I love detailed IEMs that still have nice Bass presence. I guess a nice W tuning would be a good description if you check my signature.The phones you listed all are competent phones, all having different approaches to sound. Volts are slightly more mid centeric in how it is tuned with the bass and treble accenting its focus with a large wide stage. The FH9 is more energetic in approach to its tuning a large spacious broad v shaped tuning. I would say detail wise these sets are comparable but their presentations are more different than similar. Volts have exquisite rich tonal qualities that makes them unique among tribrids. If you value vocals and or acoustical richness and a fuller note weight Volts stand tall as one of the richest full bodied sounds around. The FH9 is also got a large big sound but it is more based on its bass presence with ample treble with very good detailed presentation. Its got excellent technicalities and detail but is more based on a fun and energetic signature with a foundation for its sound based more on bass and its treble emphasis.
SA6 and H50 I mentioned before and I do consider the SA6 a higher tier of earphone above the H50 but for sheer enjoyment thats where the H50 gets more closer. SA6 looses out to the volt and FH9 in both stage and scope of sound. But the SA6 has its own tuning that is more focused on harmon neutrality vs the the more colored earphones on your list. If you want a highly detailed monitor in the price range of the H50. I would look into the Tansio Mirai Sands.
If you want something that is more musical in approach that is where something like the H50 and even more so the Volts and I would put the FH9 in that mix as well comes into play. The SA6 is the most neutral out of all these earphones but has some very good imaging and detail going for it.
All the phones mentioned here has their merits and it will be more of a matter of what your looking for in a monitor more so than what is more detailed vs another as they are completely different sounding and competent in their own ways.
Would you say the FH9 is overpriced compared to the Sands? From your review of the Sands, it seems like a detail monster at a very good price.
