Terrific write-up @Ichos ! We're certainly in agreement about the dottedline to the HD 650 tuning with regards to bass and mids—the all-arounder most can groove with. Can't wait to see more photos from your sessions. Thanks again!

Thank you very much!

Thx for this review! Is it possible that for you to compare the ie600 against the ier m9? In my country the m9 and ie600 had similar prices so I wanted to hear out some advices. Thx

Thank you very much.
I am sorry but I don't own or have any experience with the ier m9.

A very good review. IE900 has made a few of my friends go gaga over it. IE600 is yet to come and if opportunity permits I'll hear them both. I think there are a few typos in the vs section where you compare IE600 with FD7. You have typed IE900 instead of IE600 to my understanding. Or I am understanding it all wrong and you typed correctly. In that case please ignore the later part of my comment.

Thank you very much for your kind words and pointing out the typos.
I have corrected them.

Nice review thanks !

Thank you, it was my pleasure to review them!

This is the FDX and it is so kitch that in the end i like it.
It is s a statement of art!

Imagine yourself as a consumer, you see all these attractive, gorgeous chi-fi solutions with multicolors resin, stainless steel, chrome, and then you get ... THIS from Sennheiser. lol
