For the money, you’ll be getting one of the first pairs of wireless earbuds to utilise the latest Bluetooth version, 5.2. The connection proved rock-solid on all of the devices I tested the Enco X with and I didn’t experience any latency between audio and video. In terms of codecs, the Oppo Enco X support both SBC and AAC in addition to the niche LHDC (Low latency High Definition Codec). Oppo phones, including the Find X2 and Find X2 Pro, support LHDC, as do some Xiaomi and Huawei handsets but it isn’t something you’re going to be able to make use of as an owner of an iPhone or Samsung Galaxy device.
