If you want punchy and cleaner sound with forward vocals - you may want to look towards the HD600. It is warm enough for me with a tube amp - especially in the mids, which is where either headphone shines.Been a slow morning at work so I've been comparing my Aeoluses and 58Xs from an iFi Micro BL and despite the somewhat wonky and maybe veiled? sound and worse technical performance of the 58X (with Yaxi pads, I might add), the vocals and lower end have such a thick meatiness to them that they just make the Aeolus sound thin in comparison which is honestly making me wonder where to go next. I've tried EQ'ing the Aeolus a bit but can't seem to be able to achieve the same results.
If I specifically like the punchy bass and thick and warm mids and especially the thick and super present and forward vocals of the 58X, would the HD650 be a solid upgrade if I wanted what the 58X gives me, but just a bit... cleaner, I suppose? I know the 58X has the most bass of the lot, but I'm not opposed to EQ'ing some more lower end in.
The HD650 is less punchy, but still more bassy and more warmth, and more... idk "euphoric" sounding? They are very similar, but, the vocals on the 650 are certainly more buried "in the mix" when compared to the HD600 - which really bring forward vocals (in a good way). Out of all of the series, the HD600 is the most punchy of them and the cleanest sounding...
I honestly prefer both the HD600 or 650 over the 58x - so, you can not go wrong with either if you have the proper amplification. (...Not that the 58x is bad at all, it is still my go-to for EQing into bass cannons for electronic music)
