I first went by peoples reviews and ordered a 1/2 size smaller and when I got them they were a 1/2 size too small. Fits great, high quality. The only volume control would be on the headphone end. I really like them although the come a bit small since my foot is a bit chunky. I admit to being hard on them, also. The case feels sturdy enough for our needs and would be nice and portable for taking away on holiday for example in hand luggage etc. I finally found a hack when I googled it. Still, I love the feel of these and will continue to use them until a similar but better option comes along.
