Gopal , it's not because you can't hear below 25hz that it's not a good thing that the headphones produce frequencies below that.
I read a book and it explains why the wide range of frequencies is important.
They did some tests with sounds and stuff where they compared the sounds with the frequencies below 20 hz and above 22 khz to the same sounds without those frequencies and there was an audible difference.
The theory was : tho we can't hear those frequencies , they have an effect on the frequencies we can hear , they slightly change them , so if we remove those frequencies , the sounds change.
Not that i'll ever be able to hear the difference , but hey , i ain't no mixing or mastering engineer you know.
