If I had not been awaken from by zoned-out enjoyment, I would have been listening for hours for my initial test. The sound is incredible, certainly for the bass, but the higher notes are still very clear as well. I'm actually finding that I need to turn my volume settings down a bit because of the strong signal, not that I mind at all. The cord is exactly how I'd like it, very long and very sturdy. The screw-on jack adapter looks very nice too, but I have not yet tested it. They are a little tight for my big head, but I'm already mostly used to it.Having worked with professional sound equipment myself, it certainly doesn't give you ~that~ level of quality, but it does come pretty close. It is definitely very high quality for the price. I would highly recommend it.
