OnePlus Buds 4

OnePlus Buds 4 — Studio sound. Real-world quiet. All day long.

The OnePlus Buds 4 are built for people who don't compromise — flagship-grade audio, adaptive noise cancellation that reads the room, and a battery that outlasts your day. Engineered for the commute, the gym, the call, and everything in between.

Hear everything, mixed exactly as the artist intended.

A true dual-driver system pairs an 11mm woofer with a 6mm tweeter, each fed by its own dedicated DAC. The result: deep, controlled bass and crisp, detailed highs across a wide 15Hz–40kHz soundstage. With LHDC 5.0 Hi-Res audio (up to 24-bit/192kHz), the Buds 4 deliver near-lossless detail most earbuds throw away.

Silence on demand — up to 55dB of it.

Real-time Adaptive Active Noise Cancellation measures your surroundings and adjusts up to 800 times per second, cancelling up to 55dB across a 5,500Hz range. Step outside and Adaptive Mode blends in just enough of the world to keep you aware and safe — no tapping required. Prefer manual? Switch freely between ANC, Transparency, and Adaptive with a long press.

Calls that actually sound like you.

Three microphones per earbud plus AI call noise reduction strip out wind, traffic, and background chatter — so every word lands clearly, even on a busy street.

A full day, then some.

Up to 45 hours total playback with the charging case, and 11 hours on a single charge. In a rush? A 10-minute quick charge delivers up to 11 hours of music. Bluetooth 5.4 with Steady Connect keeps your audio locked in and stutter-free, indoors or out.

Built for play, ready for anything.

A 47ms low-latency game mode keeps every footstep and gunshot perfectly in sync with the action. Dual-device connection keeps you paired to your phone and laptop at once — switch instantly, no re-pairing. And with IP55 dust and water resistance, sweat and rain are no problem.

Control at your fingertips.

• Slide up / down — volume
• Single tap — play / pause
• Double / triple tap — skip tracks
• Long press — switch noise modes

Plus Google Fast Pair for one-tap setup, a voice assistant shortcut, Find My Earbuds, real-time AI Translation, and OTA updates that keep adding features over time.
