Iphone Bluetooth headset not working well

the conection with the Iphone fails just after the connection. It doesn't maintain. It looks like the connection is weak. I bought the Iphone bluetooth headset to maintain the brand and to take advantage from the system. It fail. It doesn't work. Please help.

Hi Ronald, as the iPhone is new technology and therefore still under warranty, given that you have tried a normal headset and a bluetooth one without success, I would contact Apple and send it back under the warranty for them to look at.

Thanks for tyou input
