I own both the FLC8D and N, and previously owned the S model.
It's clear the D and N have roughly the same tuning as the S - which is fantastic for me, since I adore it - but with improved components and ear-pressure relief, I think they have noticeably improved resolution over the S.
The D sacrifices the ability to tune the bass for a mostly closed-in design (aside from the pressure relief vents on the inside of the shell). So it's no surprise that it sounds more closed in than the N; no so much that it has much less soundstage width, but rather there are perceptual boundaries to it, while the N is closer to creating the 'headphone-less' effect. For some, this lack of ability to tune will mean the D's default tuning is too bass heavy; it's similar to red inner, black/gray outer on the N or S models. The N's default tuning with black outer and gray inner is just slightly more open and natural sounding, and of course you can reduce it at will.
The benefits are that the D is simpler to use, isolates better, and is more protected from the elements and sweat. Having no outer vent means no whistling created by fast moving air, whether that's due to running or cycling, or just strong wind.
I think both the D and N models offer beautiful sound, and it's great to have these options for different use cases.
