I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.

Ex Output:
Negative


Ex Input:
This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.

Ex Output:
Negative
