ba were developed for medical purposes for hearing aid hence their properties in resolution and fast transient response
however for pure listening purposes where timbre naturalness is required dd will always win
p.s. since there are only two main manufacturers - sonion and knowles - the creation of ba earphone is basically like playing lego i even go further and say that one doesn't need special expertise to produce good sounding earphone. however, creating a custom dd is a whole different story and only few manufacturers are able to do this
You have been able to buy Focal drivers for a good long period of time but seldom do you have many producing speakers that sound like the Utopia. The magic is in the tuning, choices, crossovers and enclosure. We have many of people building their own IEM. Go to the DIY forum and note the difficulty they are having to produce comparable products.
Also, just because BA drivers began as part of the medical devices community (which should have been a clue as to the level of engineering in them and a testament to why the SQ that the likes of Etymotic achieved was an option), it shouldn't matter today because they have been in the HiFi game for 20+ years.
Up until recently, there hasn't been a DD IEM that really could compete with the multidriver BA. We will see how long term Vega pan out but up until recently, you had nothing to support the statement of DD superiority...and superiority is still questionable. DD have some characteristics that many might prefer in certain ranges, but it might come down to perfectly tuned hybrids being the best of all. I'm also still curious to to see how the RHA CL1 Ceramic turn out.
