Theyre solid, lightweight, super easy to install, and they look great. The reason why they do this is to save material costs. they are either in your ears or around your neck or in your bag or around the rearview mirror. Not sure if I will use it for that. The headset works great for that purpose! They were not a good fit for my feet, although a very nice Sandal I dont have to worry about being out of town and having a dead battery become a problem. The set up was also surprisingly easy too. IF I HAD BEEN TOLD THAT THE PRODUCT WAS USED, I WOULD HAVE NEVER BOUGHT THEM. Blister on top of my foot 1st time wearing.
