I love the freedom of listening to a playback while grabbing a drink, snack or what have you without actually being in the same room. There are many times having a large headphone can start to feel heavy when listening for prolong periods. I've also picked up a lavalier mic which I can connect to the M2R for "ambient" pickup of external sources like when someone's talking to you and can still have the ear buds on. Great product! Have not needed any tech support since day one. Manual is cut and dry and user friendly. Bought another bodypack for a second user. Great price point overall especially for a soloist or duo. Cons? the included ear buds are ok...but it's a matter of personal choice I think. Just gotta try what tickles your ear methinks! BTW..did I mention STEREO?
