A practical strap
More practical than the original strap. It's strong and less messy. The fact that the original strap is made of fabric is not at all hygienic. A quick wipe with alcohol and you're done! The battery is a plus! It's a shame, though, that you can't connect it to your PC via USB. You have to disconnect the battery to use the input on the headset and not the one on the back. After that, you can certainly use the airlink, but when you want to transfer files to the headphones, it's less practical. It's a minor detail, but hey... All in all, I'm very happy with it!
