New Jawbone not the best

Splurged on the new Jawbone bluetooth earpiece. Would much rather have the old one. The old one, once I'd won the struggle to get it on my ear, stuck there perfectly. The metal earpieces could be bent for a perfect fit. The new one is easier to put on but I can never find a fit that works. And the new one has such a sensitive on-off switch that I can't leave it anywhere--shirt pocket, briefcase--without it accidently getting turned on. I've taken to carrying it in a little hard sided case that came with a laptop webcam. Sound quality? Seems to be better but for the first few days I kept disconnecting calls as I tried to get the thing to fit correctly onto my ear so I could hear.
