I've started with some very cheap koss headphones, moved up to Sen 515 and then after i got a better job i decided to "conquer" the top of the closed headphones (i listen to them in my workplace).
So i got the TH900.
Lately i've just wanted to try new types of headphones and see if the open headphones are really better sounding.. So once i saw the black friday deal from headamp it was a done deal for me.. Lcd 3 are way too expensive for me anyways, and the lcd 2 with the discount were a great catch..
I find them very smooth, very fun to listen to.. the bass is just phenomenal and accurate and i think that they are less fatiguing than the th900.
However, they are less comfortable and open, so people around me can hear my music (it's good music so i dont care
)
