WE CONTINUE TO develop more professional and ergonomic earpads. Please contact us at any time if there is an issue with your purchase. FLAWLESS INSTALLATION: Besides the Earpads, you will get a plastic stick, making the entire installation easy and fast (usually 3 mins). OUR INGENUITY: Adopting the High-density memory foam and the High-grade protein leather, our earpads will seal around your ears brilliantly, ensuring you excellent noise isolation and enhanced bass. COMPATIBLE WITH: WH-H900N (h.Ear on 2 Wireless) & MDR 100ABN (MDR100 h.Ear on Wireless) Noise Canceling Over-ear Headphones only. 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.
