I can't speak for the X2, but I use rechargeable AAs in my Sennheiser EW172 G2, and they work fine. Probably not as well as disposables, but I easily get a full night's show (sometimes two nights) out of my rechargeables.Does *anybody* successfully use rechargeable batteries in their X2? A couple of people said they where buying them and would report back. Nobody has reported back, which does not give me a warm fuzzy about their success.![]()
The X2 needs high voltage batteries, the regular 9V rechargeables will not work.
