The product seems to be of good quality (although the ear cups are a little smaller than the original). My issue is that the instructions state the original foam filter isn't attached with any glue or tape, which isn't true - my originals are glued in place. Other users have reported permanent damage after ripping out the original filters. Seeing that I bought the headphones for their large earcups and this product for the replacement filters, it's useless to me. Could be a good buy if you need new pads and don't mind a tighter fit.
