Shure's sound-isolating SCL2 earphones in black.

Sound isolating earphones provide sound quality far beyond the technical ability of the most expensive earbuds and isolation that's superior to the best headphones. By creating a secure fit between the sound source and your ear canal, unwanted background noise is blocked out while the music comes straight in.

They provide a comfortable fit thanks to the three sizes of three different included sleeves--orange foam, clear and gray flex. Experiment with the size and style that creates the best fit for you--a good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear. A durable and compact carrying case is included with the SCL2 to provide a convenient, tangle-free solution to store your earphones.

Sound Isolating Technology

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. Sound isolating earphones are different. They are designed to fit inside your ear canal, where they create an isolated listening area that is responsible for their superior acoustic properties.

Sound isolating earphones were originally developed as Personal Monitor Systems to allow musicians to hear their own performances in loud onstage environments. Sound isolating earphones work by using soft, pliable sleeves to block background noise, allowing small, high-performance drivers to deliver incredibly precise sound directly to the ear.

Is isolation different from noise cancellation?
The seal created by a sound isolating earphone physically blocks most frequencies of background noise. 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 sound isolation properties of a properly fitted in ear earphone exceeds the performance of even the most expensive active noise cancellation alternatives.

How do in ear sound isolating earphones work?
By selecting from an assortment of included soft, flexible sleeves, you're able to personalize the fit of the earphones to your ears. The sleeves conform to the unique shape of your ear, creating a seal that isolates you from ambient noise.

Why is isolation important?
Sound 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 sound isolating earphones the ideal choice for commuting, travel, exercise, study, or work--any activity where you desire portable, hi-fidelity sound.
