Keep Your Ears Cool: The Soft Cooling-gel is added under the top layer fabric (breathable Ice Silk fabric) of the earpads, absorbing the sweat in the summer days and keeping your ears cool after a long-lasting use.

Rugged Durability: We added stitching and mighty glue on the inside seams of each earpad to prevent them from splitting. Moreover, our thickened Cooling-gel earpads will never go flat and cause discomfort to your ears as time goes by.

Enhanced Sound: Your old earpads negatively affect the sound quality of your headphones, while our precisely modeled earpads will not affect the sound performance of your headphones and make your headphones look brand-new again.

Flawless Installation: No extra tool is needed and you can complete the entire installation within a few minutes (usually takes 5 minutes). WE CONTINUE TO develop more professional and ergonomic ear pads. Please contact us for replacements or refunds if there is an issue with your purchase.
