Sennheiser MM100 bluetooth not working
Yes I had the same problem.
Under some circumstances the MM100 freezes (didn't figure out when just yet).
It's a software issue inside.
Solution: open left speaker (the side with the charge connector and hence the battery).
Discharge the battery (or just short circuit for half a second) and it works again.
Sennheiser should built a reset button on these things.
Sound fades out on both earphones
The chance of both speakers going bad at same time is remote. Your ipod is at fault and has something wrong with its output circuits. Check to make sure that there is no muting circuit inadvertently turned on.
