Some weeks ago someone (or maybe more than one) endorsed the AZLA SednaEarfit XELASTEC eartips. I recently got the ML/M/MS set and I'm really liking them, ML in the right ear and MS in the left. Also with my 7Hz Timeless.
At first, I was annoyed that the lower end was reduced. But then it occurred to me that it wasn't (really) because of the Azla, but because I had been using the bass tips from my Fiio FH5.
I tried some other filter combos to get back some thump. I had been using gray lower and green upper and felt like that was my long term option. Now I'm black lower and gold upper and I think that combo will do it.
Great tips, try them if you are are tip rolling.
