There is some info about this in the FAQ in post #3, but in general:
- if the hissing happens all the time, it probably means the charger produces too much ripple current, which causes inductors in the mojo battery charger to oscillate and generate the noise - I suspect this is not your issue
- some chargers, especially smart chargers can enter trickle charge mode, when the battery is nearly full, and cause buzzing - I suspect this may be what you are experiencing, so as a first step you could explore using other chargers, or alternatively consider that removing the cable when the noise starts and the battery is say 98% full, is not a serious problem and only reduces your listening time by a few minutes.
I think your correct and today i remove cable. Im charging and listen to music via the computers usb.
Do you have any charger and cabels to recommand? Cheap cable and chargers work as good as expensive?
