Alongside the latest Nord smartphones, OnePlus has also introduced the OnePlus Buds 4, rounding out a value-focused ecosystem for users seeking solid performance without breaking the bank. The OnePlus Buds 4 comes with a dual-driver setup in each earbud, featuring an 11mm woofer and a 6mm tweeter, each powered by independent dual DACs for richer sound separation.

On the noise cancellation front, the buds feature Real-time Adaptive ANC, capable of reducing noise by up to 55dB across a 5500Hz range, with the system automatically adjusting ANC levels up to 800 times per second based on your surroundings, as per OnePlus. There's also a new Adaptive Mode, which balances noise cancellation and environmental awareness. Voice clarity gets a major upgrade too, with 200% improved voice filtering over the previous generation.
The OnePlus Buds 4 supports the LHDC 5.0 codec and carries Hi-Res Wireless Audio certification, with extras like OnePlus 3D Audio and Golden Sound personalisation enhancing the experience on supported devices.
Each bud houses a three-mic system paired with AI-powered noise cancellation to improve call clarity, while the lightweight design makes them comfortable for all-day wear. Touch controls come built-in for playback and call management.
Connectivity includes Steady Connect for stronger Bluetooth performance in open spaces, AI-powered live translation, and support for native voice assistants. You also get Google Fast Pair and Dual-Device Connection for easy switching between devices.
Gamers will appreciate the 47ms low-latency Game Mode, while battery life stretches up to 11 hours on a single charge (buds only) and up to 45 hours with the case (ANC off). A quick 10-minute top-up gives you around 11 hours of total use. The Buds 4 are also IP55-rated for water and dust resistance and certified by TÜV Rheinland for battery reliability across 1,000 charging cycles.
They come in Zen Green and Storm Grey, priced at ₹5,999 in India.
