In this case, not really. Dynamic driver earbuds have been around for a while. None of them ever have been any good. Ever. I don't expect any of the newer ones will change that. Though because earphones are a hot new fashion category, so they will be more expensive than past ones of similar or better performance.
IEM's really only became a thing when Etymotic Research started adapting balanced-armature drivers from hearing aids for earphones. Then others (Shure, Ultimate Ears, Apple, etc.) followed suit, some adding multiple drivers for greater SPL. The gulf between the BA units and the mere dynamic driver units is little narrow now than it was when the Ety ER-4 first came out. If the dynamics have gotten a smidge better - they have, but in the main the best of them are basically on the level of the decade plus old Senn MX500 - the balanced armature ones have improved at if anything a quicker pace.
Keep in mind also that a very large dynamic driver either means extreme discomfort due to the large housing pressing against one's ear-parts, or a big ugly blob sitting outside the ear and a long tube that will have its own resonant signature to feed the sound into the ear canal.
Maybe RDL can make it work decently well, but we're still talking about a kludge here compared to starting from current best practices.
