OnePlus Buds 4 Bluetooth Wireless Earbuds - Clear Hi-Res Sound

In this review the OnePlus Buds 4 are presented as a strong choice for listeners who want a balance of detailed audio and effective noise control without a premium price tag. The biggest reason to buy is the combination of an 11mm driver and LHDC 5.0 support that delivers noticeably better clarity and detail than many mainstream true wireless earbuds in this segment, while the Adaptive Mode for ANC and Transparency makes them easier to live with day to day. For commuters and casual audiophiles the Buds 4 hit a practical sweet spot.

Key Features

• 11mm audio drivers: deliver balanced, true-to-life acoustics that reveal clearer mids and satisfying bass for most musical genres.
• Hi-Res audio with LHDC 5.0: preserves more detail over Bluetooth so instruments and vocals sound distinct and studio-like on supported devices.
• Advanced ANC: industry-leading active noise cancellation reduces background noise quickly, improving focus on music or calls in busy environments.
• Adaptive Mode: intelligently switches between ANC and Transparency modes so users get situational awareness without fiddling with settings.
• Bluetooth 5.4 connectivity: provides stable wireless performance and fewer dropouts during everyday use.
• 530mAh charging case: offers extended playback time with convenient USB-C charging for multi-day portability.

Who It's For

The OnePlus Buds 4 suit commuters, remote workers, and mobile listeners who want enhanced audio detail and a capable active noise cancellation system without stepping up to flagship prices. The combination of Hi-Res LHDC support and 11mm drivers makes them appealing to users who value sound clarity for podcasts, streamed music, and on-device audio.

Those who should look elsewhere include users who need industry-leading battery runtimes or the absolute smallest earbud shells for very small ears, as customer feedback on battery life and build perception is mixed. Also, people locked into codecs that do not support LHDC may not get the full Hi-Res benefit.
