Wireless headphones QCY Crossky Clip C30S (black) — clip-on design, model T33S

The QCY Crossky Clip C30S earphones (black) are open-ear headphones designed to let you listen to music while remaining aware of your surroundings. The open-ear form with an Anti‑Z clip reduces pressure and discomfort for extended wear. A 10.8 mm dual‑magnet driver combined with a Bass Enhancement algorithm delivers clear, deep sound, while LDAC support and Hi‑Res Audio Wireless certification provide higher detail and spatial clarity. Bluetooth 6.0 ensures a stable connection and the combined battery life reaches up to 40 hours with the charging case.

Advantages

The lightweight open-ear construction keeps ears free and maintains environmental awareness, suitable for running, cycling and daily use. Shape‑memory Ni‑Ti alloy and a soft silicone finish adapt to the ear for comfortable long-term wear, and IPX5 protection guards against sweat and splashes. Advanced audio technologies (LDAC, Hi‑Res Wireless, Bass Enhancement) deliver detailed sound and controlled bass, while AI-assisted microphones and Wind‑Blocking design improve voice clarity during calls. Fast Bluetooth 6.0 pairing and dual‑device connection enable reliable low‑latency performance across two devices.

Pair the earphones via Bluetooth 6.0 from your device settings; use the Dual‑Device Connection feature to connect two devices simultaneously. Control playback, calls and voice assistant through the touchpad on the earpieces. Use the QCY app to adjust EQ, touch controls and update firmware. Charge the earphones in the case via the USB‑C port; a full earphone charge provides about 6 hours of playback and the case extends total runtime to around 40 hours. A 10‑minute quick charge adds approximately one hour of playback.

Recommendations

For outdoor activity, use the open‑ear design to stay aware of traffic and surroundings. Clean the earphones and charging contacts regularly and keep firmware updated via the QCY app to ensure optimal performance and call clarity.
