I am also selling my beloved SM3 as no longer use them because I bought a pair of SE846 I use for now.
Don't do it man, you'll be sorry for the rest of your life... How can you sell you baby???!!! Haven't heard the SE846 but I just bet it won't sound anything like the SM3 . The SM3 is pure magic and always will be. Had a long good session with it tonight and it blows my mind. I love it and always will. Tonight all my other gear feel like mistresses, younger and sexier but the SM3 is the real deal.
