Superb Fit and Sound
Fit: Both the foam and the flange attachments fit comfortably within my ears whereas many other earphones have not. This was a pleasant surprise. Also, a quick note is that you MUST follow the directions on inserting the earphones. This will ensure a tight seal resulting in improved fit, sound dampening, and sound quality.

Sound: The sound is crystal clear and does indeed compensate for the wimpy bass on my ipod. It's not to say that its bass will blow you away, but instead, the bass is extremely accurate and just punchy enough. Also, the higher range and all layers of the music are extremely accurate and well defined. This goes for everything from Mahler to Tool. Every instrument and layer is heard. Definitely will force you to upgrade the quality of your MP3s in your library! Lastly, the dampening is simply amazing. It's great for falling asleep as well as commuting.

Overall, I was between these, and the Bose Tri-port In-ear headphones. If you are serious about the quality of your sound and obtaining a set of "true" in-ear headphones (as the bose more so sit on the inside of your ear instead of going into the ear), then I would definitely recommend the ER6i. This is a deal not to be passed up. Recommended.

So comfortable!
If you are looking for earphones with good sound and excellent comfort, these should be on your short list. I have tried many brands and the Etymotic Research ER6i sound very good (a little light on the bass, however) but they are by far the most comfortable earphones I have ever used. I even forgot they were in my ears which has never happened before. If you're looking for a really good pair of earphones just plug these in and adjust the bass on your equalizer for a great listening experience.

Comfort first -
My need was straightforward: I needed ear speakers of some sort that would not fall off my ears with the slightest movement like earbuds do. An overhead band would be uncomfortable and interfere with lying on a pillow or back in a chair. I was skeptical about how in-the-ear speakers would feel, as my inner ears are very sensitive. These ER6i earphones delighted me with their very soft silicon ear covers. I can wear them for hours and often forget I have them on.
I am not an audiophile, so I can't begin to pass judgment on the audio quality; all I know is that I hear my recorded lectures and talk radio shows completely clearly. I am very pleased I made this purchase.

Fantastic isolation
The hands down best feature of these earphones is the sound isolation. I use them on the train and periodically on the airplane, and the difference is stunning. Not only do they cut down the noise of the train/plane, but also of the other passengers. It means I can concentrate without any distractions.

My husband uses his pair in his office (shared with another person) every day. The main drawback is that he doesn't always hear the phone ring and doesn't hear people come into the office (the door is slightly behind him). I used to think that he keeps the volume too high, but in fact it's not. He just seems to get the tips inserted better into his ears than I do.

I listen to a lot of podcasts, and have noticed that the sound isolation is better with music, where the sound is more constant.

The fit takes a bit of practice, but it's worth it. After about a year and a half, we did buy new ear tips, but that's the only maintenance we've had to do so far.

In summary: we love them!

Excellent for ipod
I use these ear buds everyday at work. I work outdoors with power equipment and the isolation is great. I don't have to run the volume so high.
