What I've just noticed with mine, the annoying sound in left cup last only for first 30 seconds from turning them on, after that time you can easily decrease volume to non and you can barely hear ticking or white noise, (which then is hearable only in very quiet places, other way almost impossible to detect). So i guess this is the way how they works, BT probably need some time to estabilish connection and then they become much quieter. Therefore during the listening music, even with extremly low volume there is nothing that you can hear instead of music.
Please you also note that if you press pouse then H7's probably turn off after few seconds due to battery saving purposes, and that way after push play again they will need to estabilish BT connection again for next 30 seconds, which may bring you to the wrong conclusion that this ticking sound is there for whol the time.
Hope that mine thoughts claryfied that for you.
