I got a pack of basic foam ones (supposedly 33dB reduction), and it meant that my wife and I could keep sleeping in the same bed without snoring getting in the way. Was only about $10 for 50.
And I got a pair of noise reducing Loop earplugs, which means that the one day a week RTO is no longer a sensory nightmare. They're visually subtle enough that my wife couldn't see them when I first tried them on (important if I was going to wear them in meetings), and recessed enough to wear underneath headphones. They're also great for large events (weddings and the like) to extend how long before my social battery gets wiped out. I imagine this is more tied to my autism than the office being particularly noisy though. I can still easily hold conversations with them in, with the only negative being that they kinda reduce spacial perception, so I can't as easily tell where sounds are coming from. These were about $50, though they've got cheaper options, they also come with extra mutes for more reduction, but the baseline is already plenty, so I'd probably recommend against the "Engage 2 Plus".
They're much more subtle than most earplugs, only about 10 dB of reduction, and it's a fairly level reduction across the frequency spectrum. So rather than the normal muffled effect you get from normal earplugs, they sound like you uniformly turned the volume down on everything. In overstimulating environments (noisy HVAC, meetings where the person controlling the dial-in has it too high, coworkers who aren't great at modulating their voices) they're fantastic.
I got the "Engage 2 Plus". Though like I mentioned, they reduce sound by enough on their own that the included removable "Mute" wasn't worth the extra cost over the basic "Engage 2".
And one thing I forgot to mention is that they don't reduce the sounds of your own head. So your own voice sounds the same, and you still get that lip/tongue smacking effect that traditional earplugs have. Neither of those is really an issue, but I may have slightly oversold them with "level reduction across the frequency spectrum".
