Key Features of OnePlus Buds 4 TWS Earbuds

The OnePlus Buds 4 TWS Earbuds come packed with an 11mm woofer and a 6mm tweeter in each bud, giving you a richer, fuller soundstage. That means deep bass, crisp highs, and perfectly balanced mids exactly what you'd expect from OnePlus.

Smarter Noise Cancellation, Smarter Listening

Need to shut out the noise? OnePlus Buds 4’s adaptive noise cancellation (ANC) adjusts in real-time to your surroundings. With three high-quality microphones on each earbud, your voice comes through sharp and clear, even in a bustling street or busy café. Want to stay aware? Switch to Transparency Mode in a tap and hear the world around you without removing the buds.

Battery Life with Fast Charging

The OnePlus Buds 4 TWS Earbuds are built to keep up with your day. Listen for up to 45 hours with the charging case when ANC is off. Even with ANC on, you're still getting a reliable 24 hours of playback more than enough for a weekend away or back-to-back meetings. In a rush? A 10-minute quick charge gets you up to 11 hours of playback time. That’s right — just plug in while you get ready and you're set for the day.

Crystal-Clear Calls with Triple Mic Setup

Each bud is equipped with three precision microphones that capture your voice and reduce background noise during calls. With microphone sensitivity rated at -38±1dB and driver sensitivity at 118±1.3dB, your voice stays loud, crisp, and easy to hear — even in windy or crowded environments. Rain or shine, workout or walk — the OnePlus Buds 4 TWS Earbuds are IP55-rated for dust and water resistance. That means they’ll survive a sweaty run, light rain, or just daily wear and tear, making them the perfect everyday companion.
