OnePlus has launched the Nord Buds 4 Pro in India, expanding its Nord audio lineup. The new true wireless earbuds bring upgrades in noise cancellation, connectivity, and AI-backed features. They support up to 55dB Active Noise Cancellation with a bandwidth of up to 5000Hz, along with the LHDC 5.0 Hi-Res codec and Bluetooth 6.0. Features such as dual device connection and Google Fast Pair are also included.

The earbuds feature 12mm titanium-coated dynamic drivers and come equipped with six microphones, three in each bud, for AI-based call noise cancellation. They also include a transparency mode. The design has been updated with an oval-shaped vertical charging case, replacing the pebble-style case from earlier models. OnePlus claims the case size is reduced by over 10 percent. Each earbud weighs 4.4g and comes with IP55-rated protection against dust, sweat, and water.

Touch controls allow users to manage playback, calls, and voice assistants. Slide gestures for volume control are now supported. The earbuds also integrate AI features, including voice assistant access, alarms, reminders, weather updates, and general queries. When paired with select OnePlus devices running OxygenOS 15.0.1 or later, the earbuds support real-time translation across languages such as English, Hindi, Spanish, and French via the HeyMelody app. A future update will enable recording and translating audio on compatible devices.
Battery performance is a key highlight. The Nord Buds 4 Pro offer up to 13 hours of playback on the earbuds without ANC and up to 54 hours total with the charging case. With ANC enabled using LHDC, users can get up to 7 hours on the earbuds and 26 hours combined. Fast charging support provides up to 13 hours of playback with just 10 minutes of charging.
The earbuds pack a 62mAh battery in each bud and a 530mAh battery in the case. They are priced at Rs. 3,999 (~$42.88) and come in Radiant Gray and Raven Black. Sales begin on March 23 across online and offline platforms, with a limited-time launch price of Rs. 3,799.
