These are just about adequate as a replacement for the original Bose ear pads. They fit fine on the headphones, but are substantially less padded than the Bose version. Whilst this gives them a slimmer profile that some may prefer, they are far less comfortable when worn for extended periods such as long-haul flights. I use my headphones for about 2 hours per day for the commute to/from work, and for regular long distance travel, so these are not really right for my needs. I will be ordering genuine replacements from a Bose dealer.
