The strap in back is too short. I came to these after trying the JBL 400BT and my biggest complaint was how the sit on top of your ears and compresses them making it very painful to wear for longer than 40 minutes. I will not make that mistake again and will stick with Clarks from now on. what it does mean is that using the volume + and - on my iPhone is far less useful because the increment is too much. But only had the shoe for 2 weeks and they are fallen apart! But, these boiled wool slippers are perfect. ***Before I opened the box, I was expecting the box containing the headphone and accessories to be of good quality, something like what we will see in Monster Turbine products. I am now disappointed. Will say as far as fit. These headphones last me a couple of years and I always re-order the same ones.
