Theyre extremely comfortable, easy to slip on to the AirPods themselves, highly recommend! I ordered a size 9 and they fit fine but they are a bit loose. As for design, I think it could be improved if it had a lid that locks or clicks into place with some plastic to ensure the Jabras lid doesn?t open and that your earbuds fall out. These babies deliver on that front. I actually bought these in silver and ivory- my review is about the ivory pair I received. Theres actually very little difference across this parameter. You can get these from Astro directly for $9. Yes, they are more costly then a $20 pair but as the saying goes-You get what you pay for! This backpack takes the stress off my shoulder (or wrist if carried) and puts it on my back where it is no problem. If already have a mixer; THEN, EVEN BETTER.
