PROBLEM: Bought from AMAZON for my mother and they work great. They sound clean no noise when playing CD's.

SOLUTION: Good Review

PROBLEM: This is my second MDR-V6's I've owned. The first lasted 6 years before the plastic cracked on one side. But I kept them outside in all weather so they didn't seem to matter too much either. So when I picked up this new pair, I just knew that if anything would do it, these would. They're very solidly built, and not at all flimsy like some of Sony's...perhaps there were a few bad ones, but mine came looking perfect unlike another person's review.

SOLUTION: Good Review

PROBLEM: I got this book to give my cats some variety and excitement in their play times. They are NOT interested in these games, nor do they like them at all. It was a waste of money.

SOLUTION:
Bad review
