So have like 100 hours on the stock 90s, did the reverse pad mod but reversed it back (reversals galore). They sound fine, excellent in fact, out of my iPhone 5, but...I need to EQ them via Onkyo HF app, taking the bass up and the 8k freq down a small amount. With that, excellent with the HP out on the iPhone 5. Haven't plugged them into my C&C BH/iPod Classic combo yet. Excellent phones, design is a bit annoying, but on balance well worth the $69 I paid. Not replacing my X1s however, just prefer the Fidelios for several different reason, sound sig being just one.
Going to keep burning them in with the Auvio cable, another 100 hours, see if things sound any different. Also hard to power on the IP5, but enough volume without hitting max. Close though.
Just too lazy, concerned about modding. Guess I will miss that boat.
