The receiver is much better than the older version, but the power button on the new version of the XS microphone is awful. It takes me multiple times to get the power to turn on with the flimsy power button, on top of that, I have yet to get it to turn off. Sennheiser should be ashamed of themselves for allowing this to go to market. They could have just updated the receiver like they did and still used the original XS series microphone the way it was. That one was so much easier to turn on and off.
As someone that does a lot of weddings, when I get all my gear set up, the last thing I want to worry about is having problems turning my mic on.
