The wireless headset works. And they offer tech support and warranty so seems awesome deal. The set comes with multiple skins so you can get the best fit for your ear when youre working out or just listening at home. Being a trike, that meant I needed 2 of them for my front tires. A product that actually feels like it looks as advertised! Regardless, they are cute in a funky way -- Drew Barrymore as Crocs new brand ambassador helped me get over the stigma of wearing Crocs enough to give these a chance. The plastic part on the top broke upon assembly and the metal is very thin so one piece bent during assembly as well. Im now able to lie down partially on my side. These were a great buy. Cant say Ive used these for making phone calls so cant comment on the microphone and sound quality when using it for phone call purposes.
