RUGGED DURABILITY: We added stitching and mighty glue on the inside seams of each earpad to prevent them from splitting. 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. FLAWLESS INSTALLATION: Our earpads perfectly fit your headset base. No extra tool is needed and you can complete the entire installation within a few minutes. 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. 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 time of use. COMPATIBLE WITH: Our ear pads fit many brands of headphones, such as M50X, M40X, M30X, Cloud 1/2/Core/Mix/Alpha, Arctis 7, Arctis 7P, Arctis 9, Arctis 9x, Arctis Pro, Arctis Prime wireless, MDR-7506, MDR V6, Stealth 500, Stealth 600, Stealth 700 and so on. We show all the compatible models in the list for your reference.
