OnePlus Buds 4 Wireless Earbuds, Storm Grey

The OnePlus Buds 4 are true wireless earbuds featuring a dual-driver system with an 11 mm primary driver, designed for a detailed audio response. The acoustic system is closed-back and engineered to support a wide frequency range from 15 Hz to 40,000 Hz. Connectivity is established through Bluetooth 5.4, supporting LHDC 5.0, AAC, and SBC codecs for high-resolution audio streaming on compatible devices. The in-ear, canal-style fit provides passive noise isolation.

These earbuds incorporate Adaptive Active Noise Cancellation, which is rated to reduce ambient sound by up to 55 dB. For voice calls, the system uses a three-microphone array with noise-canceling technology to isolate the user's voice. The earbuds provide up to 11 hours of playback on a single charge, with the included charging case extending the total time to 45 hours. A 10-minute fast charge via the USB-C port provides additional listening time. The enclosures are rated IP55 for resistance to dust and water splashes, and playback is managed through gesture controls.
