Example Input: This product works great with my Sony NEX 5.I was a bit disappointed when the first adapter that was sent to me didn't fit at all. You are supposed to insert batteries through little holes, and as soon as it snaps in place, you're suppose to twist or pull back so the battery will make contact. The holes looked too small for me, but if you force them in with enough force, they snap into place. But now that I've got this one right, it's pretty sturdy.
Example Output: Good Review

Example Input: Not only do this things look great and sound great, the bass is amazing!!! they are very comfortable to wear, but after about 30 days I got a short in them where they connect into your iphone or ipod. Don't waste you money on these
