Quality is super smooth. I wear US 37. rt45h5809sl I havent compared these to the other pairs so i have no idea if these are actually better. I will say that these completely satisfy the reason for which I bought them. rt45h5809sl 5 says 9 7/8 inches and 25 centimeters and is not, is one more number. rt45h5809sl I was surprised at how few options there were for really good speaker/high quality stands for my AudioEngine A5+ powered speakers. They have a very thick inner sole in them (Im guessing memory foam) that is pretty soft, but not mushy like some memory foam is. My only complaints are that the 5/8" hitch pin bolt provided to "lock" the rack into the hitch receiver is difficult to secure with the wrenches provided, and that these wrenches do not fit the 17mm nuts on the provided hitch stabilizer. rt45h5809sl Two ear pieces are comfortably fitted with my ears by slight adjustment of headband. I would concur with the description that if you wear a half size to go down (as in buy 10 if you wear 10-1/2 ).
