Shure E3C-N-EFS Black Lightweight Sound Isolating Earphones, Extended-Frequency Soundstage.

Shure's lightest earphone design yet, the smaller E3c is a perfect fit for small ears, and provides sound isolation while delivering a brighter, crisper, more detailed sound experience.

Originally developed for professional musicians, the E3c combines WideBand MicroDriver technology with a sound isolating design to deliver rich, detailed sound with improved high end while blocking outside noise, ideal for optimizing your listening experience with portable MP3, DVD, and CD players as well as all other audio sources.

The E3c's in ear design works like an earplug to block background noise naturally. This enables you to listen comfortably at lower volumes-even in loud environments. And unlike bulky headphones utilizing active noise cancellation technology, no artifacts are introduced into your listening experience. Sound isolating earphones are also much smaller and don't require batteries.

The E3c's speakers are constructed with studio-grade components to produce exceptional audio clarity, delivering detailed highs and enhanced bass that allows you to hear parts of your music you've never heard before .

Because every ear is different, E3c Earphones come with a pair of disposable Foam Sleeves, three pairs (small, medium, large) of Flex Sleeves, and three pairs of Soft Flex Sleeves (small, medium, large) to ensure the ideal personalized fit.

The soft, flexible sleeves in the Fit Kit gently contour to the inside of your ear to create a comfortable, secure fit, so that the earphones don't fall out while exercising. The E3c's are also compatible with custom-molded sleeves, madeby a hearing specialist, for the ultimate in fit and comfort.

Weighing only 0.9 oz (28g), the E3c is among the lightest earphones on the market. The E3c comes with a stylish, compact carrying case. The cable spool inside provides a convenient, tangle-free way to store your earphones. Every E3c purchased comes with a two-year limited warranty on materials and workmanship.
