The Striva looks like a nice Headset. $450 bucks each though... WOW. advantage is you can stream internet radio (Free) to the set (with set-up and software from a computer). Although you have to be in a Hot-Spot. A guy can buy an i-Touch and a nice set of aviator Cans for half that price and do the same thing. But it is a nice high tech idea.
I like Koss myself. It was the first set of cans I owned some 35 years ago. Milwaukee based and family run and majority owned.
Still think SKUL has it's following... Great ear-buds and cans for the dollar. I own a LOT of pairs! :)
