I was looking for some open backed cans and heard decent things about these Philips units and decided to give them a try. Leider ist mir das Riemchen über den Zehen zu schmal. Set up was super easy. Mule style has a small lip on the back that helps keep them securely on your feet. 5 for my daughter that wears 5. I also like the fact that it doesnt have a lit up indicator if its on or off on the switch itself because I think that would be an annoying feature to have in a dark room right next to our bed. They dont pinch the toes and the soles are solid so you dont feel like youre going to topple over when you walk or stand. I was able to get maybe 8 pair in. This is everything I needed! Ive lost the ear piece on other headsets because they snagged on things as I lived my life.
