Why In-Ear Technology
In-ear earphones provide sound quality far beyond the technical ability of even the most expensive earbuds, and provide isolation that's superior to even the best headphones. By creating an exact fit between the sound source and your ear canal, unwanted sounds are blocked out while the music comes straight in.
What Are In-Ear Earphones
In-ear earphones are a special type of 'isolating' earphone, originally developed to allow musicians to hear their own performance in loud onstage environments. In-ear earphones work by using soft, pliable sleeves to seal out background noise, allowing small, high-performance drivers (speakers) to deliver incredibly precise sound directly to the ear. Shure now makes these professional-quality earphones available for use with portable audio or video devices such as CD, MP3 and DVD players.
How Are In-Ear Earphones Different from Other Headphones
The primary difference is their listening position - where they are worn in relation to your ear. Headphones generally enclose your ear or rest on top of it. Regular earphones (like the earbuds often packaged with CD players) sit on the outside of the ear. In-ear earphones are different. They are designed to fit inside your ear canal, where they create the isolated listening area responsible for their unique acoustic properties.
How Do In-Ear Earphones Work
By selecting from an assortment of soft, flexible sleeves, you're able to personalize the fit of the in-ear earphones to your ears. The sleeves conform to the unique shape of your ear, creating a space inside your ear that is isolated from the noise around you.
Why is Isolation Important
In-ear isolation makes it possible to hear greater detail at a lower volume than is possible with earbuds or most headphones intended for portable use. Lower-volume listening means less fatigue over extended periods, and is safer than trying to overcome background noise by turning up the volume. This makes isolating in-ear earphones the ideal choice for commuting, travel, exercise, study, or work - any activity where you desire portable, hi-fidelity sound.
Is Isolation Different from Noise Cancellation
The isolating seal created by an in-ear earphone physically blocks most frequencies of background noise and is a simple, natural form of noise attenuation. Active noise cancellation 'headphones' are generally larger, heavier and battery-driven. The active cancellation process negates selected frequencies through a complex process that can even introduce unwanted artifacts into the resulting audio. The natural noise attenuation properties of a properly fitted in-ear earphone can rival or exceed the performance of even the most expensive active noise cancellation alternatives.
