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:
Standard Michael Bay garbage. Totally removed from the original idea, especially concerning Optimus Prime's character. The ideals the character originally stood for are completely ignored in favor of kill shots and 'Murican tough guy crap.

Ex Output:
Negative


Ex Input:
They are at a party playing mostly acoustic guitars and bongo drums. They sing some Beatles tunes as well as their own. They have allot of fun on this and it's an unusual album.It says instrumental but they do sing and they sing acapella's too that's where the other tracks are. There are 2 different albums and one does have 20+ tracks

Ex Output:

Positive
