Can I use the AO Safety protective goggles with other eyewear?
Some of the safety glasses are designed to fit over other eyewear, while others aren't. The AOS-247TGV0120 is designed to be able to be used with glasses while the AOS-114570000020 is not.
How effective are these earplugs at blocking noise?
These earbuds have around 30 dB NRR (Noise Reduction Rating) which means they'll lower outside noise by 11-13 dB. This is enough to put most power tools and equipment into an acceptable range for exposure.
