Let me start off by saying that I absolutely LOVE these Coosh Bluetooth 4.0 Extended Range Headphones. These headphones have Bluetooth 4.0 wireless technology with a 30 foot range. It has padded headband and pressure relieving ear cushions. The headband is adjustable and the ear cups swivel. The Coosh Bluetooth 4.0 Extended Range Headphones has a 450-mAh rechargeable battery for up to 15 hours of operating time!!! It also has a battery level indicator for iPhone and iPads. On board volume, music track, play, pause, and power controls puts everything at the tips of your ears for easy access. Coosh Bluetooth 4.0 Extended Range Headphones also has a built in microphone for hands free calling and a line in auxiliary port for conventional headphone use, and the cord is supplied! It comes in a little hand carrying case to store all of it in! I have personally used this product with Pandora and made a phone call to a relative. The mic actually works really well. The other person could really hear me perfectly clear. When I was playing music, I could hear the music perfectly without anyone else in the room being able to hear what i was listening to. The ear cups are so comfortable as well. Not like other headphones that say they are comfortable and not, these headphones really were. I had them on for probably about an hour and when I took them off, my ears didnt hurt like with other headphones that claim to be comfortable. I would definitely give this product a 5 star!!!
