I just got the iPhone 4 and I am in the market for a new set of headphones. I'd like good sound quality and iPhone controls. I'm also leaning towards the flat cable (tangle free) types. Three that I'm looking at: 1) Jays A-Jays Four 2) Ultimate Ears 500vi 3) Diddy Beats by Dr. Dre/Monster (This one I'm actually only adding to the list for the style as I really dont think I'll be giving Monster/Dr. Dre or Diddy my money) Any thoughts/suggestions? Thanks!
