So far, the pads that fit the K545 are HM5, Shure SRH750, & Sennheiser HD280. I have the HM5 Valor version. while the pad is comfortable I felt the bass has deteriorated. I'm not sure if the leather Thick version is an improvement. Out of all the replaceable Pads, Which one has the best sound quality to the Original / Stock Pads or Better than the Originals. Thanks.
HD280.
If you find them uncomfortable, HM5 pads are the next best thing, but the pleather version. Much better than the originals.
