I have tried many different bluetooth devices and this one is the worst. I had to hold my phone (Ipnone) so close to it I may as well have put my phone to my ear. When my phone was clipped to my belt the BT500 you cut in and out when I was either listening or speaking. While wear the BT500 it was like walking around with your finger in your ear. There are other bluethooth devices that rest on your ear instead of in your ear. I would not reccommend this product.
