OnePlus is gearing up to reveal a new smartphone dubbed OnePlus Nord on July 21. It will be an important event for the company, after all, the last mid-range phone that we saw from the company was the ill-fated OnePlus X. Besides the OnePlus Nord, the company will announce its first TWS earphones, for now, being called OnePlus Buds. Today, the Chinese company published a new teaser. The new bit is about the noise-canceling feature, however, it might not be what you are expecting.
