And because of that they will sound different (better or worse)
Definitely agree boss.
The SMABAT M2S Pro and the M0 are a really innovative idea for earbud junkies like us. I know you and some other esteemed folks here are really adept at soldering and doing DIY stuff. But for most of the rest of us and for newcomers who don't have soldering or DIY knowledge, the modular design is really helpful, since it is just a click-like design to combine the different dampers and drivers in various permutations to get the desired sound signature.
I think if SMABAT releases various shell housing designs of different price ranges, but still utilize this modular damper/driver design, and maybe they can add exotic stuff like beryllium drivers or wood shells, they can really dominate the earbud market.
