Thanks. Haven't heard 407/507. Interesting how we're passing time waiting for Shure. I think the message here is that bass and electrostatic are not adversarial terms in earphones. Like any headphone, it will be a unit to unit evaluation.
In this design, since the amp is part of the package, Shure got to chose the bass character they wanted, It's very easy to to give a rising bass curve below 100hz in the analog domain with only a few passive bits before the amp stage. If you want more bass, they do offer EQ as well.
It just that there doesn't seem to be any consensus on what is a correct low bass quantity on IEMs. I'm of the mind that some rising of slope below 100hz sounds most like free air listening due to crosschannel bass bleed and reinforcement in free air acoustics but how much is always a question and what happens when all the bass is in only one channel of a source. It would then appear to be too high so to get it about right will always be an approximation. There is no absolute right or wrong on what a bass slope should look like and it may be better to err slightly on the low side (which for me would still be a subtle rise) for a monitor type device.
