Hi-Res Wireless Audio with LDAC
The QCY Crossky C30S brings high-quality wireless listening to an open-ear form factor with support for Hi-Res Wireless Audio and LDAC technology. LDAC is designed to transmit substantially more audio information than conventional Bluetooth codecs when used with compatible devices and high-quality audio sources. Combined with QCY’s audio processing, this allows users to experience greater musical detail, improved clarity, and a more engaging sound signature across music, movies, podcasts, and other entertainment.
10.8mm Dual-Magnet Bio-Diaphragm Driver
At the heart of the Crossky C30S is a powerful 10.8mm dual-magnet bio-diaphragm driver engineered to deliver rich and detailed sound from its compact open-ear construction. The driver is designed to reproduce crisp high frequencies, full-bodied mids, and powerful bass. A dedicated bass enhancement algorithm dynamically improves low-frequency performance while helping reduce unwanted high-frequency distortion, creating a more balanced listening experience across different volume levels and music genres.
360° Spatial Sound & Directional Audio
The QCY Crossky C30S incorporates 360° Spatial Sound technology powered by QCY’s spatial audio algorithm to produce a wider and more multidimensional soundstage. This can make music, movies, and gaming content feel more immersive despite the headphones’ open-ear construction. Advanced directional audio technology precisely directs sound toward the listener while auto-adjusting sound beams help minimize unwanted sound leakage, providing a more focused and private listening experience.
Secure & Comfortable Open-Ear Clip Design
Designed for extended everyday use, the Crossky C30S features an innovative open-ear clip structure with an asymmetrical 12° design for improved balance and a more secure fit. The ear clips use flexible Ni-Ti memory alloy combined with a soft silicone finish, allowing them to adapt comfortably to different ear shapes. Because the ear canal remains open, users can maintain greater awareness of their surroundings while listening, making the C30S suitable for running, cycling, commuting, workouts, and long listening sessions.
Bluetooth 6.0, 60ms Low Latency & Multipoint
The QCY Crossky C30S features the latest Bluetooth 6.0 connectivity for a fast, stable, and efficient wireless connection. Its ultra-low latency can reach approximately 60ms, helping maintain better synchronization between audio and visual content during gaming and video playback. The headphones also support Dual-Device Multipoint Connection, allowing users to stay connected to two compatible Bluetooth devices and conveniently switch between a smartphone, laptop, tablet, or other connected device.
40-Hour Battery, Fast Charging & IPX5
Battery performance is another major advantage of the Crossky C30S. The headphones provide approximately 6 hours of playback from the earbuds, while the charging case extends total listening time to around 40 hours. Fast charging support provides approximately 1 hour of listening from only 10 minutes of charging, making quick top-ups convenient. An IPX5 water-resistance rating provides additional protection against sweat and light rain, making the headphones suitable for workouts and outdoor activities.
