Noise reduction headphones are not the same as noise cancellation headphones. The Direct Sound Extreme Isolation Headphones are better classified as noise reduction headphones because they do not use electronics to actively cancel ambient noise. Instead, the Direct Sound headphones physically block sound by reflecting the sound away from your ears while enclosing your ears in patented sound isolating ear cups. The result is a greater degree of sound isolation and superior sound quality for your music.
Why Noise Reduction Headphones Sound Better
Most noise cancelling headphones use electronics to “listen” to the sound around you so that they can produce an “opposite” sound wave to cancel the sound inside the ear cups. This is called active noise cancellation because the headphones are actively destroying incoming sound with a cancelling sound wave. For audiophiles like us, the major problem with this type of noise reduction is that the “canceling” sound wave which is intended to block the ambient noise also destroys the music you are actually trying to listen to. There’s simply no way around it. Let’s take a simple sound frequency as an example. Suppose there is an ambient noise at 1000 Hz around you. So your active noise cancellation headphones produce a sound wave that blocks that frequency inside of your ear cups. But what if the music you are listening to also has a sound at 1000 Hz. That frequency in your music is then canceled as well. So now you have canceled sound you actually do want to hear.
The problem doesn’t stop there. The folks that make active noise cancellation headphones know this so they build their headphones to artificially boost certain sound frequencies in your music because they know that the noise cancellation electronics are going to be destroying those frequencies. Now your music is totally distorted from what the artists intended for you to hear and, instead, it sound like an approximation of what your headphones company wants you to hear. The end result is very unsatisfying.
There is yet another problem with active noise cancellation headphones. The “cancelling” sound waves that they produce are not silent. If you put on a pair of active noise cancellation headphones and simply turn on the noise cancellation electronics you are going to hear a very disorienting, swooshing noise. This is the sound of the “cancelling” sound waves inside of your ear cups. This swooshing, static noise does not go away when you start playing your music. So you are going to be hearing a distracting and annoying static noise in the background of EVERYTHING you listen to. This destroys the quality of your music and makes it sound like you are listening to an old record or a dubbed tape or something. You will not be getting the crystal clear audio that you could be getting.
Noise Reduction Headphones Are Crystal Clear
Noise reduction headphones do not use electronics to block noise and, therefore, do not introduce any swooshing static noise into your music and they do not destroy any of the audio frequencies in your music. The result is crystal clear audio the way the artists intended for you to hear it.
Noise Reduction Headphones Block More Noise
Direct Sound Extreme Isolation Headphones are noise reduction headphones and they block more noise and a wider range of sound frequencies than active noise cancellation headphones. The average set of active noise cancellation headphones blocks about 12 – 17 dB of noise. Even the really expensive, $300 active noise cancellation headphones only block about 17 – 19 dB of noise. Direct Sound Extreme Isolation headphones block an average of 29 dB of sound. If that doesn’t seem like a big difference, keep in mind that something that is 10 dB louder is twice as loud. This means these headphones will block what sounds like twice as much noise.
In addition to reducing sound be a greater number of decibels, these headphones block a wider range of sound as well. Active noise cancellation headphones are only effective at blocking consistent, rumbling noises like engine noise on an airplane. They do not do very well blocking short bursts of noise like phones ringing or people talking. This is because the electronics in the headphones do not have enough time to calculate a “cancelling” sound wave for these short bursts of noise.
Noise reduction headphones, on the other hand, are excellent for blocking crying babies, talking, barking dogs and other types of short burst noises because they work be reflecting the sound away from your ears. Passive noise reduction headphones do not need to calculate anything, instead they instantly reflect the noise away from your ears.
So, in summary here is a list of reasons why
our noise reduction headphones are better than active noise cancellation
- Better sound quality for your music
- Blocks more decibels of sound
- Blocks a wider range of sound
- Effective at block short bursts of sound like TVs, talking, dogs barking, etc.
- Do not require batteries
- More durable
- Better value for your money
