Sound That Moves With You

The QCY Crossky C50 redefines what it means to wear earbuds all day. Engineered with an ultra-light, open-ear clip-on design, these earbuds rest effortlessly on your ear — so weightless, so natural, you'll forget they're there. Whether you're deep in a morning run, navigating a busy commute, or settling into a long work session, the C50 delivers rich, immersive audio without ever compromising your awareness of the world around you. This is sound designed for real life.

Powered by dual-magnet drivers and carbon-fiber diaphragms, the C50 produces deep, resonant bass that reaches down to 20Hz — every beat felt as much as heard. The built-in bass enhancement algorithm and dynamic EQ ensure balanced, powerful audio at any volume. Four precision microphones with beamforming AI filter out wind and ambient noise, so your calls come through with remarkable clarity. And with Bluetooth 6.0, you get a faster, more stable connection with ultra-low latency across all your devices.

Built for those who refuse to compromise, the C50 offers up to 35 hours of total playback, IPX5 sweat and splash resistance, and intuitive touch controls. Adaptive volume automatically adjusts to your surroundings, while auto left-right correction means you never have to think about which earbud goes where. Available in White, Pink, and Black — the C50 is as refined in style as it is in performance.

FAQ:

Q: What should I do if the headset received is unable to turn on?

A: Confirm that the charging case has power left, press the button on the case and check if at least one LED is illuminated. If the charging case is depleted, place the earphones in the case and charge for 1 hour. Before charging, remove any stickers on new earphones. Connect the case with the included USB cable and plug into a USB power source.

Q: What should I do if sound comes from only one earphone?

A: Place both earphones back into the charging case, close the cover, then take them out again. If only one earphone still has sound, restore factory settings for both earphones.

Q: How to solve a connection issue on my phone?

A: Delete the pairing record on your phone, then search and pair again.

Q: No sound during music or calls?

A: On Android, find the settings icon next to the Bluetooth connection name, toggle off then on the phone audio and media audio. If the issue persists, re-pair the earphones.

Q: Why is there a delay in video or games?

A: Delays can occur due to the environment, network conditions, or your phone's codec. This is normal Bluetooth behaviour.

Q: How to fix stuck or intermittent sound?

A: Nearby Wi-Fi, 5G/4G signals, or high-power appliances may cause interference. Try changing your environment or re-pairing the earphones.
