These don?t seem like Keens. Great clamping system. Weird size for the pics so haven?t put pics in it but plan to. Now with the new cord on the HD600 I like them much more than before. I wore them for less than a week and the stitching along the soles came undone. ??????????????????????????????????????????????????????????????Bose???????????????????????????????????????????????????????????????????????????????????????????????????????????? The sole of these is great -- I can go to the mailroom in them and not feel like I am walking outside in slippers. 1) The automatic volume control makes this headset useless. Great utility value for the price. Very useful when you?re out and about shopping yet need to take a call or want to listen to music but still be able to hear people around you.
