Description
Everyday true wireless listening
OnePlus Buds 4 are lightweight in-ear earbuds with on-bud touch controls, voice assistant access, and a pocketable charging case. Pair quickly over Bluetooth, optionally use Google Fast Pair, and switch between two paired devices when you need dual-device connection. A low-latency audio option helps keep video and games in sync.
Driver layout and tuning
Each bud uses an 11 mm woofer plus a 6 mm tweeter. Frequency response spans 15 Hz–40 kHz with driver sensitivity 118±1.3 dB @ 1 mW, sound pressure 96.5 dB, and impedance 18 Ω ± 15% / 10 Ω ± 15%. Codecs include LHDC 5.0, AAC, and SBC.
Active noise control and calls
Real-Time Adaptive Active Noise Cancellation reduces noise by up to 55 dB across frequencies up to 5,500 Hz. Choose ANC on, Adaptive Mode, Transparency Mode, or ANC off. Three microphones per side (-38±1 dB sensitivity) work with 3-mic AI call noise cancellation for clearer conversations.
Wireless link
Bluetooth 5.4 with Steady Connect; effective distance about 10 m. Profiles: HFP, A2DP, AVRCP.
