[..] They're just more enjoyable from the perspective of bass alone. However, I have noticed that vocals just sound completely wrong with these IEMs compared to all my other headphones. I think the treble and midrange just lack a certain amount of refinement. Even though there is more treble presence in these than the EPH-100, I feel that it's not as refined. I'm planning on keeping them though just because they're so darn enjoyable in the bass department. But for listening to anything other than really bassy music, they're just not that good.
Hmmm. I do enjoy some drum 'n bass and dubstep now and then, or things like the Daft Punk - Tron Legacy Reconfigured (remixes of the Tron Legacy OST). I'm guessing these would fit perfectly for music like that, then? Cause if that's the case, it would mean they'd be a nice addition for these bass-heavy electro stuffs. Interested in your opinion on that.
