Input:
I have purchased a pair for me and used them a number of times. After bragging to my wife about how good they worked she had to try them now we own two pair. We really enjoy using this product they work very well. I also purchased a pair for my brother-in-law he tried mine and liked them so he got a pair for X-mas. The best thing about them you don't have to take them off to talk to somebody and you can actually hear better with them on then off. If you purchase these I have no doubt you will be satisfied.
