OP:
Ignore frequency specs; trust your ears.

I wont be able to do any testing in my country(Which doesnt carry these higher end phones,or are selling them at extorting prices) so the best i can do is to read many reviews and try to import them from within my region in asia.

To Zipdisk:I searched wiki before and they gave me a huge chunk of information not directly relating to Earphone specs,but thank you for the quick definitions.

Now i know i cant judge a pair of earphones by their frequency,which was what i used as gauge before being enlightened.Sony ones really have very high frequency ranges.
The frequency range list was interesting

Thanks for the answer.

A bit of research and I think I find what I am looking for:
3 dB change is indeed doubling/halving of the intensity of a sound (or power on an amp), but only increase/decrease 1/2 of the voltage (6dB will be doubling/halfing). However, it seems that human perceive 10dB as doubling/halfing in loudness. So to answer my own question, 3dB is measured as doubling/halfing in SPL, but only perceived as about 30% increase/decrease in loudness.

They can say that it's 5hz to 35khz but if they don't say +/- whatever db, for all we know it could be within 20db.

So those numbers literally mean nothing at all.
Exactly.

To the OP, headphone specs and numbers are pointless. Why? Cause even if you look at the cheapy walmart headphones, according to their specs, they have a range of 10-35,000 hz...they very well may, but they still sound like crap. So really...it's all garbage and just something to circle jerk over if you're a spec-head...but in reality, it can still sound like crap....so actually listening to them is all you can really do.
