If you wear it for a long time, the ear pads may be deformed, so it is recommended to remove the cover and store it after use.
This headphone is positioned in the "EXTRA BASS series", which is known for its rich bass reproduction among SONY's wireless headphones. The allure comes from its specially developed diaphragm driver unit, which delivers deep and tight bass. It also features active noise-canceling, allowing you to enjoy high-quality music even in noisy environments. The incredibly soft ear pads gently envelop the ears, ensuring outstanding comfort. With impeccable all-around craftsmanship, it's a must-have for all bass enthusiasts.
Points to note when fitting the cover:
1. Don't cover too deeply
If you cover too deeply, the tension of the cover becomes strong, making it hard to fit your ears into the ear cups and causing a feeling of pressure when worn.
When fitting the cover to this headphone, it is recommended to ensure that the cover is aligned with the very tip of the housing (right next to the ear pad). (※ Please refer to the attached photo above)
2. Set the cover vertically
This cover has different stretch rates vertically and horizontally, with the vertical direction stretching better.
Since this headphone has vertically elongated ear pads, it is recommended to fit the cover vertically (in the direction that stretches well). To set the cover vertically, align the seam of the rubber band on the cover with the top (or bottom) of the cup. This way, the cover's orientation can be set vertically.
3. Stretch before wearing
After fitting the cover, stretch the fabric by pressing the cover into the inside of the ear pad before putting on the headphones. This eases the tension of the cover, enhancing the wearing comfort. If you feel a sense of pressure on your ears when using the cover, give this a try.

mimimamo Super Stretch Headphone Covers are washable, stretchable fabric covers designed to fit over the original earpads of SONY WH-XB900N headphones. They offer a convenient alternative to replacing worn, peeling or deteriorated earpads. By fitting over the existing pads, the covers help contain flakes and stickiness, reduce direct contact with worn surfaces and keep the earpads cleaner. The soft TENCEL® fabric absorbs moisture and dries quickly, helping reduce discomfort caused by sweat, heat and sticky earpads during long listening sessions. mimimamo staff tested Size L covers on an actual SONY WH-XB900N.
