bluetooth wireless headphones in ear waterproof with built in mic

I connected these easily to my mobile phone and the sound is amazing when listening to songs on youtube.They can be used for iphone and android mobile phones.They are wireless but have a cable attached from one earpiece to the other which helps in not losing one or the other earpieces.When I made a phone and received phone calls the sound was crystal clear and the other person could hear me clearly too.They are rechargeable and comes with usb cable to charge it.The battery lasts up to 8 hours talktime and 250 hours standby which is really good.I would highly recommend these and is good value for money.
