Definition: Given an Amazon customer review, write a title for the review. The preferred titles are under fifteen words.
Input: A friend had one of these he used with his mobile phone in public places such as restaurants and airports.  This one is obviously a less quality model.  When talking on the phone the folks on the other end of the line complain of the poor sound quality and an echo effect.  I tried it out from their perspective using a friends mobile phone.  The sound quality is terrible.

Not what I expected
