Buy these up. I promise you, working for the number 3 cell phone provider (based on subscribers), I have found many less than satisfactory headsets. Unfortunately, I've had to tell many customers that their $100 headsets were just plain bad. I love the scala-700. In fact, I've bought an additional one for my mom for her new phone I've bought her, and she soon will love it too. Cardo Systems, knows bluetooth, and I have yet to have imcompatibility issues with a bluetooth phone. More is not always better (in this case anyways). You wont be disapointed. I've recommended this headset to many customers, and many have thanked me personally. I wish more people would look to save themselves some money and also not sacrifice quality. I keep my phone on at nights now, with my headset close to bed, all i do is put it on and press the button to take the call. 10 hours of talk time is amazing, no phone even has those stats. If you're not loving this headset, no headset will satisfy you. Even the packaging states "The Bluetooth Headset for Perfectionists".
