Noise reduction Dr Sre monster beats are not just like noise cancellation headphones. The Direct Sound Extreme Isolation Earphones are better classified as noise reduction earphones because they usually do not use electronics to actively delete ambient sound. Rather, the Direct Sound cans physically block sound while enclosing your ears in patented sound isolating ear cups by reflecting the sound away from your ears. The result is a greater degree of isolation that is sound and superior sound quality for the music.
For audiophiles like us, the major difficulty with such a noise reduction is the “canceling” sound wave which is thought to block the ambient noise also destroys the music you’re really trying to listen to. There is just no way around it. Let’s consider a simple sound frequency as an example. Suppose there’s an ambient noise at 1000 Hz. Your active noise cancellation Dr Sre monster beats create a sound wave that blocks that frequency inside of your ear cups. But imagine if the music you’re listening to also has sound. That frequency in your music is subsequently canceled as well. So now you have canceled sound you really do need to hear.
The difficulty doesn’t stop there. The people that make active noise cancellation earphones know this so they assemble their Dr Sre monster beats to artificially boost specific sound frequencies in your music because they know the noise cancellation electronics will be destroying those frequencies. The end result is very unsatisfying.
There is still another problem with active noise cancellation earphones. The “cancelling” sound waves that the artists create are not hushed. If you simply turn on the noise cancellation electronics and put on a pair of active noise cancellation cans you happen to be going to hear a really disorienting, swooshing sound. That is the sound of the “cancelling” sound waves inside of your ear cups. This swooshing, electrostatic noise will not go away when you begin playing with your music. So you will be hearing a an irritating and distracting electrostatic noise in the background of EVERYTHING you listen to. This makes it seem like you’re listening to an old record or a dubbed tape or something and destroys the quality. You may not be getting the crystal clear sound that you could be getting.
