OPPO Enco Air2 True Wireless Earphones In-Ear Type for iPhone Android iPad Unlike the Pro version, it does not have noise-canceling functionality. Both earbuds have been tested for sound, earbud sensor, and charging. It was at 90% when fully charged, so there may be some battery degradation. I have wiped it with alcohol, but some minor dirt remains. A charging cable (type-C) is not included.
