I have wider feet and like my toes to be able to spread out a bit in my shoes and Keen delivers this. Headset adjustment was excellent; metal is used to connect the headband to the cans themselves, not flimsy plastic. I may return the unit. Super cute already comes assembled. I was really excited I found this seller because the price was $4. Save for a bow line from my kayak to the front of the car, it would have been a tragedy. Was able to hookup to my office phone and it worked perfectly. and was sent a random different product entirely that wasnt even a charger. Extremely difficult to install. I will update if anything changes.
