I just got the headset for two weeks:Pro:- it's comfortable.Con:- i got complaints that it sounded echoey and in very low volume during the first 5~8 seconds in the calls.- it's not user friendly to adjust the right volume/sound setting.When I was about the call customer support and ready to return the product, I saw an earlier Amazon user review and followed the posted sound setting. It's working much better although it's not really up to my expectation for a $190 product. I'm keeping it for now if there isn't any further cos i'm just too lazy to do return/exchange.
