I am a very loyal Motorola customer. All of my cell phones have been Motorola. So, naturally, I bought a Motorola headset when I decided to get a Bluetooth headset.There were several things I didn't like about this headset. First, it changed the ring on my PEBL to the annoying ring you get when you plug the phone in for charging. I had the phone on vibrate but when I bonded with the headset it made the phone ring and not vibrate.The other thing I really disliked was how it felt on my ear. It always felt like it was about to fall off at any momment. The loop on it never made it feel secure.I punted this headset in favor of the Plantronics 665 and am much happier with that headset.
