Conclusion: Sooo… the E10 or the E30? It’s simple – just get both. All kidding aside, both are excellent phones for the price. Besides the differences in sound quality I already described above, it’s mostly a matter of fit. While I generally do prefer an over-the-ear form factor like the E30 provide, I guess I’m just unlucky with the way my ears are shaped. It is possible for me to get a fairly decent fit and seal with the E30, but it is not as straightforward as with the E10.
Pros: Clear, natural, dynamic sound quality, Good selection of included silicone tips, Over-the-ear design, Great price/value ratio
Cons: Proper fit and seal might be difficult to achieve for some people’s ear shapes/sizes
