Who Are the OnePlus Buds 4 For?
Based on the published specifications, the Buds 4 are particularly feature-focused around audio quality, adaptive ANC, wireless connectivity, gaming latency and long playback.
OnePlus Buds 4 Review Verdict
The OnePlus Buds 4 are built around a feature-rich audio platform. Their 11mm woofer and 6mm tweeter are paired with dedicated DACs, while LHDC 5.0 adds support for high-resolution wireless audio on compatible devices.
Noise cancellation is another major focus. OnePlus specifies real-time adaptive ANC up to 55dB, with adjustments made up to 800 times per second. Adaptive and Transparency modes provide alternatives when users need more awareness of their surroundings.
Battery endurance is rated at up to 45 hours for the earbuds and case together when using AAC with ANC off. Even with ANC on, OnePlus specifies up to 24 hours total playback with AAC.
Bluetooth 5.4, dual-device connection, Google Fast Pair, AI call noise cancellation and Find My Earbuds add useful everyday functionality. Gamers also get a published 47ms low-latency Game Mode figure under laboratory conditions.
The main feature limitations to keep in mind are that IP55 protection applies only to the earbuds, some Hi-Res features require compatible devices, and actual ANC, battery and latency performance varies with real-world conditions.
