🔊 Audio Performance

The OnePlus Buds 4 deliver exceptional audio through a dual-driver setup featuring an 11mm woofer with a 30-layer ceramic-metal diaphragm and a 6mm tweeter, powered by dual DACs for precise high and low-frequency tuning. This creates a balanced soundstage with punchy bass, clear mids, and crisp highs across a 15Hz–40kHz range, ideal for genres from EDM to classical. The LHDC 5.0 codec (1 Mbps, 24-bit, 192 kHz) ensures near-lossless, Hi-Res audio, surpassing the Buds 3’s 96 kHz cap, while AAC and SBC support broader compatibility.

The HeyMelody app’s Sound Master EQ offers presets (Balanced, Serenade, Bass Mode) and a six-band custom EQ with BassWave™ for deeper lows. Golden Sound personalizes audio via ear scans, tailoring profiles for fatigue-free listening. OnePlus 3D Audio adds immersive spatial sound for Android/iOS, enhancing movies and music. With 47ms low latency, gaming and videos stay synced. Though not as detailed as premium rivals, the Buds 4 offer vibrant, customizable audio for casual listeners and audiophiles alike.

Face-to-Face Translation enables seamless bilingual chats with split-screen text, ideal for travel or meetings.

Supporting dozens of languages via Bluetooth 5.4, it ensures clarity in noisy settings, though accuracy may dip with slang. This makes the OnePlus Buds 4 a smart, global-ready companion for multitasks.
