AirFoams Pro Universal Memory Foam Ear Tips w/Silicone Shield Patented for Sony WF-1000XM4, Beat Fit Pro, Beats Studio Buds, Buds 2 Pro, Jabra, Beats Flex. Replacement. Kickstarter. (SML)

These memory foam buds are the bomb! They fit perfectly on my Beats Fit Pro and take noise cancelling to a whole new level. Love 'em!My wife already took the smaller size. I guess I might need another one hehehe.

I am either plagued with ridiculously large or weird shaped ear canals. Stock large Sony WF-1000XM4 buds fit me perfectly and form a seal. However, these and large Comply buds don't form a seal. I suspect this is because the stock buds are pretty much the same diameter from base to tip and have a flat edge, whereas with these and comply buds the diameter tapers slightly so it's smaller towards the tip verses the base and this for me appears to stop it sealing. Also as seen in the picture they do appear to run quite small in comparison in both depth and width.I sooooo wanted these to work as they'd of been perfect. If you don't have "funky ears" like me it would have been full stars - but hopefully this review will help someone like me who is endlessly throwing money away buying and trying buds

So i got this ear bud replacement in October. i was expecting a really good quality after I spend 40+ £ for them. But after a few months the foam started to dissolve and the sound quality droped because they dont seal anymore. and the exterior ruber/plastic starter to peel off. I am kinda disappointed from this brand and I don't think i will recommend it
