About this item Compatibility: Fit perfectly on WH-XB910N EXTRA BASS Wireless Bluetooth Noise Cancelling Headphones. Please confirm your headsets model before purchase. ENHANCED SOUND: By adding high-density memory foam, our earpads will comfortably conform to your ear without affecting your headphones' sound performance or noise cancellation. RUGGED DURABILITY: We added stitching and strong adhesive on the inside seams of each earpad to prevent them from splitting. Our thickened earpads will never go flat and will provide continuous comfort over time. FLAWLESS INSTALLATION: Besides the earpads, you will receive a detailed user guide, making the entire installation fast and pain-free (usually around 5 mins). Dimensions: 7.68 x 5.2 x 1.06 inches.
