558 a little bit uncomfortable than ad700. but it FIT my head. and still very comfortable. while ad700 - in my opinion - king of comfor. my head is smaller than average. so it a bit loose. if you have a bit large head. ad700 will fit your head . like many comment i've read on Youtube - " fell like i'm wearing nothing"
