Perfect for audio enthusiasts looking to upgrade their earphones, the i2c 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 i2c'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: Dynamic MicroDrivers
The i2c's speakers are constructed with the same studio-grade components as our award-winning E Series Earphones, producing outstanding audio clarity that allows you to hear your music like never before.

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.

Dual or Single Connector Versions
 Choose between a dual connector version (i2c) which allows you to plug into both a portable audio player and a mobile phone-or a single connector version (i2c-t) that's engineered for compatibility with the Treo™ 650 and 700W. Click here to check Phone Compatibility.

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 i2c comes with a stylish, compact carrying case, providing a convenient, tangle-free way to store your earphones.

Every i2c purchased comes with a two-year limited warranty on materials and workmanship. (See warranty information)
