These are by far the best ear tips you can buy. I find all manufactured supplied tips are non compatible with my ears but Comply have been my go to.
They cost around five times what they should but they work and keep my earphones securely in my lugs.
More secure than the standard tips, I've had Comply tips for other ear buds I've owned. Better noise isolation too.
Fell apart after a few weeks of use. Avoid.
The regular tips that came with my Pixel Buds Pro always made them fall out of my ears and the only way to get them to remain securely was to try these "Comply foam tips" I gone for the small size as I have narrow ear canals. I must say, they fit very well and I'm fully able to utilise my Pixel buds Pro to the max. Recommended.
