annoying hum/buzz after a few hours
My Sleepbuds seem to have developed a new problem. Unfortunately this one seems like dealbreaker. I'm not really expecting an answer here, but posting in hopes of hearing from someone else having the same problem.
Everything is fine when I first turn them on and go to sleep. Hours later, if I wake up during the night, there's a noticeable hum/buzz sound in addtion to the selected Bose track. I'd call it a hum, although it has a definite pitch. It isn't loud, but it's enough to be annoying and there doesn't seem to be any way to get rid of it. Resetting the buds (using the charging case), or restarting the app. Increasing the volume also increase the hum, rather than masking it. The tone is present on all sounds but some are better at masking it than others. However, the sounds that work for me - Cascade and Warm Static - don't mask the hum. The problem seems to get worse over time; by early morning it's so loud that I have to give up and remove the buds.
The next day, I verify that the hum is still there, then put them in the charger. After a few hours of charging I try them again and the hum is gone.
I'm a bit puzzled about why I didn't notice this for the first month of using the Sleepbuds; maybe it wasn't there. I considered RF interference as the source, but moving around the house or shutting off the phone makes no difference. At this point I'm out of ideas and can't use the Sleepbuds because I know I'll have to remove them sometime during the night. I plan to stop at the local Bose store and see if they have any ideas.
