Hmm, common people:
- Etys come with 90 days warranty, no money back warranty, a flimsy thin chord, and a crappy fragile connection to the headphone.
- Shures come with a 2 year warranty, 30 day money back, post warranty cheap replacement ($50 for replacement after warranty expires), thick durable chord, rock solid construction.
Sound wise, maybe the etys have a more pleasant treble. Shures have a clearer, more emphasized mid and an incompareable bass. Comparing the E3's to the ER6's is a joke!
The shures over emphasize the mids to allow people to hear clear sound in a loud setting like a stage, a noisy office, a train. They have slightly rolled off treble for that very same reason. The treble can however be brought back in full with minor equalization to sound more "pleasant". But then again, if you're going to compare the E3c's to a cheaper pair, why not compare to $20 sony earbuds. Hell, those have a more "pleasant" sound -- very strong muddy bass, no mids, overemphasized treble, and none of that annoying detail ofcourse
The Shures can only really be compared to the Ety ER-4 -- look at the charts

So the treble is over emphasized on the ER-4's in parts to bring that openess to the sound, making the shures sound claustrophobic by comparison. But hell, for the durability of the Shures and the far better warranty policy, I'll take the E3c's over the Ety's anyday. I just fire up the great equilizer on the Iops MFP350 player to completely remove the intentionally claustrophobic sound.
