QCY Crossky C30 Open-Ear Bluetooth Headphones Clip-On

QCY Crossky C30 are clip-on open-ear Bluetooth headphones that deliver secure, sweat-resistant fit, clear hands-free calls with four mics, and up to 25 hours total playtime with the charging case.

Designed for active users who want awareness of their surroundings, the Crossky C30 uses a C-shape open-ear design that rests outside the ear canal while staying snug during movement. Combining Bluetooth 5.4 dual-device pairing, an app for EQ customization, and a low-latency mode, these earphones blend convenience, sound clarity, and long battery life into a compact, fashion-forward package.

How do these open-ear earbuds stay secure during workouts?

The Crossky C30 use a C-shape clip-on form that hugs the outer ear rather than inserting into the ear canal, which reduces fatigue and improves situational awareness. The lightweight construction and matte finish help them stay put while you run, cycle, or train.

• C-shape clip-on design for stable fit without ear sealing
• Lightweight body and balanced weight distribution
• Matte texture plus glossy acoustic ball reduces slippage
• IPX4 splash resistance protects against sweat and light rain

What sound and call quality can I expect from the C30?

Sound is driven by a 10.8 mm dual-magnet high-sensitivity driver delivering clear vocals and balanced audio across genres. Four integrated microphones combine with an intelligent algorithm to focus on your voice and reduce background noise for clearer calls in busy environments.

• 10.8 mm dual-magnet drivers for enhanced clarity and dynamics
• 4-mic array plus voice-enhancing algorithm for better call pickup
• EQ presets and custom tuning via the app to tailor tone
• Low-latency mode (≈80 ms) for video and gaming sync

Can these earbuds connect to more than one device and how long does the battery last?

The Crossky C30 support Bluetooth 5.4 and dual-device connection so you can stay linked to a phone and a tablet or TV simultaneously without manual switching. Battery life extends to around 5.5 hours per earbud and up to 25 hours total with the included charging case for all-day use.

• Bluetooth 5.4 for stable, low-latency wireless performance
• Dual-connection to two devices at once (phone + tablet/TV)
• 5.5 hours per charge; up to 25 hours with charging case
• On-device battery readout and firmware updates via the app

What customization and app features are available?
