Listening to the Comet right now as type this. I like the signature out of the box. Used the medium spinfits and swapped out the cable. While the quality of the cable that came with them was not bad, just can't do the controls portion. Using a Norne Vorpal instead. Using over the ear and found was more difficult to get the exact placement correct. Once I found that place, the sound was rich and full. The bass had nice impact, mids were sweet and robust. The treble was spot on but saw it a little spiky. Could've been the files I was using. Could be some poor quality mixed in. The hi-res stuff was sharp and sibilant-free. Using my X3iii as a source. So after an hour, I find myself wanting to hear more. I think Ken nailed it with the tuning. I am using this to replace the IT01 that my son inherited from me. As I get more adjusted to the fit and sound, I think this will be a nice go to for me. Very glad I jumped on board with this.
