I was really impressed at the comfort of the straps. Button locations located logically. Its not bad but its not something that I am crazy about either. The OEM Apple 20W Charger is definitely up-to-par in terms of quality and power delivery speed, but it is too expensive. I am using them along with the TMS® 2 Pairs J-Bar Rack HD Kayak Carrier. Audio Technica claims to have used a soft outer padding, with a harder inner padding. The noise cancellation must be a new generation type because it is awesome. It will get matted down and fit better after a couple weeks. It fit my crankshaft and seemed to work fine. It was comfortable, with good sole padding, a firmly gripping rubber sole, was easy to put on and they stayed on.
