So I have been doing some research and am deciding on getting the mdr-v6 or the mdr-7506. I found out that the frequency responce of the v6's is 5-30,000 Hz and the frequency responce of the 7506's is just 10-20,000 Hz, which doesn't make sense to me. The 7506's are intended for professional use so wouldn't it make sense to give them a broader frequency response? And my other question is is there much of difference between the 10-20k and 5-30k Hz response since the human ear can only distinguish sounds between 45-20k Hz?
And is there any other info anyone can give me to help me make my decision between these two headphones? Thank you!
