Not happy with Sony's earbud case
I bought a pair of Sony wf-1000xm6. I'm happy with the earbuds themselves but my ears have a hard time accepting foam tips. I bought a pair of dual flange silicone tips only to find the earbuds wouldn't seat down to charge with them on. So I sent those back and bought a set of Azla Mithryl single flange silicone tips which I thought looked the same size as the foam tips but I can't charge the earbuds with these either.
It feels like Sony designed their case to fit a smaller proprietary tip. Am I wrong about this? Have I just been unlucky in my silicone choices? Can someone please suggest silicone tips that they know work with the Sony charging case?
