Most people just use adidas style flat bottom slides for inside. Coupled with my Amazon Music I listen for hours skipping songs without having to touch my devices. I understand most people with sennheisers can afford this but it doesnt leave an excuse to me that my audio technica m50x cable lasts longer for a cheaper pair of headphones. The bonus is that they are also large sizes, so you can fit multiple items in one bag. I am one of "those people". Also the way the lighting changes when pressing the fn key is distracting and annoying. but is especially uncomfortable when you drop them down to let around your neck for a break. At first, I was concerned about the fit. Surprisingly works soooo well! The battery and buttons work very good.
