In sleek black, to go with some of today's newest MP3 and other audio players. 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. The E3c comes with a stylish, compact carrying case. The cable spool inside provides a convenient, tangle-free way to store your earphones.
