Thanks for the prompt response. If I do end up going with these, is it true that you need to EQ the treble down quite a bit? I can do it, but I would rather have something that can get a reasonably even response on its own so I don't have to mess with the EQ when I switch devices or use someone else's. I have heard that the upper range is about 8 db too strong.
You may well want to EQ them to deal with the upper-mids/lower-highs. I use with them with no EQ. Simply put--there are limitations for what you can get for $50. (Other than a clone) Show me another $50 to $60 can you can get with the bass, sound stage and overall frequency response of the Superlux. If you want a good mid-centric $50-ish closed can instead, get the Koss ProDJ100
