I've read some of this thread, comparisons bet the 400 and 600, but wonder if anyone has compared them to either the ex1000 or mdr 7550(which I own.) I'm trying to figure out if either the 400 or 600 would be a side grade or upgrade to my 7550 and a signature comparison. I'm also trying to figure out if the 400/700 balanced combo comes closer to the 600 unbalanced. Any thoughts or links would be sincerely appreciated!
theres a youtube reviewer that i think used ur mdr 7550
heres some links
his review on the re400
his review on the mdr7550 wow he also has the ex1000 perfect!
this is somewhat related he compare the gr07 with the mdr7550 and the re400 so you can find some information there regarding the re400
