I seem to hear some sort of hissing noise coming from my Galaxy buds, I tried changing the audio codec and resetting the buds but it seems the noise just got louder and now happens when I'm not playing any audio, is there a way to fix this?
Depending on which buds you're using, there are options to hear ambient sounds and enhance them with the wearable app. You may hear a lot of hissing if this is enabled and set to high volume.
