From the tester:

This headphone model has been continuously sold by SONY as a studio monitor headphone for many years. It has been adopted by a significant number of recording studios in Japan and boasts a market share that makes it practically the standard in Japanese recording studios. Despite its rugged appearance that suggests it's designed for professional use, it is more durable than consumer models, and the availability of spare parts for repair is also a plus.

Key points when fitting the cover:

1. Fit it snugly
It is recommended to cover not only the ear pads but also the housing completely. (Please refer to the photo above.)

2. Orient the cover vertically
This cover has different elasticity in its vertical and horizontal directions, with the vertical being more stretchable. Given that this headphone has vertically elongated ear pads, it is better to align the cover vertically for a better fit. When fitting the cover vertically, position the seam of the cover's rubber band at the top (or bottom) of the cup.
