I bought some westone 4r which I just got yesterday. My first impression is they have very deep and extended bass. I wanted to know how they compare to the pfe232 and sennheiser ie80 in terms of how deep the bass goes and how good they sound in general.
If you have tried all three or one of them, feel free to leave your impressions.
I also paired my westone 4r with my fiio E11 and on the bass boost settings the bass sounds very powerful almost subwoofer like.
