I hear good things about Sennheisers but not used them myself.
I've just come back from the Apple store in town. Tried out all the headphones.
Very impressed by the Bose quiet comfort, i think perhaps justifies the 350$ price tag.
The dr dre beats, both versions of the head set i dont think are worth it. They sound good and look good but nothing in particular to justify the steep price tag.
I was very impressed by the Skull Candy Aviator series. First skullcandy headphones i actually think are good. http://eu.skullcandy.com/aviator/
they also look cool like steampunk style. However they are even more expensive than the Bose Around Ear.
Overall best value is the Sony i linked before and the Grados. Under 90$ typically.
