Out of the box, I'm diggin these. Last decent IEMs I had were re0s which broke quite a while ago.
The bass is definitely stronger on these and extends lower.
Pre break-in, there is detail but not as much separation as I had with the RE0s. I'm sure it'll change with some run-time.
And of course when I give them a better input. Running off a 120gb zune isn't exactly a hi-fi setup
Can't wait to get the DX50 to see how these get along, and also looking forward to my BA200s coming to compare to these.
I don't like the sound out of the DX50 somethings not right
