Is it possible to mod ER4P memory foam tip into an earplug???

How about you get some earplugs?

The cheap ones are made of foam.

You can't

Custom ear plugs don't even go that low

You could, get a Noise canceling IEM, wear them and place a Bose over your head and use both at the same time.

Or are there any cheap foam earplugs as good as these ER4P tips that I can buy at a store? What kind of stores can I expect to find them???

 

Thanks in advance!

Ety makes purpose-built ear plugs.  Check them out on the Etymotic site.  Also, you can buy Howard Leight Hearing Protection plugs  --  I have used these at the track and they work well.  Same concept as foamies, but denser and better than any home-brewed concoction you are likely to come up with. Again, check on line.

IEM's are really isolating, as long as they aren't ported or vented

If she needs ear plugs, for a job or something, send her to a Audiologist. Around $60 gets you a custom made for what you want.

Works about the same. Just make sure that you know the deep insert isn't for everyone. I enjoy it, but a lot of people DO NOT

Go down to the local drugstore and pick up a package of Flent foam earplugs. I think they have around 30 dB isolation, and are dirt cheap. Some models have as much as 36 dB, IIRC, but 30 dB is easily found. A pack of ten will set you back around $3-$4.

Most drugstores will have an isle full of earplugs.

ER4p's might not be the best idea for blocking out sound while sleeping.  First of all, etymotic tips, especially the triple flanges, are not considered comfortable at all.  They might not bother you, but if you keep them in your ears for 8 hours I can almost guarantee that your ears will start hurting.  ER foam tips are also nothing special, in fact I think comply ones are more comfortable and isolate just as well.  Many people also don't like sleeping with a long cord around their head, which headphones have.

If you didn't know, ER actually makes earplugs.

they're basically just plastic nozzles that you can stick any sort of tips on.  Something like that might work better.
