I bought these as an alternative to my high fidelity earplugs, for when I’m trying to work uninterrupted rather than wanting to participate in conversations etc. Upside is that they’re inexpensive enough to buy a few pairs and scatter them where they might be needed rather than carrying them around. But in comparison to my high fidelity earplugs they’re a lot less comfortable - the material is much stiffer (feels more like foam than silicone) and it’s difficult to get a good seal - possibly they’re intended for bigger ear canals. I still use them, but a softer material would be much more comfortable.
