One of the few places to still get filters for these great phones. A good deal.

Always easy. Always quick. Still love my ER-4's.

Just what the doctor ordered. Quick and reasonable shipping and price were a bonus!

Finally found a US-Store that ships these filters to Germany with a fair shipping fee. Great. Amazingliy fast and reliable delivery within a week. Well done. thank you. btw. filters are working as designed.

I've had the ER4s for years and have been happy to have found the Earplug Superstore for the needed supplies to keep them in operation. The good prices and quick service are hard to beat.

Quick shipping and delivery to the Netherlands. Will order again if I run out :)
