The OnePlus Nord Buds 3 use an in-ear fit and are fully true wireless, meaning there are no cables or neckband involved. Each earbud weighs just 8.4 g and delivers stereo sound without any RGB lighting or display on the housing. Protection is handled by an IP55 rating, confirming resistance to both dust and water splashes, though wingtips are not included in the package.
The Nord Buds 3 use a 12.4 mm driver that covers a frequency range of 20 Hz to 20,000 Hz and reaches a sound pressure level of 112 dB/mW. Both active noise cancellation and passive noise reduction are supported, giving the earbuds two layers of ambient sound management. Spatial audio, Dolby Atmos, and Dirac Virtuo are not available, and the driver does not use a neodymium magnet.
Each earbud holds a 58 mAh rechargeable battery rated for 12 hours of playback, while the 440 mAh charging case extends the total to 31 hours before needing a top-up. A full charge takes one hour, and a battery level indicator lets users keep track of remaining power at a glance. Wireless charging and solar charging are not supported.
The Nord Buds 3 connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m and an audio latency of 94 ms. AAC codec and fast pairing are both supported, while LDAC, LDHC, and the full aptX family — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — are not available. Bluetooth LE Audio and Auracast are also absent, and NFC pairing is not supported. The charging case uses USB Type-C for wired charging.
The Nord Buds 3 support multipoint connection for up to two devices simultaneously and can be used as a headset, with a mute function and voice prompts rounding out the call-related capabilities. Fast charging is available, and a find-device feature helps locate misplaced earbuds. Controls are handled through a panel on the device itself rather than an in-line control panel, and a travel bag is included in the box. Ambient sound mode, in/on-ear detection, notification reading, a body temperature sensor, and a camera remote shutter function are all absent.
The Nord Buds 3 feature a four-microphone array with noise-canceling capability, helping to reduce background interference during calls and voice input.
