I replaced my sleepbuds because of the problem, though the interference noise I got is pretty low volume, they sent me an second pair, I just got it yesterday. The new pair is way worse, it is absolutly unusable. It would do a mid volume high frequency whine every couple seconds, gives you a big headache. I am on the hotline waitling 20 minutes + for a return and refund now. When they said they found a solution and are sending out new batch, they are lying through their teeth. You should call it whining sleepbud that interrupts your sleep.
