Well if amps have the same function as headphones, why is there a need for them? How much does a decent amp cost? I mean why would you go to the hassle of buying an inferior pair of headphones and upgrade it with an amp instead of just going out to buy a higher end headphone.   This is...

  So basically, as i understand from your post, an equipment, such as a headphone, would "tune" the frequencies of a particular note.  For e.g an "A" note will always be of the same pitch (that is A), but different headphones would bring out different characteristics of the "A" note.  A...

Some theoretical stuff written there, but i get what you guys mean   But when i read reviews about high, mids and lows, i could simply assume that these terms refer to high pitches, meduim pitch and low pitches right? I mean, that would be what they are talking about

  Thanks for that thread link, it should help a lot, will bookmark and take a look later.

Hi all, i'm new in buying higher end earphones so i'm looking for some help.  I'm looking for a pair of noise cancelling earphones for my sony phone under $100.  I've looked around the internet and saw brands like grado, seinhesser and shure.  Most of them are out of my budget, shure is closer...
