I have tried the DC x11 they're pretty nice for a 'cheaper' (than bose) headset. they don't really provide a lot of pressing force against your head, so i didn't think that they sealed very well. I've got the bose now and they're an amazing headset. I wouldn't want to wear anything else. I've tried the Telex and they were big and bulky. Next to the Bose I would got with the x11 just because of the size for sure though.
