From the brand
COMFORTABLE & DURABLE: The replacement ear pads are made of high-quality foam sponge upgraded stitching to prevent them from splitting.
ENHANCED SOUND: Memory foam enhances noise blocking to provide a perfect audio experience.
EASY INSTALLATION: Pull out the old earpads. Slip and tuck the edges of the new earpad into the headphone groove. Stretch if necessary.
ULTIMATE COMFORT: Smooth surfaces will not flatten overtime or cause discomfort. Feels better than your original earpads for the JBL Infinity Glide 500 headphone.
