As the title suggests, these replacement rubber sets fit perfectly and last for years. In fact in my experience, they last longer than the originals. I bought these in 2015. I'm buying a few replacement sets now, 11 years later. For context, I wear this pair of Mars every day, and apart from the ear sleeves, everything is still perfect. Even the ear sleeves outlasted the originals by years, but eventually, anything will need to be replaced. Moreso on a pair of almost indestructible frames. If you have a pair of XMetals, buy these.

An excellent product for an excellent product. 5 Stars
