Maybe I should put more effort into finding out why exactly the left side of my temporary XM4 keeps working its way out of my ear then. I don't think they're known for its thick or short nozzle or so as I can't remember having read that. So it could very well be my left ear canal
And if that's the case I wonder whether a longer, shorter, thinner, or thicker nozzle on my new IEMs could be a solution or that it's down to trying to find maybe grippier tips or so. The problem disappears though when using the included foamies (which are truly exceptionally comfortable for me - I could probably keep them in for 24 hrs) but those suck big time sound-wise. Makes me wonder whether I should invest in new IEMs or in new ears...
