The product works fine but like the other review says I wouldn't put the adapter in a Ipod skin to work out with. The product has difficulty maintaining a connection when it is slid inside. I also noticed that if the connector is on the opposite side of the receiving end of the head phones it can also lose connection. I used it with my computer to talk on Skype and I noticed a break in connection every now and then the batteries were fully charged so that wasn't a problem. It also could of been the net since I was testing them from Kuwait. The wire that connects the headphones is kind of annoying but it's still a upgrade from wired headphones. The headphones themselves put out a good sound, you can even control the volume with the headphones instead of messing with your mp3 player. I have yet to test the mic on the product. I would recommend this product if your just wanting to get rid of the wired headsets. It also works out well if you do not like having a mp3 player attached to your arm while you work out at the gym.
