I will be looking to buy a headphone which can block out outside noise(high frequency, low etc) as long as it really blocks out the noise and nobody really disturb me. Can anyone point me to some tutorials/faqs where I can learn all these stuff and which stuff is good for me? Thanks a lot. I did a search on noise cancelling headphones here but i did not see any info on noise cancelling headphones(or maybe I missed it)
