Needed to replace my Beat Solo 3 cushions, Wicked Cushions came highly rated - simple to replace and very comfortable, can't speak to long term use but are quality.
Nicely included was a generic code for 20% off next order, across their whole range.
A solid range of replacement headphone cushions across most brands.
Enjoy.
Good muffs. Got replacement ones that have extended my hesh2 a few months ago and going strong.
