This earmuff is from '3M', a company that produces various daily necessities. Despite its relatively affordable price, it is lightweight, has sufficient adjustment mechanisms, and offers excellent noise isolation. It's highly popular and can be considered a staple model.
Points when fitting the cover:
1. Don't fit it too deep
If you fit it too deep, the cover's tension increases, making it difficult for the ears to fit into the earmuff, leading to a sensation of pressure when worn. It's recommended to cover only the ear pads when fitting this earmuff. (Please refer to the photo above.)
2. Position the cover vertically
This cover has a difference in stretchability between vertical and horizontal directions, with the vertical being more stretchable. As this earmuff has vertically elongated ear pads, it's advised to align and fit the cover in the vertical direction (where it stretches well) for a better fit. When positioning the cover vertically, ensure the seam of the cover's rubber band aligns with the top (or bottom) of the cup. This way, you can orient the cover vertically.

mimimamo Super Stretch Headphone Covers are washable, stretchable fabric covers designed to fit over the original earpads of 3M PELTOR X4A 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 3M PELTOR X4A. This model was added to the mimimamo compatibility list on August 23, 2018. The compatibility information, fitting photos and installation video on this page are based on a physical fit test.
