Recently replaced the earpiece covers. They still sound amazing. I recently upgraded to the QC Ultras. I am including the headband cover kit because the pleather is worn on the headband. I did not like the look of the kit. Only the earpieces. I brushed off the pleather to make them look smoother. Please see pics.
Here is the link to the manufacturers website.
