Yeah, the MC5 would be a very good one but even your updated budget is a bit tight for it. All the other things I would recommend won't be available from your local dealers so you'll run into the same issues with paying/processing/shipping as with the inexpensive VSonics.
I guess in that case what I'd do is go with the MH1 (make sure it's the right version for you device and/or you have the appropriate adapter) and lower the bass via EQ to try and balance it out.
Yeah I really don't want to spend that much and I can't see the price coming down. I've managed to find some UE600s for well within my budget however, only £20 refurbed, so will these be better than the XBA 1 and MH1? Your review here gives them almost as high score as the RE-400 and much more than the Etys, but the actual tone of the review didn't sound as positive as the score, perhaps as you were comparing them to more high end IEMs. Basicaly would UE600s be my best bet at this price or are they no better than ehat I've got? Thanks for all your help, this should definitely be my final question!
