Shure i3cT Sound Isolating Earphones with Connector for the Treo

Switch seamlessly between answering your Treo and rocking out to your favorite music! The I3cT delivers extended-range audio via WideBand MicroDriver technology with the added convenience of integrated communication capabilities. The multi-function control switch allows you to choose between listening to a portable audio device and/or answering a call on your phone. The VoicePort (tm) inline microphone filters out background noise, ensuring that callers hear you loud and clear. The 2-function control pod includes a volume control and microphone mute button. The I3cT uses the same technology as Shure's award winning ESeries line of products. The I3cT includes a full selection of sleeves to ensure a perfect fit and a carrying case. Shure makes audio equipment - microphones, earphones, mixers, etc. that are used by professional musicians the world over. Shure knows sound. If your sound is important to you, you want earphones engineered with the same kind of technology that your favorite divas and bands use to be sure they can hear themselves during a performance. That's Shure's "Sound Isolating" technology. Rather than introducing external elements to block out ambient sound (as noise cancelling earphones do), the Shure system creates a sealed environment that keeps noise out, without covering it up by injecting noise-cancelling artifacts that can interfere with your calls or your music. You'll hear details you never heard before.
