I purchased two of these. One for my wife and one for myself. She hated hers from day one bacause it wouldn't sync with her Dell E4300. So back that one went. I liked mine, but after wearing it for six hours, came to hate it also.The sound quality is great, but it is too heavy and hurt my ear. Also, at night, the blue LED reflects off our hybrid's window. Very distracting. Too bad. The sound is great but everything else is too big, too heavy and too old fashioned.
