ExpressTrain Did you happen to find a permanent fix? I have the exact same issue with my Ear (2024), there’s a high pitched quiet noise that’s only coming from the left earbud, tried resetting them, nothing worked, though I noticed after I toggle the personal sound profile on or off, the noise would stop but it would come back after 5 seconds, so before I send them back, I want to know if it’s a software issue rather than a hardware defect.
