QCY Crossky C30S Open-Ear Headphones

Experience high-resolution wireless sound without blocking your surroundings with the QCY Crossky C30S Open-Ear Headphones. Featuring Hi-Res Wireless Audio with LDAC, a 10.8mm dual-magnet dynamic driver, Bluetooth 6.0, immersive 360° spatial sound, and up to 40 hours of total battery life, the Crossky C30S is designed for music, calls, exercise, commuting, travel, and everyday use.

Comfortable Open-Ear Clip Design

The QCY Crossky C30S uses an open-ear clip-on design that rests outside the ear canal rather than sealing it. This allows you to enjoy your music while remaining more aware of traffic, announcements, conversations, and other surrounding sounds.

Its secure, lightweight construction is suitable for extended use during walking, office work, commuting, workouts, and outdoor activities.

Hi-Res Audio with LDAC

Enjoy richer detail and greater clarity with Hi-Res Wireless Audio certification and LDAC codec support. When paired with a compatible device and high-quality audio source, LDAC can transmit more audio information than standard Bluetooth codecs.

This helps reproduce clearer vocals, more detailed instruments, and a more immersive listening experience across music, movies, podcasts, and games.

10.8mm Dual-Magnet Dynamic Driver

The QCY Crossky C30S features a 10.8mm dual-magnet bio-diaphragm dynamic driver. Combined with QCY’s bass-enhancement algorithm, the driver is designed to produce stronger bass, clear mids, and detailed high frequencies.

The result is a balanced sound profile suitable for multiple genres of music and everyday entertainment.

Immersive 360° Spatial Sound

The built-in 360° spatial sound technology creates a wider and more immersive audio environment. It adds a greater sense of space and direction to music, movies, and gaming content.

This feature helps make the listening experience feel more open and engaging than conventional stereo playback.

Bluetooth 6.0 Connectivity

Bluetooth 6.0 delivers faster pairing, stable wireless transmission, and improved connection efficiency with compatible smartphones, tablets, and computers.

The Crossky C30S supports Android and iOS devices and is suitable for music streaming, calls, video playback, and everyday entertainment.

Dual-Device Connection

Dual-device connectivity allows the QCY Crossky C30S to remain connected to two compatible devices simultaneously.

This makes it easier to switch between a smartphone, laptop, or tablet without repeatedly disconnecting and pairing the headphones. Only one connected device can play audio at a time.

Up to 40 Hours of Battery Life

The QCY Crossky C30S provides up to 6 hours of playback on a single charge, while the charging case extends total battery life to up to 40 hours.

Actual playback time may vary depending on volume, codec, connection conditions, and usage habits. Wireless charging support and conventional cable charging offer convenient ways to recharge the case.

IPX5 Water Resistance

The IPX5 water-resistance rating helps protect the headphones against sweat, light rain, and everyday splashes.

This makes the Crossky C30S suitable for jogging, gym sessions, commuting, walking, and regular outdoor use. It should not be submerged in water or used while swimming.

QCY App Support

The QCY App allows users to access compatible customization options such as EQ settings, touch controls, firmware updates, and additional device functions.

This gives you more control over the sound and everyday operation of the Crossky C30S.
