Don't know squat about what's good in headphones. If you got $150 to buy phones for playing guitar mainly what would you be buying? Should I buy studio isolation monitor style or a open air over ear design? Looking at these Telefunken cans as a possibility for studio musicians they sell but don't know how good they are Option 1 http://store.t-funk.com/p/thp-29-isolation-headphones?pp=24 Option 2? Way more money http://store.t-funk.com/p/wiking-headphones?pp=24 Also are wireless headphones inferior to old fashioned style with a cable regarding sound quality?
