I'm having the same exact feeling. I love these headphone, but it's just too bright so it's tiresome to listen to for long.
Now burning it in to see if it helps.
Yes i agree with you i used them they are really pretty and congrats.
I didn't find much bright, maybe they are fatiguing while listening to some power noise music, otherwise I find them fine.
I just use them for jogging (one half hour, and then I forget them).
