About this item COMPATIBLE WITH: Studio 1.0 (1st Gen) Over-Ear Headphones. (DO NOT FIT Studio 2 and Studio 3), please CHECK your Headphones' model before purchase. FLAWLESS INSTALLATION: Besides the earpads, you will get a plastic tool and a user guide, making the entire installation easy and fast (usually 3 mins). Rugged Durability: Our earpads are made with high-density noise isolation foam and softer protein leather, while stitching and strong adhesive are added on the inside seams of each earpad to prevent them from splitting. 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. Dimensions: 7.87 x 5.24 x 1.02 inches.
