Ex Input:
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.

Ex Output:
Good Review

These were ordered for our sons wedding after finding the exact same product in local stores and not at a price we could afford. Good buy.

Good Review

We had trouble with the product. When we put batteries in, they did not power up at first or turn on. Once turned on, all that came out was static.

Ex Output:

Bad review
