But I'm not sure how good it'll sound compared to the normal plasic gels.
What's the big difference (aside from price) to jump to the E5C?
Ears do differ. I just used the E2c's for nearly 20 hours again transatlantic/transcontinent. No problem witht the foam tips.
I tried the E5c's for a week and returned them to Shure. I was hard pressed to find much improvement in quality at all. Might just be my ears. Factoring that into the noisy ambience of an airplane, I thought it not worth the price difference. If you buy directly from Shure, they have - or at least did have - a no questions return policy.
