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.

When I first removed the Shure i4cT earphones from their box, I briefly thought I had received the wrong product - the in-line mute button & volume switch is so big, I thought it must be the i4c, with connections for a standard phone and a separate MP3 player. But sure enough, it was the i4cT with a neat little 2.5m plug that fits properly into my Windows Smartphone.
Unfortunately, the 2.5mm plug was the only "neat little" part I could identify. The mostly thick & stiff cable assembly, and the over-sized mute/volume switch (with clip) are so bulky that I was unable to wind & stash it for comfortable usage. Perhaps the engineers at Shure believe the thicker cable elements are necessary to meet their audio standards, but given these are designed to be paired with mobile devices, I'll bet they could find an acceptable alternative wire that is thinner and more flexible.
Now, these earphones do sound really good, no doubt about it. I'll go so far as to say they sound incredible. Had they been less expensive, I might have put up with the poor ergonomics, but there were also a couple of other issues...
When holding a telephone conversation using these earphones, their sound isolation characteristics make it very difficult to hear your own voice when speaking. It's pretty weird - you really have to trust your vocal habits to know that you're speaking at an appropriate volume. The people I spoke with over the phone told me that they could hear me really well (I don't *think* I was yelling :-), so I assume that the microphone is as high-quality as the earphones themselves. Anyway, not hearing yourself clearly in a conversation will take some getting used to if you buy these.
Lastly, the microphone mute button must be held down to keep the mic muted (it's a release-to-talk mechanism), and the volume adjustment dial is a bit too sensitive. Since I can mute my microphone and adjust the volume using my actual phone, I would prefer that Shure remove this bulky component from the product altogether. A small button somewhere on the device for answering or disconnecting a call would be much more useful...
So, I sent these back. If Shure releases a version of these with more attention to ergonomics and the "can't-hear-your-own-voice" issue, I'll cheerfully try them out.
UPDATE: After providing this feedback to Shure's customer support team, I promptly received this info on the "can't-hear-your-own-voice" issue: "That is called sidetone. Sidetone is provided from the phone and due to the sound isolating features of our earphones it makes a lack of sidetone that much more present. You may want to check out the phone preferences and see if it has a sidetone adjustment."...

After lots of research on a headset that would be compatible with my Centro, I went for the Shure set. I am not disappointed. The sound isolation works well, and the bass reflex is impressive. Worth the money!...

The huge white wires and bulky volume/mute control are embarassing to wear in public. But I would if the sound was there...its not!
I have to assume that the set I was sent is faulty. The sound is completly lacking any bass. I tried every set of plugs that were sent with the unit hoping to improve the sound, but no luck.
Further, I receive complaints from people I talk to on the treo about my voice being sounding horrible/echo/tin like/hard understancd ect.
I hope I can find the box to return this....
