HeadhunterI'm not sure. My understanding is that, even though these headphones have a low impedance at 62 ohms, they require a lot of current to actually push the sound. I've read that, without the proper power being provided, everything sounds thin. If you can, get your hands on an amp and try them out on that to see if it makes a difference. You could even pick up a cheap, mobile one. The Shiit Fulla is on Amazon for $59. I don't have any personal experience with this though. This is going to be my first experience with headphones that aren't cheap ones from walmart. I've just done a lot of reading.
