This review is from: Cyber Acoustics ACM-800 Noise Cancelling Headphones
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....

I got these as a sad gift -
The overall sound quality is quite bad (when NC - Noise Cancellaton-is turned off). Not much low frequency and minimal high frequency content. So purely as headphones - they fall at the bottom of the heap.
With NC turned on, there is some amplification of the sound - so it sounds louder. The NC effect itself - well - its kind of works, but not much. Probably about 20 percent of the noise is taken care of. Don't even try comparing the performance of the Bose to these (I did so - using a co-passengers Bose QC3 - and it was a revelation - one works beautifully and this one barely does so). I plan to get a pair of Panasonic RPHC300 now (Since I don't have $300 to burn).
I am curious how the NC effect is implemented for the left and right earpieces. There is no wire that connects the right side (with the battery and NC electronics) with the left earpiece. Go figure this one out :). I have some ideas - but that would mean this is not a stereo headset. Too lazy to experiment further with this piece of junk.
The good thing is they fold quite well....
