This headphone is positioned as a mid-range model in SONY's wireless headphone lineup, but it is equipped with a high-performance active noise canceling feature inherited from the company's flagship "1000X series". With just 1 hour of charging, it achieves a long life of 50 hours (when ANC is off), and its extremely lightweight and low earpad pressure make it comfortable to wear.
Key points when attaching the cover:
1. Insert the rubber band of the cover into the gap
It is recommended to insert the rubber band part of the cover into the groove between the earpad and the housing. (Please refer to the above attachment photo.)
At that time, there is a seam in the rubber band of the cover, and that part is thick and difficult to insert. After inserting the other parts, push the seam part in last.
2. Orient the cover vertically
This cover has different stretch rates vertically and horizontally, with the vertical direction being more stretchy. As this headphone has vertically long earpads, aligning the cover in the vertical (stretchy) direction will make it more comfortable to wear. To set the cover in a vertical direction, attach it so that the seam part of the rubber band is at the top (or bottom) of the cup. This way, you can set the cover's orientation vertically.

mimimamo Super Stretch Headphone Covers are washable, stretchable fabric covers designed to fit over the original earpads of SONY WH-CH720N 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-CH720N.
