Concerning the in-ear phones, I own the Etymotic ER-4P and the ER-4S. Both models are highly regarded by the folks at Headroom.com. However, I recently bought another in-ear phone--the Shure E2c. They are now my favorites.
1. They seem more durable than the Etymotics
2. Everytime you move your head or move the cable, the Etymotics rumble; the Shures are quiet.
3. The Shures cost only $100 new.
4. The Shures are less colored as measured by an electrical engineer named Siegfried Linkwitz.
Here is a quote from his website:
"There are definite differences between the three earphones that I tested, though not so much in their sound, if you equalize two of them. The ER-4S definitely need equalization, otherwise their sound is quite colored, which is easy to spot on most recordings. The MDR-EX71SL could almost be used without equalization since the canal resonance shows only on certain program material. This might be acceptable for general listening but not for use as a sound reference. The E2 meets my sonic requirements right out of the box. These are the sturdiest phones of the three in all aspects. Vibration transfer from the cable is low, on par with the Sony and far better than the Etymotic. Sound isolation against ambient noise is not quite as high as for the ER-4S, but higher than with the EX71SL. The $100 price tag of the E2 falls between the EX71SL at $50 and the ER-4S at $270.
I want to emphasize that anyone who makes critical evaluations of loudspeakers needs to know the quality of his source material. Any one of the three earphones that I investigated can become a useful reference transducer."

One drawback to the Shures for my ear canals is that the Shures do not fit inside the canals as well. So I take the silicone inserts from the Etymotics and put them on the Shures. Voila! The fit is great FOR MY EAR ANATOMY. YMMV.
But you can buy the inserts directly from Etymotic for $14 for 5 pairs. Etymotic calls them Flanged Eartips.
Good luck.
