I don't have the Momentum in-ears so I can't comment on those. I do however, have Momentum OVER ear (full size headphones), and I can say that it's a relatively 'consumer-oriented' v-shaped sound signature. I've heard the Momentum ON-ears and they are tuned in much the same way. It's logical to assume that Sennheiser would tune the Momentum in-ears with a sound signature consistent with the rest of the Momentum line.
I have the SoundMAGIC e10, and they are really nice. They are a little more bass-centric, but not overdone in a boomy way. Instead of the e10, you may want to consider the e30. While I do not own the e30, they are purported to be more neutral. You can read more about both of them in this review thread:

If you need the control remote, look at the models that end in c (ie e10c, e30c, etc). The 'c' adds the in-line remote.
You pretty much can't go wrong with anything SoundMAGIC makes. I have their HP150 & HP200 full-size headphones as well, and they are stellar.
