You have to wire the plug to eliminate the voltage sent by the sound card. I can't remember if it's the tip or the sleeve, so you'll have to verify with a volt meter. Use a 3 position plug to solder to the mic wires, just don't connect the wires of the mic to the one that has voltage on it

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.

Send it back it is faulty. The battery is shot.

OR

go and buy (2) AAA NiMH rechargeable batteries from here which will be far better quality and have a larger capacity than the ones you have.
