Shure E3c, E3g Sound Isolating Earphones

E3c in White, E3g in Black

E3c and E3g ARE the same earphones. See Shure.com FAQ.

Originally developed for professional musicians, the E3c/E3g 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.

Sound Isolating Technology
The 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. Demo.

WideBand MicroDrivers
The 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.

Secure In Ear Design
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.

Carry Case
Stylish, compact carrying case. The cable spooler inside provides a convenient, tangle-free way to store your earphones.
