Does the job, but doesn't fit or look quite like the original. I spent an hour trying to get the end caps to hold the headband down and gave up. This was certainly cheaper than a new pair of headphones. I travel a lot and my Bose headphones are awesome, but having bits of black on my sucked. These fixed the problem, just not as elegantly as I had hoped. I think a good comparison is the ear pieces which look exactly like the original.
