OnePlus Buds Clip Open-Ear Wireless Earbuds Bluetooth 6.1

The OnePlus Buds Clip are open-ear wireless earbuds built for people who want great sound without feeling sealed off from the world. Each bud weighs just 5.2g and clips onto your ear with a flexible Ni-Ti arc, so you can wear them for hours at work, on a commute or during a workout.

These oneplus earbuds pair an 11mm woofer with a 9mm tweeter, co-created with Dynaudio, and support Hi-Res Audio through LHDC 5.0. Six microphones with AI Bone Call technology keep your voice clear on calls, even in noisy places.

With Bluetooth 6.1, dual-device connection and up to 40 hours of total playtime with the case, they suit daily commuting, sports, study and long workdays.

Key Features

• Clip-on open-ear design with flexible Ni-Ti arc: The arc holds the earbud gently in place without sitting inside the ear canal, so you stay aware of traffic, announcements and people around you.
• Ultra-lightweight 5.2g per earbud: The low weight reduces ear fatigue, so you can wear them comfortably for long sessions.
• Either-ear symmetry with automatic left/right detection: Wear either bud in either ear and the audio channels adjust automatically, so there is no fumbling to get them on correctly.
• 11mm woofer and 9mm tweeter, co-created with Dynaudio: The dual-driver setup gives deeper bass and clearer highs for music, podcasts and videos.
• Hi-Res Audio with LHDC 5.0 and Dual DACs: Compatible devices can stream higher-quality audio with more detail than standard Bluetooth codecs.
• 6nm AI Audio Chip: Faster, more efficient audio processing supports clearer sound and smoother performance.
• 6-mic AI Bone Call technology: Two MEMS mics and one VPU per bud, with bone conduction, pick up your voice clearly for calls and online meetings.
• Bluetooth 6.1 with dual-device multipoint connection: Stay connected to your phone and laptop at once and switch between them without re-pairing.
• Up to 9.5 hours of playtime, 40 hours with the case: One charge lasts through a full day of use, and the case adds long-term backup.
• IP55 dust and water resistance: Sweat, light rain and dusty conditions are no problem for sports and outdoor use.
• Smart AI Translate and Drop Monitor alerts (with compatible devices): Helpful extras for conversations across languages and for keeping track of your earbuds.

Why Choose the OnePlus Buds Clip Open-Ear Wireless Earbuds

IP55 protection adds confidence for gym sessions and outdoor activities, and the either-ear design makes them quick to put on.
