I think it's better to leave a review because if you bought a PSP-B1 you might think it won't fit because of the maximum front size. Don't be fooled like me and go to the next size up which is too big. They fit perfectly on the PSP-B1 and have a lot of space. Perfect for my need, namely wintering. If I had one criticism it would be that the velcro straps are way longer than they should be. I can't think of a speaker this size that is deep enough to use its full length. But better too long than too short. You can always cut them.
