Whizzer ET100
Sound
wide soundstage, clear sound, treble added bit , solid bass response
Fit
not very comfortable with bullet/straight insertion iem, with over ears its decent but not excellent. JVC and Ortofon still the most comfy
Whizzer SS20
Sound
Wider soundstage and more headroom, very clear sound, bass less boomy and brighter treble, mids abit more forward
Fit
Very comfy, almost as comfy as JVC but Ortofon ones is softer and more comfy. This fits all IEM better than ET100
Overall the SS20 white tips is really good but the blue ones ET100 a little picky on which IEM, some may be good and some fit is not that good
hope this helps guys
