A great part of Shure headphones comes from the sound isolation technology that works with these headphones. Sound isolation is used by Shure to help with getting a connection between the ears and the sounds coming out of the headphones to work. This is different from noise cancellation in that no artificial sounds are created in addition to the sounds from the headphones.
If you are searching for a pair of headphones that do a good job on blocking noise then you might want to consider investing in a pair of sound isolation systems earphones. These types of earphones provide sound quality way above even the most expensive headphones or earbuds. They work by creating a secure fit between the device producing the sound and your ear canal. Background noise is blocked out and the music is the only thing you will hear.
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 systems ear cups. The result is a greater degree of sound isolation and superior sound quality for your music.
