I think these are great and like that they are 1/3 the cost of the overpriced Bose replacement ear pads. They went on easily and seem to be of as good quality as the original ones. When I sat these side by side with my old, original Bose ear pads they were slightly thinner and firmer then the old originals but this made no difference in fit or performance for me. In fact, these new ones felt better. Following installation of these pads I pulled and tugged on them within reason and they seemed durable and not prone to tearing and breaking. Also last week I wore them on a trip through two three hour flights, loud airports, long drives, etc. They felt fine and sealed out noise perfectly and didn't show any signs of wear or damage. The reason I mention in this review my perceived durability of these ear pads is I read some reviews where people said they tore during or after installation, had trouble getting the double sided tape off, etc. which concerned me. But after taking a chance and trying these ear pads for myself I see no issues at all. I suspect the people saying these things just weren't able to install them correctly which in itself is surprising as installation is as about as simple as falling off a log.
