well among that praising (or non bashing) you obviously did not see the 16ohm impedance,let me guess thats a typo aswell and most likely 160ohm no?? the fact is its not just the frequency range its a number of things that dont paint a good impression, and its the impression they give that we are bashing.
No, thats not a typo. Look at denons, audio technica, grado, some AKGs. Are you trying to suggest that low impedance somehow equates to low quality? Yes I looked up on the jp site, 60mW is not a typo. However, I still believe that may be because of the booster. Yes, you heard. My theory was right. Check this out:
Look towards the bottom, there is a picture of the "booster" which you may click to enlarge. And under it is the caption "The booster attachment which corresponds to the output level of the various equipment"
My guess is that the booster can't handle more than 60mW. And, sony realizes that 90% of all devices that headphones are plugged into struggle to put out 5 or 10mw.
My guess is that once the booster is removed, you will be opened up to the possibility of hooking the headphones up to a much nicer amp. I could be wrong (and even then it is still possible that it will sound great), but it seems likely to me.
