WE CONTINUE TO develop more professional and ergonomic headphones earpads. Please contact us at any time if there is an issue with your purchase. ENHANCED SOUND: Your old earpads negatively affect the sound quality of your headphones, while our well-crafted earpads will seal around your ears brilliantly, ensuring you excellent noise isolation and enhanced bass. RUGGED DURABILITY: Adopting the High-density foam and the softer protein leather, our earpads will never go flat and cause discomfort as time goes by. Also, we added stitching and mighty glue on the inside seams of each earpad to prevent them from splitting. FLAWLESS INSTALLATION: Besides the earpads, a pair of scrims, and a user guide, you will get a plastic stick, making the entire installation easy and fast (Usually 5 mins). COMPATIBLE WITH: QuietComfort 45 (QC45)/QuietComfort SE (QC SE)/New QuietComfort Wireless Over-ear Headphones. Please confirm your headset model before purchase.
