With a couple of generations of wireless earbuds under its belt, OnePlus finally has the AirPods Pro — and the rest of the premium market — in its sights. As part of an event today that also includes the launch of its budget Nord 2, the company officially announced the OnePlus Buds Pro.

The top-line feature here is adaptive noise canceling, which uses a trio of on-board mics to filter out ambient sound up to 40 dBs. The company says the tech compares favorably to more standard active noise cancelling, which offers a set level of filtering. The buds are powered by a pair of 11mm dynamic drivers, with support for Dolby Atmos.
