio.

Bluetooth 6.0 Dual Connectivity

The headset uses Bluetooth 6.0 for a stable, fast link and can maintain simultaneous connections with two devices. You can listen to audio from one source while staying ready for calls on the other without manual switching. Directional Audio 3.0 combined with reverse soundwave cancellation reduces sound leakage by 99.5 percent, preserving privacy in shared spaces. An AI-powered microphone and wind-blocking structure keep voice transmission clear outdoors.

40-Hour Battery & IPX5

The charging case holds 460mAh and provides up to 40 hours of total playtime, with 6 hours available from a single charge of the earbuds. A 10-minute USB-C quick charge adds roughly 1 hour of listening time for short-notice sessions. IPX5 rating protects the earbuds against sweat, light rain and splashes during intense training. The 10.8mm dual-magnet drivers with carbon fibre diaphragms support LDAC and 96kHz/24bit Hi-Res Audio, while dynamic tuning at 48,000 times per second shapes a 360-degree spatial soundstage.
