WE CONTINUE TO develop more professional and ergonomic earpads. Please contact us for replacements or refunds if there is an issue with your purchase. TIME TO CHANGE YOUR OLD ONES:Why not buy a new dress for your 300$ Headphones? Don't be afraid to take off your old earpads and put on our new ones!. OUR INGENUITY: Adopting the High-density foam and the High-grade protein leather, our earpads will seal around your ears brilliantly, ensuring you excellent noise isolation and enhanced bass. 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: QC2/ QC15/ QC25/ QC35 I/ QC35 II/ Ae2 / Ae2i / Ae2w/ SoundTrue Around-Ear/ SoundTrue Around-Ear II/ SoundLink Around-Ear/ SoundLink Around-Ear II Headphones.
