I found Wicked Cushions when I researched replacing the ear pads my self. I read such great reviews of this product, which is why I bought it. I just wish there was a way to have something this good without having metal digging into my back. This model was convenient with the freedom that come with the battery (so is the 300) but the 300 was more power full and it seem to have better sound . They are way better than my old Turtle Beach headset. This is despite the fact that the cable is detachable and is unique to this model - you cant use anything generic, it has to be Sennheisers own, and it has to be for the 2. I would be aghast it this sole is leather. 5 or 12. But I dont like too much the pac as they have the tendency to stick together and when I only need one I may end up using three because they are stock together and if I try to separate them will break making a mess. 5 regular depending on the shoe so i bought a 10 to 11 slipper oppsed to the 8 to 9.
