...because real Flares sounds good only with foams or perhaps custom tips (still waiting on mine). People read your posts and might pointlessly spend money on tips like SpinFits or else - I've tried 15 different silicon tips and it makes no different, all sounds terrible compared to foams.
When I tried Flare R2A the foam did not sound as good for me as soft silicone ones. That could be because I have a rather small ear canal that makes even foam earplugs a little tricky to insert. So it may be that the overhang on the Complys and inAirs was overhanging and being pushed into the path of the driver by my ear canal. In any case, when I used HiFiman small double-flange they sounded great and not harsh.
