Hi, I sniped some K340 on German ebay... and I'm testing them atm. They have been recabled by the former owner with a somewhat cheap straight cable (5m, lol) To my ears it sounds like the right side is a tad louder when it comes to mids + highs So I was wondering if his job was screwing with the electec-drivers. I thought it might be the song I was listening but I'm not quite sure after testing with several other tracks. So I tried downloading a mono mp3 and equalized it a bit to make the highs more prominent than everything else. (As far as I know, they tweet from +4khz upwards) I got my brother to listen to them but I made a mistake and told him that I believe the right side was louder... he agreed. Now I'm testing with audacity with 600hz equal sound 3khz right side louder 9khz right sides equal 12khz left side louder 15khz left side louder 16khz both sides equal 17khz about the same all this was measured with removing one cup side and switching ears... and I'm not sure if any measurement was right at all. My mind might be playing tricks with me... but is there a way to physically see/test if any driver is broken/damaged? here have a pic as a tiny thanks.
