OnePlus Buds 4

OnePlus Buds 4 — Pro Performance. Accessible Price.

OnePlus built its reputation on delivering flagship specs at honest prices. The OnePlus Buds 4 continues that tradition — bringing dual-driver dual-DAC architecture, 55dB ANC, and LHDC 5.0 to a price bracket where most competitors are still stuck with single drivers and standard codecs.

🎵 Dual Drivers + Dual DAC — Audiophile Hardware in an Everyday Earbud

The Buds 4 combines a 10.4mm composite dynamic woofer and a 6mm planar diaphragm tweeter, each powered by its own dedicated DAC (Digital-to-Analog Converter). Why does this matter? Two separate DACs eliminate crosstalk between drivers, reduce electrical interference, and allow each driver to render its frequency range with maximum clarity. The bass hits deeper without bleeding into vocals. The highs stay crisp without harshness. The result is a layered, detailed, and genuinely premium sound that earbuds at this price simply don’t usually deliver.

🔇 55dB Adaptive ANC — Best-in-Class Noise Cancellation

OnePlus claims up to 55dB of adaptive noise cancellation that recalibrates up to 800 times per second — a hardware spec that matches or exceeds earbuds costing three times more. In real-world use, this translates to effective suppression of traffic rumble, air-conditioning hum, office chatter, and campus noise. Multiple ANC levels (Max, Moderate, Mild) let you dial in the right amount for your environment.

📡 LHDC 5.0 — Hi-Res Audio at 192kHz

The Buds 4 supports LHDC 5.0 — the latest generation of the Hi-Res Bluetooth codec, capable of streaming at up to 192kHz sampling rate. On compatible OnePlus, Oppo, Realme, or Xiaomi devices, this unlocks studio-quality wireless audio with noticeably more depth, air, and detail than standard AAC or SBC connections.

🎮 47ms Gaming Mode + AI Translation

Activate Game Mode for 47ms ultra-low latency — keeping audio perfectly synced in competitive titles like Free Fire or BGMI. The Buds 4 also features AI Translation mode for real-time multilingual conversations — a genuinely futuristic feature that works on select OnePlus devices.

🌐 3D Audio + Golden Sound

OnePlus 3D Audio creates a wider, more spatial soundstage — music sounds like it’s around you rather than inside your head. The Golden Sound feature runs a hearing test and generates a personalised EQ curve calibrated to your ears — one of the most thoughtful audio customisation features at any price point.

🔋 44-Hour Battery + BassWave EQ

Up to 10 hours per charge (ANC off) and 44 hours total with the case. The BassWave slider lets you independently adjust bass depth — add extra rumble for electronic music, or dial it back for studio-accurate listening.
