Fostex T50RP planar headphones, as I said in my review: Fostex T50RP MK3 Review (with Shure 840 pads): Hard hitting, cold precision., will give you skull-shaking bass and sub-bass. Too V-shaped (sibilance) for me like that, so I did this simple mod which got rid of the 4khz-to-8khz plateau and made em sound “warmer”.
Sony MH755 are 10$, one dynamic driver, and got smooth sub-bass. Warm sound. Otherwise inoffensive tuning. Great timbre. Be careful, there’s a lot of fake ones. Edit: Recommended seller: Genuine Original Modified Sony MH755 MH750 MMCX Modded Earbuds Earphones DIY | eBay
I still haven’t tried the Truthear x Crinacle Zero, but it’s 2 dynamic drivers, with one driver only for the bass (see the red line below). Very interesting.
