Okay, so I bought the UE4000 and it first I didn't like them. My iPod Nano 7G isn't providing enough power in my opinion. When I used it with my HTC Sensation XE with an equalizer it sounded WAY better. But I still don't think the bass is "fat" enough. I'm used to the bass of my Sennheiser...

  That's some nice advice! So you would say, go for the UE4000, since these have nice sound quality and are the cheapest of all 4? And team it up with a Fiio E6 in case the bass lacks.

Hey Billson! So you discourage me to buy one of the XB series? The UE4000 looks pretty cool, I take a look!     @parall3l: Sennheisers are always good stuff, I'll take a look into them! EDIT: The Sennheisers are too expensive for me. They sell them for €300 here in Holland, so that's a but...

Hi guys!   After searching the web for a very long time, I'm left desperate with all the possibilities out there. So I decided to ask you guys for advice!   Until now I have only used my Sennheiser CX-300II in-ears to listen my music. (on my iPod or HTC Sensation XE) I have decided to add...
