    So, I decided to do a little build, make some over ear headphones with Koss KC75 Drivers and another headphones headband.
    See below post for those measurements
    But before do that, I decided to measure both.

    The Koss cost $13, the others (Kanen I39) Cost $17

    Subjective:
    The Kanen sound pretty bad. Not as bad as I thought they would be, but they just have a distant quality, and overall are just not too good. I would expect this or worse for this price, but thats where the Koss change the picture. However the Kanen feel pretty solidly built for the price, fold, adjust, have a braided cable, with remote and mic. More than I thought for this price. They have pretty good comfort, low clamp pressure, possibly too low. I find the Koss more comfortable.

    The Koss blew me away. People said these were great bang/buck, but I didnt expect this much. They have nice upper/mid bass, dont extend extremly low, but I wouldent think they would. I find them much more comfortable than I thought, infact with the mounting system and the low weight, I can forget they are on my head. But no isolation, as they are open back and lightly on ear. Cable feels pretty cheap though.
    Do note I like treble heavy headphones, which these certainly are. I like Grados, if that tells you anything.

    Objective:
    Measurement system is the SBAF recomended mic build thing, with a M-Audio Preamp. Mic is on a leather coupler with a felt ear shape.
    Headphones fed by GO450.

    FR:
    (I labeled the Kanen as "Bad")

    Very nice measurements from the KSC's on your rig. Close to how I hear em. Got any other cans?

    Edit: Nevermind on the question, just saw your other thread.

    Glad to see others think my rig is accurate. Only thing I need to work on is it May increase the bass on over ear headphones.

    I combined the two, putting the koss drivers in the cheap Chinese stuff. Didn't have any dampening stuff on hand, so just put some felt in there. It actually sounds better than I thought.
