Uptowns mostly catched my eye because I could buy them now for about the same price I got Downtowns half an year earlier. I was a bit unclear, but I don't need neither absolute clarity nor turbofast cans. Some records like Lapko's discography just deteriorates into cacophony of barely distinguishable instruments. I don't know how to describe it, but on HM5 for example they sound fine. I mentioned rock because I know you can't find good jacks of all trades for this price, but this should give some insight on my taste.
I will check out the KNS8400, but on the first sight the headband seems to be the type that makes your head look three times bigger. That's the look I try to avoid. Also HD25 and DT1350 are on my 'will get someday' -list, but as a student it feels like I could use those 200e more wisely.
Ya check them out. I think your ears will be so happy you won't care what you look like.
The uptowns to me are a great sounding headphone that do have their flaws. Specifically the fact you are missing some detail in the mids but at the same time somehow they don't sound muffled or too laid back. For the money they are great. I can't get that link to play on my ipad but I can't see having the problem you described with those. If you have access to them for cheap they are well worth it. If they don't work out they can easily be re-sold to a non audiophile friend since most people will find them to sound great.
