I have used this item for a month and I like it very much. It is very sensitive and comfortable to wear. The only problem I am have is one of the ear pieces keeps falling off. I have just sent a email to Allheart to see if they will replace the ear pieces.
I love the sound quality Damn thing piss me OFF the way it hangs around my neck
