Query: It's up, it's down, it's up, it's down...

Too bad there isn't a little blue pill for this head piece! Great sound quality - the best I've had in a bluetooth - but the design is awful! It just doesn't stay in position! First it's up in it's correct position, then it's flopping down. VERY disappointed. It went back to after the first couple of days. Also, the charger design is pretty iffy. Oh well. Save your money, don't buy this one.
