Hi-Res Wireless Audio with LDAC
The QCY Crossky C50i is designed for users who want better sound quality without sacrificing the comfort and environmental awareness of an open-ear design. It supports Hi-Res Wireless Audio and the LDAC codec, allowing compatible devices to transmit significantly more audio information than conventional Bluetooth playback. QCY states that LDAC can provide up to three times more sonic detail compared with standard Bluetooth audio under suitable conditions. This helps reproduce richer musical textures, clearer vocals, and more detailed instruments for an enhanced everyday listening experience.
12mm Composite Dynamic Driver
At the heart of the Crossky C50i is a custom 12mm Composite Dynamic Driver engineered specifically to deliver rich and engaging sound from its open-ear structure. The larger driver helps generate powerful low-frequency response while maintaining detailed mids and clear high frequencies. Whether listening to energetic music, podcasts, movies, or other entertainment, the driver provides a balanced combination of bass impact and clarity. The open-ear configuration also keeps the ear canal unobstructed, allowing users to remain aware of important surrounding sounds.
Ergonomic C-Bridge Open-Ear Design
Comfort is a major focus of the Crossky C50i. Its ergonomic C-Bridge design uses an approximately 0.5mm ultra-slim memory alloy frame combined with an extended outward-curved soft bridge. The flexible structure is designed to accommodate a wider variety of ear shapes while providing a secure clip-on fit. Because the earbuds do not need to be inserted deeply into the ear canal, they can reduce the pressure associated with conventional in-ear designs and provide a comfortable option for long listening sessions, workouts, commuting, and daily activities.
4-Mic ClearVoice Call Technology
The QCY Crossky C50i incorporates a 4-Microphone ClearVoice system, using microphones across both earbuds to improve voice communication. QCY combines the microphone system with an ergonomically optimized directional design to capture the user’s voice more effectively while minimizing unwanted sound leakage and environmental interference. This makes the C50i useful for regular phone conversations, online meetings, and voice communication while commuting or working. The open-ear construction also allows users to remain naturally aware of their surroundings during conversations.
42-Hour Battery with Fast Charging
Battery endurance is designed to comfortably support everyday use. The Crossky C50i provides up to 8 hours of playback on a single charge, while its 500mAh charging case extends total battery life to approximately 42 hours under specified conditions. Each earbud incorporates a 40mAh battery. Fast charging adds further convenience, with approximately 10 minutes of charging providing up to 1.5 hours of playback. A modern USB Type-C interface is provided for recharging the case, making it easy to use commonly available charging accessories.
Bluetooth 6.0, Dual Connection & QCY App
Modern Bluetooth 6.0 provides stable wireless connectivity with an operating range of approximately 10 meters. The Crossky C50i also supports Dual Connection, allowing two compatible devices to remain connected simultaneously for easier switching between a smartphone, tablet, laptop, or other devices. Through the QCY App, users can access EQ customization, battery information, Find My Earbuds, control customization, firmware upgrades, and other supported functions. A dedicated Game Mode provides lower latency, while IPX5 water resistance offers useful protection against sweat and splashes during active everyday use.
