OnePlus Buds 3 — Hi-Res Sound, Adaptive Noise Cancellation, All Day Battery.

The OnePlus Buds 3 slots between the budget Nord Buds and the flagship Pro series, bringing dual drivers, LHDC 5.0 Hi-Res audio, and 49dB ANC to a mid-range price. If you want genuine premium audio without spending flagship money, the Buds 3 is one of the best-rounded earbuds in its class.

🎵 Dual Dynamic Drivers + BassWave

Two drivers work in perfect harmony inside each earbud — a 10.4mm TPU woofer for deep, vibrant bass and a 6mm tweeter for clean, detailed highs and forward vocals. The woofer’s dual-layer TPU material adds bass vibrancy and rumble you can physically feel on bass-heavy tracks. The BassWave slider in the app lets you adjust bass depth from -5 to +5 — dial in your exact preference.

🔇 49dB Adaptive ANC

With up to 49dB of adaptive noise cancellation, the Buds 3 handles commutes, study sessions, and office environments impressively well. Choose from Max, Moderate, or Mild ANC modes — or let Smart ANC automatically select the right level. Transparency Mode passes ambient sound through naturally for conversations without removing the earbuds.

📡 LHDC 5.0 — Certified Hi-Res Wireless Audio

The Buds 3 is Hi-Res Audio Wireless certified with LHDC 5.0 support. Connect to a compatible OnePlus, Oppo, or Realme device and unlock audio detail that standard AAC simply can’t reproduce — every layer of a complex mix rendered with precision and depth.

🎛️ Stem Volume Controls + Multi-Point

Slide up or down on either earbud’s stem to raise or lower volume — no more reaching for your phone just to adjust audio. Multi-point connection keeps the Buds 3 paired to two devices simultaneously with seamless, automatic switching. Stellar multi-device management that routinely outperforms much pricier competitors.

🔋 44-Hour Battery

Up to 10 hours per charge (ANC off) and a total of 44 hours with the case. The Buds 3 gives you a full working week of daily use before you need to look for a charger.

📱 HeyMelody App + Golden Sound

Works with any Android or iOS device via the HeyMelody app. Key features include: personalized Golden Sound audio profile (hearing test-based EQ), 5 Dynaudio-inspired EQ presets, custom EQ, ANC controls, BassWave, and firmware updates.
