also anyone got any particular songs they find mindblowing on this set up?

Got the same set-up... big fan! Any trouble with the e9 and the fuzziness in sound?

Estreeter and Nickel Zhang make good points... fiio product are a steal for how much they cost, but they do suffer from some quality inconsitencies here and there.    I have heard of issues with the headphone jack with the e7, fortunately I have mine docked into the e9, and dont need to use...

From what I've heard the X10's are pretty reliable, my friend has had a pair for the last year and he travels frequently meaning alot of stuffing into his backpack. They still work and feel great... I listened to the recently and love the sound. Dat bass. Not to mention dat comfort. 

I have the m2 model and Im surprised at how detailed the sound is out of them. I can only imagine that Brainwavz reproduced or improved upon that in the m4s. I also am a fan of the punchy bass that most brainwavs produce. Not to mention at their price range is AMAZING!

Its surprising how much bass gets pumped out of these guys. I currently have the 650's with the fio e9 headphone amp and the e7 dac. Any one else with this set up? Thoughts?

I havent listened to the ultrasones or the xfades, so I cant tell you about those. But as far ass the 770's go... I love em. They definitely have an above average soundstage to them, meaning spacial feel to the sound will be accurate. Their bass is amazing as Im sure youve heard, and I am a self...

The DT880's are weird as far as isolation goes since they are half open air and closed, but Id say you would find their isolation good - very good.
