Summary: It really is compatible with the iphone...Yippee!! Sound is clear. It even has enough bass, which is more than I can say for my other pair of Shure E3s. My only beef would be the lack of a clip for the mic. I find it dangles kind of far, past my shoulder, and I'm often concerned about the other party not hearing me. But then again, I've never had a complaint from the other end either. Anyway, I now carry a mini butterfly clamp with me so I can clip the mic by my collar.
Summary: Since receiving my earbuds yesterday, I have been testing the Shure I2c-mp's against Sony MDR-EX51's and Icemat's (Steelseries) Siberia Full-size USB Headset (w/full coverage ear cups). So far I have used the Shure I2c-mp's with my Blackberry Pearl and two laptop computers with different audio cards. No problem connecting to a standard 3.5mm stereo outlet.
I bought my Sony's several years ago for $39, and the Shure's this week for the same price.
Summary: I've had Shure headphone in the past and I decided to give these a try to work with my G3 iPhone. The sound quality is only a little better than the standard apple headphone. The rubber earpieces are hard and eventually hurts after having it in for too long. They used to come with the foam earpieces on the older models. I suggest buying those if you have smaller ears like myself. They fit better and are more comfortable.
Summary: I'm extremely happy with the audio quality on this headset, as well as the isolation. The headphones have a clear high end and a tight low end without being overly bright. Overall they just sound natural. I regularly walk on noisy NYC streets, and ride in subways, and they block out most to all of the sound. Also having the mic on the headset is great for talking on the phone, and it sounds better than the iPhone mic.
On to my qualms about this product.
Summary: The best thing about these headphones is that you can hear most of the sounds that each song you listen to is made up of. The bad things are that the headphones hurt the ear canal and there is virtually no bass. Even after I made a tight fit between my ears and the headphones, there was no bass to speak of. People who don't like bass, these are the headphones for you; they are clear and have a microphone.
Summary: I've had this headphones for a few weeks, and they work very well, they deliver very good quality on the music (although I am no expert).
The only minor drawback is the carrying case, which is too big to carry on my pocket, and that makes me not take them around on the bus commute, which is one of the things I wanted them for.
Summary: Soud quality of mic and earphones is excellent and outside sound isolation is great. Nice carrying case and comes with a wide selection of sizes and types of plugs for any ear. Although they are very sturdy, they are a bit bulky and the volume control (which is very sensitive) and mute button are very near the phone plug. Better design would probably be to merge the microphone with the volume/mute control and put it at the join of the two earphone wires.
Summary: Very nice set of earphones, and some of the most comfortable ones I've worn. I've used the black flexible rubber set of earphones over a nearly 10-hour airplane flight from Rhode Island to California, and they were great at keeping out the airplane noise and the screams of toddlers.
The volume controls are bulky, however, and the wires are rather thick.
Summary: The Shure line of earbuds and headphones is top quality. I own several pairs of Shure earbuds, and I have always been very happy with the range of frequencies and crispness of the sound produced. One criticism of Shure buds that I have seen points to the apparent lack of strong bass, but with the i2cT, the earpiece is large and bass conductivity is strong if you wear the buds properly (you have to get them snugly into your ear).
