Direct Sound Extreme Isolation Headphones
I’ve been checking out the Direct Sound Extreme Isolation Headphones from QuietHeadphones.com and these headphones actually do work. If you play the free white noise MP3 through these headphones you really can block out virtually all background noise. When I firsted started looking into noise cancelation and noise reduction headphones I was hoping to find something that would be like pushing the mute button on the outside world. I quickly came to realize that it is simply impossible to block all noise with earplugs or headphones. Of course, first you try all the big brand names which use active noise cancelation which samples the ambient noise in your environment with little microphones then tries to produce an “opposite” soundwave in your earcups to block the noise. This technique of noise cancelation is very effective if the noise you are trying to block is a constant hummning noise like an airplane engine or an air conditioner. The electronics in the headphones can figure out what the right canceling soundwave to produce is, then it can just keep producing that same cancelation wave to cancel out the background noise. But if you are in an environment with spikey background noises like talking, doors slamming, phones ringing, etc. the active noise cancelation headphones don’t work very well. The electronics aren’t able to figure out what the propper “canceling” sound wave is fast enough and consequently you don’t get very much noise cancelation at all. Also worth mentioning is that these active noise cancelation headphones all require batteries. So if you use your headphones every day, expect be buying batteries about every month.
An alternative solution is to go with a set of passive noise reduction headphones like the Direct Sound EX-29 Extreme Isolation Headphones. These headphones work by physically blocking sound from reaching your ears. The earcups are packed with high-fidelity, studio quality speakers and a patented noise isolation foam. They have a closed back design so sound can’t get to your ears. With this sytle of noise blocking, these headphones can block both constant noises like airplane engine noise as well as spikey noises like talking and phones ringing. They also block more noise than active noise cancelation headphones. Active noise cancelation headphones block about 17dB of sound where as the Direct Sound headphones block 29dB of sound. Active noise cancelation headphones have a targeted range and type of sound that they are designed to combat. The Direct Sound headphones block sound across the entire sound spectrum.
Some other advantages to these passive noise reduction headphones is that they don’t use batteries and they don’t leak sound. Since they don’t use electronics to actively cancel sound, they don’t need batteries. This means you don’t have to keep buying and replacing batteries which is certainly a cost to consider when choosing your headphones. Also, have you ever been sitting at work or near someone using headphones and you can hear the drums and rhythm of the music they are listening too. Sometimes you can pretty much hear the entire song like their headphones are little annoying radios. The Direct Sound headphones do not have that problem. Not only do they keep the outside sound away from your ears, they keep your music in. Stage and recording musicians use these headphones so that the sound from their headphones doesn’t leak into their mic. For personal use, it’s nice knowing that you aren’t bothering the peopel around you. As a fun test you can put on your Direct Sound headphones and start listening to some music at a comfortable volume. Then take of the headphones and press the earcups together. You will be astonished that you can’t hear any music leaking out. It’s really an interesting test to try.
