[EX Q]: This is the worst money i've ever spend on my kindle fire it's so slow u can't do anything at all I couldn't even download this game if I wanted to pay for it.
[EX A]: Bad review

[EX Q]: I bought a pair of these at first and one has stopped working just after the return day. They sound great while they work but if you want headphones that will last you buy something else. Also tried to get in touch with customer service twice for this issue, only got an answering machine most times. Not worth trying since they were never able to send me another headset to make it right. I'm done returning them. Amazon took care of them quickly so I give them five stars.
[EX A]: Bad review

[EX Q]: great product. It is very convenient the ease with which you can put in your work and take it out again. No need to leave on there long periods of time,just place a couple pieces on, close them up, then move on. Saves time too. Also purchased another one at Christmas for mom who really appreciates a simple, well made item. Thanks, Amazon. I had searched many places only seeing inferior items that fall apart. Not this time, this item was perfect! The seller delivered fast. My thanks to them.
