Yesterday i tried the SE846, K3003 and IE800 and compared all of them with my Ultimate ears 900.
I acutally liked the UE 900 most and the SE846 least. I didn't even like the Shure SE846.
Check what i just wrote in the SE846 forum.
I didn't have the guts to tell them i liked the UE900 most or they would probably think i worked for UE or something :D
