Review title: Not what was expected
Product review: I purchased this unit based on owning a prior Sennheiser headset. This unit is nothing like the old one. It is quite a bit flimsier, less comfortable, not loud enough, and the noise cancelling unit is large and unwieldy. In addition, the power button is easy to turn on by accident and thereby drain the battery. I will be returning it when I return from my trip.
