I bought the Cardo Scala 700 initially for my 16 yr old son. It was so good out of the box that I have bought a second one now for myself. Its great for driving down the road and it pairs well with a Sanyo Katana DLX and a Sanyo M1.It does well until the surrounding environment becomes extremely noisy or windy. But in all other common environments its great. People when asked, say it sounds as good or better on their end, as my cellphone itself does; and I can hear others just as well. Response to all voice commands is great! I can check and navigate through my voicemail without a hitch.I have very carefully researched headsets for a few weeks before deciding on this purchase and I strongly recommend it - if you want something on the budget end. If you want something that is truly creme de la creme and willing to pay for it; then you need to get the Aliph Jawbone. These are the only two headsets to get on the market at the moment.
