The Buds Z2 are OnePlus' latest TWS earbuds, although they have not been available outside China to date. The OEM has revealed that this will change in mid-December 2021 with their debut in Europe. This launch is to be a social media-centric event, although the product is also intended to boost the company's Red Cable Club expansion into a new region.
