As has been mentioned in some other reviews, the fit of the replacement pads is not perfect. Because of the slightly wrong size there is a small amount that doesn’t tuck in. That being said, the pads are still secure and it can’t really be seen easily. It’s not ideal but isn’t a deal breaker for me. I find the comfort of the pads to be reasonable but not as good as the originals. If you are happy to pay around $40 for the original Bose product, that’s probably the way you should go. If you don’t want to pay that much and are willing to slightly compromise the fit/comfort, give these a try. Just don’t expect the quality of an original for less than half the price.
