Since returning my UM3X I've been trying to find a cheaper alternative that comes even somewhat close to their amazing presentation.
My SoundMAGIC E30s arrived today. My first impression was... meh. It turns out they needed the right tips. For me, the large clear UE tips work perfectly - allowing for a tight seal and better bass response. OK, these things are in no way close to the awesomeness of the UM3X, but they're in the right area. Warm, slightly mid-centric. Not as forward and intimate as the UM3X. Vocals and guitar do well with them. During busy sections of music the separation is not nearly as good as the UM3X. The bottom line, for rock and funk these things are great for <$40. I'm listening to Rush right now and having more fun than my SE535s. Something is seriously wrong here!
Still... I'm looking for the next "cheap-o-UM3X." My Brainwavz M2s should be arriving soon. I'm holding hope.
I got a bit of a UM3X-ish feel from the UE 600 / SuperFi 5. It's too bad UE isn't having more of those $55-65 sales because $100 is way too much. M2 is a good choice as well.. curious as to whether you will like them better than the E30.
