If I may add a few things… I’ve gone through most of Sennheiser’s lineup (as I should, so that I could more easily help people with questions like yours in my role as Community Manager for Sennheiser). For an open-backed headphone, the sub-bass extension on the HD 58X Jubilee and HD 560S is quite rare. If that’s a non-negotiable criteria point for you, then yeah you will be hard pressed finding “better” sub bass in other open headphones, including outside of Sennheiser. Maybe some semi-open headphones, closed headphones, or in-ears (I quite enjoy the IE 300).
With that said, so many things in audio are trade-offs. Part of what makes the sub bass extension so good in the HD 58X Jubilee and HD 560S is the new material used in the driver membrane, but if you used that same membrane in an HD 800S design, the resulting headphone would lose out in other areas. Few songs make use of or have much information in the lowest audible frequency ranges… typically it’s synthetic instruments or pipe organs that can produce subbass frequencies at the same dB level as more typical bass or mid range performing instruments. Who knows… you might enjoy other headphones with most songs even if they had less presence than the HD 58X Jubilee with the Dark Knight soundtrack?
Personally, I don’t reach for the HD 58X Jubilee anymore for a use case, between the use cases for the HD 560S, HD 660S, and IE 300. Part of that is personal preference of course! The HD 560S is in a similar price class as the HD 58X Jubilee, and it trades some of the bass emphasis fun for a more linear, studio monitor balance of tones, but that change also decreases masking and makes small details easier to distinguish. I also find the angled drivers help with the presentation of imaging and sense of depth… I don’t find it incapable of intimacy and ASMR spine-tickling whispers in my ear (I don’t feel like the mids are recessed or performers are artificially pressed away from me, it’s just better able to give a sense of the farthest reaches of the stage and still have them feel far), but some people feel that soundstage depth comes on the opposite side of the spectrum as an intimate sound where the stage is compressed.
However, the HD 58X Jubilee is indeed a fine headphone with strong price to performance. That’s a praise I’ve seen heaped on that headphone again and again! People also say the price to performance on the HD 6xx, and even the HD 600, are all very good, but not everyone likes the intentionally lowered highs of the HD 650/6XX (these highs are higher than female vocals… think more forgiving cymbal crashes). The sound from the HD 600 and 650/6XX is more refined and clearer sounding than the HD 58X Jubilee, and the 600 series do reveal more of their former-flagship level performance when connected to higher end audio chains, but some people choose the Jubilee anyway just by preference for the tuning and ease of amping.
Unfortunately, I’ve never heard a headphone sound exactly like I was expecting based on a frequency response chart. They’re a handy place to start and can vaguely help to cross out some extreme tunings, but unfortunately they leave a lot of the experience out compared to listening and observing holistically.
There’s really no “wrong” answer here, and it all comes down to your budget, tonal preferences, and minimum performance expectations. I’m glad you seem to be enjoying your Jubilees!
