Inside there is a net-like pocket to store cables helmet and some medium sized accessories. A small hook is also provided.
It accepts in-ear models, on-ear and those of moderate size such as helmets Creative Tactic 3D Gaming Fury and Philips SHB7000 / 10 Bluetooth. By cons it will not tolerate the towering helmets or with large headphones like Peltor 3M Optime III (hearing protection), the Logitech G930 Gaming or the Sennheiser HD 650 (high gigantic speakers).
I recommend this case but it will be imperative that you check the size of your helmet. It can also be used as a travel kit or to store its various accessories (cables, memory cards, sunglasses, chargers, keys, etc.). Moreover it is guaranteed for 2 years.
