I bought these pads to replace my age old originals. They are very expensive items but eventually over a couple of years usage, they will show their age. Sadly, Thomann sent me the K701 pads which aren't the correct colour. They are a silver grey whereas K702 are a dark pad. I just coudnt bear to send back to Germany and wait for the turnaround as my deadlines are tight. Im sure had i asked, Thomann would have sent me a complimentary set to cover the inconvenience caused. I didnt go through the long winded customer support process, so we shall never know.
They are very easy to fit. They will make the product feel like new. Be aware that over time, the cups create a shape to your ear, so a new set might take a little time to make this shape and subsequently mixes may seem slightly "off" compared to when you had them at there sweet spot
