This is the third Sennheiser headphone I own. I had MX365 and OMX980 before. It's my first over-ear Sennheiser headphone, exactly the HD650.
Standard Sennheiser sound, smooth treble and solid bass. Compare to my beyerdynamic T90, the HD6XX is less definition, veiled treble but it's more suitable for pop music.
It's a good deal at that price 200. Thank you, Massdrop!
