Ideal for the business traveler or on-the-go audiophile, the i4c provides you with the convenience of either listening to your music or answering a call on your mobile phone. Standard versions work with portable audio players and most cell phones. A single connector version is available for use with the Treo™ 650 and 700W.

Sound Isolating Technology
The i4c'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. Outside noise is reduced by 30-37 dB, so no matter how noisy it gets on the train or at the airport, you can always hear your music-OR your conversation.

Speaker Type: High-Definition Driver with Tuned Port Technology
The i4c features the same High-Definition Drivers with Tuned Port Technology as our award-winning E4c model-for incredible audio reproduction, complete with brilliant highs. Additionally, i4c's Tuned Port Technology improves airflow around the driver to deliver professional-grade sound with extended bass response.

VoicePort Inline Microphone
The VoicePort Inline Microphone is acoustically tuned to filter out background noise and minimize wind noise-ensuring that callers hear you clearly even in the noisiest situations.

Multi-Function Control Switch

Dual Connector (i4c)
Conveniently switch between listening to music and fielding phone calls, adjust music volume, and mute the VoicePort Inline Microphone.

Personal Fit Kit
Because every ear is different, i4c Earphones come with three pairs (small, medium, large) of disposable Foam Sleeves, three pairs (small, medium, large) of Flex Sleeves, and three pairs (small, medium, large) of Soft Flex Sleeves, to ensure the ideal personalized fit.

Secure In Ear Design
The soft, flexible sleeves in the Fit Kit gently contour to the inside of the ear for a comfortable, secure fit so that the earphones don't fall out -even while exercising or hurrying to make your flight.

Carrying Case
The i4c comes with a stylish, compact carrying case, providing a convenient, tangle-free way to store your earphones.

2-Year Limited Warranty
Every i4c purchased comes with a two-year limited warranty on materials and workmanship.
