Try some kz star tips. 3 pair for 79 cents on aliexpress. Super cheap but work really well. (Do not come off) Symbios defoamed are good too.

I rolled with Dekoni foam tips, Fiio memory foam tips, balanced silicone tips and bass silicone tips. The Fiio memory foam tips that came with my Fiio FH5 sounded the best to me. They maintained the low end and smoothed out the peaks in the treble without losing detail. Given, I prefer a warm sound signature due to treble sensitivity.
Dekoni foam tips reduce low end and elevate the highs slightly giving a more neutral sound signature. Silicone tips produce a nice detailed sound with a bit of brightness and extended bass (slight v-shape).
Thanks guys! I'll have a look there
