Great for Small Production Teams!
The ME2 kit of the Sennheiser AVX wireless microphone system has made my one-man YouTube production much more efficient. It takes less than 5 minutes to set up, and once you set it up the first time, just turn on the mics and go!
The rotatable XLR connection plugs right into my audio mixer, and the mic clips on my shirt, I'm ready to shoot much quicker than before!
Plus, the audio quality is superb! It's easily on part with my Rode NTG-2 shotgun mic and Procaster desktop mic after post-processing. A level of quality I've never had in a lav mic before.
My only real complaints are that the buttons - primarily the Power/Check button on the receiver and the Power button on the transmitter can be very hard to press without long nails. They're fairly mushy and unresponsive.
The battery on the receiver is also much lower-capacity than the transmitter, so it needs charged more often, BUT this is somewhat made up for by the receiver also being Micro USB chargeable, thus meaning you can plug it in to stay charging very easily.
The wireless range is great, battery LEDs and battery indication on the LCD screen of the receiver are useful, and it always stays in-sync.
