Query: Good job for the price

Obviously these headphones are not like the Bose ones, but they do a good job. They work in three ways:- They fit closely to the ears, cutting out high frequencies- They suppress mid-low frequencies actively- They raise the mid/low frequency spectrum of the music.Being aimed at "mechanical noise", they get rid of most of the server-fan noise in my office and reduce also a bit talking/typing (talking becomes inaudiable with medium-level music).The main con is that the increased mid/low frequencies can get annoying - so I simply adjust the equalizer of my mp3 player. The joint that make them foldable might get annoying, depending on how you wear them and on how mych cushioning is provided by your hair. Also for some people the leather cushioning might get a bit hot on the ears, but they only "fit on" and don't "hug" the ears.Overall the music quality is ok, and they're a good investment if you don't look for perfection or you don't want to spend >$100.
