Super tight and stiff. Altho it takes me a minute to get them out of its charging box (because if my my nails) theyre the most conformable to wear ALL day long, which, by the way, is as long as they stay charged! See image for how different the heel is. I love the two-way zippers on the larger pocket so I can secure the battery pack but leave room for the mic cord so it doesn?t kink. Sound is clear and wonderful. To date Ive used the large squeeze weight retaining clamps, but when I squat enough weight to bend the bar those squeeze clamps gradually slide out. I know this case will protect my Airpods from scratches and scuffs, and because I attach them to my keys I likely won?t drop them again. Then, fortunately, I discovered foam ear-tips. The case is very durable and protects the case well. This is really easy to assemble and looks really nice.
