OK, so I ended up acquiring a used Sennheiser digital 1000 wireless unit last week, and it is amazing. My wife was upset when I got it.....not because I spent the money, but because she bought me a Shure ULXS14 for x-mas! So she gave it to me early so I could play around with both of them. I cannot find faults in either unit. They both sound great, get good battery life, and are constructed wonderfully. My issue now is which one do I keep? Although there was almost a $300 difference between the two, that is really not a factor for me. I just want to keep the better unit. And my wife honestly does not care if the Shure stays or goes. So I would appreciate any cons you guys and gals could offer on either unit to steer me to a winner. I've read the various threads, and the major con I have found is the lack of battery life people have reported with the Sennheiser, but I have not found this since I was able to achieve 4-5 hours on a single 9volt. HELP!
