There are a lot of different foam ear plugs out there and they are the most common and economical option available for blocking out unwanted noise. You can find them at pretty much any retailer with a drugstore section. If you have small ear canals, you may want to try some that are XS, like these from Ears Secret.
If you don’t like putting things into your ear canals, wax or soft silicone ear plugs can be a good alternative. They can also be found in most drugstore selections.

If you don’t like squishing and molding your ear plugs every time, and if you don’t want to throw them away every time, reusable silicone ear plugs might be for you. These can sometimes be found at drugstores, especially during the summertime because they are commonly used to prevent swimmer’s ear.

If you want to still hold a conversation and protect your ears from excessive background noise, sudden loud sounds, or predictably loud or chaotic environments, you need to check out high fidelity ear plugs. I personally use Vibes, but there’s a lot of other good options out there.
If you are bothered by the amplification of your own voice that is a common downside of most earplugs and are just looking for something that just takes a subtle edge off of everyday sounds, Calmer ear “enhancers” might be a good option for you. They come in a mini size and in a sleep-specific version as well.

And if you really don’t like having anything in your ear canals at all, your best option might be sound protection ear muffs.
