Just saw this topic. I have an iPhone 7 with iOS 14.1 paired with Rexton Adore Li HAs. Over the past few months (and currently), I have experienced switching between left only and full hearing, static, and complete loss of sound/connection. This occurs primarily when I am listening to SiriusXM (news channel and music) or an audiobook downloaded through Libby (Greenville, SC, public library) while out walking the dogs and less frequently when on the phone. I have returned to Costco (very helpful, but no solution) several times and have had the HAs returned to Rexton twice. Next trip to Costco is tomorrow (11/13 - prophetic?). I will report to Costco (and Rexton) what I have seen here and will pass along whatever I learn from Costco and Rexton.
