I finally realized after listening to so many different headphones, $100 pairs to $5000 i still realized that, i still love my sennheiser hd650s. i have never heard another headphone that can produce detailed but heavy bass like the sennheiser hd650s. Even though the sound is a little laid back, i still love them. i tried the grado sr325is and i just didnt like the sound, it was sort of muffled, there was (to me) hardly any detail. all i have to say is I LOVE MY 650s! No one can take them away from me! rating: now tell about your experiences =).
