Don’t buy if you looking to get the add on to make this the perfect situation for working out from home. Horrible experience If you want max treble withiterally zero bass, these are for you. Comfort: I favor the S600 because the ear loops allow them to sit snug without causing pressure. Even though they were going to pay me $15 for a 5 star review, I can’t do that. I need these for the chargers I have but they either don’t work or break within a month. They look pretty decent, extremely casual. He usually wears this one to church on Sunday. I wear a 9 1/2 shoe, and got the "10" size sandal and they fit like a glove. They dont sell half sizes though, so you may have to just try them and send them back if they hurt.
