Under what specifications does the sound quality of a pair of earphones mostly depend?

Frequency range or something else?

 

 

Thanks,

I can’t give you a definitive answer to this, but I can say that the frequency response listed by headphone manufacturers is not the be-all and end-all. I’ve had headphones that listed a very wide freq. response that clearly did not let me hear the whole range. 

My Sony MDR-V150 headphones promised “exceptionally clear sound for professional and high fidelity applications” .HA!!!  That did not prove to be the case…I had to boost the upper reaches with custom EQ considerably to acheive clarity, although they did not lack in the upper bass-lower mids. I had a cheap pair of Maxell headphones that said 20hz-20khz on the packaging…they did sound slightly better than AM radio, but not by much.

Hopefully someone with more technical expertise has a litlte more knowledge here, I’d be curious about what they might say too.
