OnePlus Buds 4 Wireless Earbuds - Balanced Sound with ANC

In this review the OnePlus Buds 4 are assessed as a strong option for listeners who want studio-style audio and effective noise handling without a high price tag. The biggest reason to consider these earbuds is their combination of 11mm drivers with Hi-Res Audio and LHDC 5.0 support, which delivers a clear, balanced soundstage rarely found in this segment. They also pair useful long-run battery life and smart noise control into a compact in-ear design, making them a practical daily driver for commuting, calls, and entertainment.

Key Features

• Premium sound: 11mm audio drivers with Hi-Res Audio and LHDC 5.0 provide detailed, balanced reproduction across lows, mids and highs for a studio-grade listening experience.
• Advanced ANC: Industry-leading active noise cancellation uses swift processing to reduce ambient noise for clearer listening in noisy environments.
• Adaptive Mode: An intelligent system automatically switches between noise cancellation and transparency so voices and alerts pass through when needed.
• Long battery life: The buds and the 530mAh charging case deliver over 24 hours of combined playback for extended use away from a charger.
• Seamless connectivity: Bluetooth 5.4 ensures a stable wireless connection for music, calls, gaming and video with minimal dropouts.

Who It's For

The OnePlus Buds 4 suit listeners who prioritize sound quality and adaptive noise control on a budget-conscious purchase; audiophiles who want clear, detailed playback and those who commute will appreciate the ANC and Adaptive Mode. They are also a good fit for users who need dependable connectivity and multi-hour battery life for long daily use.

Those who should look elsewhere include users demanding maximum battery endurance for multi-day use without charging, or people who prefer over-ear headphones for passive isolation. Also consider alternative models if you require advanced app-based customization beyond the core listening and ANC features.
