In just thinking in terms of potential sales volume. Logically they'd stand to make a lot more money off of a near universal cable with parametric EQ functionality than they would from a single IEM, since it could appeal to people running anything from low end to top tier IEMs (and not exclusively moondrop's own models either).

They could offer just the cable on its own, as well paired with an IEM (or even multiple IEMs across the price range). Looking at it that way it seems like the smart business decision to me, as it would minimise manufacturing costs and maximise potential sales. Whether they go this route remains to be seen.
