The OnePlus 6 may not be the only major new product that OnePlus is working on.
A Bluetooth product certification page has been spotted that mentions a pair of wireless headphones made by OnePlus. Called "OnePlus Bullets Wireless", the model number for these headphones is BT31B.
Unfortunately, there aren't really any details about these wireless headphones contained within the listing. It's unclear what they'll look like or whether they'll be truly wireless earbuds or if the two buds will be connected by a wire.
There are already a number of companies that've gotten into the wireless headphone game, including Apple, Samsung, and Huawei, so it's no surprise that OnePlus would want to get in on the action, too. OnePlus has a history with headphones but they've been wired, so it'll be interesting to hear how the company's wireless headphones perform.
