The OnePlus Nord Buds 3 Pro follow a true wireless, cable-free design with an in-ear fit and weigh just 8.8 g per earbud, keeping them light and unobtrusive during use. They carry an IP55 rating, meaning they are resistant to sweat and the kind of moisture exposure typical during physical activity. Each earbud houses a stereo speaker, while features such as wingtips, RGB lighting, a display, and UV light are not included. The overall form factor is compact and straightforward, with no neckband connecting the two earbuds.
The OnePlus Nord Buds 3 Pro are equipped with a 12.4 mm driver unit and cover a frequency range from 20 Hz up to 40,000 Hz, giving them a wide audible spectrum. Both active noise cancellation and passive noise reduction are supported, helping to limit unwanted ambient sound in different listening situations. Spatial audio is also available, adding a sense of dimensional depth to compatible content. Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the specification for these earbuds.
Each earbud carries a 58 mAh rechargeable battery rated for 12 hours of playback, which drops to 5.5 hours when active noise cancellation is in use. The charging case holds a 440 mAh battery and extends total listening time to 32 hours combined. A full charge takes 2 hours, and a battery level indicator is included so users can monitor remaining power. Wireless charging and solar battery functionality are not supported.
The OnePlus Nord Buds 3 Pro connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m, and fast pairing is supported for quicker device setup. The AAC codec is available for audio transmission, while LDAC, LDHC, aptX in all its variants, LE Audio, and Auracast are not supported. Audio latency is rated at 96 ms, and NFC pairing is not included. The charging case uses a USB Type-C connection, keeping the setup in line with current wired charging standards.
The OnePlus Nord Buds 3 Pro include a practical set of features for daily use, starting with ambient sound mode, in-ear detection for automatic playback pausing, and a find device function. Multipoint connectivity supports simultaneous pairing with up to two devices, and fast charging is available to reduce downtime. The earbuds can function as a headset for calls, include a mute function, and provide voice prompts along with a control panel on the device itself. A travel bag is included in the box. Notification readout, a built-in translator, an in-line control panel, a body temperature sensor, and a camera remote shutter are not part of the feature set.
