## Description

Filter Removal Tool and 4 Green replacement Filters for ER4 and HF series earphones by Etymotic Research

Review: Work great - My ER4Ps are over a decade old. Rarely do I need to change filters, but my spouse borrowed my headphones and completely clogged one side, given that there was no sound. It almost seemed like the channel went bad, but the test is removing the old filter and listening for sound. If you still have the case that came with your headphones, you may have the tool already. I see on their website you can buy just the filters, but purchasing here with the tool was more convenient for me. They sound much better, as I had been listening with partial attenuation for some time. Parts look authentic. If you channel is actually bad, you can send your headphones to Etymotic Research for repair. I did that once years ago, and it was something like 50.
Review: Not sure if they are worth it... - The replacement process was easy. My ER3X sound the same as before. I keep my ear canals clean so I suppose the filters weren't needing replacing.

## Questions & Answers

**Q: Can I not just buy the filters separate ? I already have a changing tool.**
A: Checking the Etymotic web site itself today (7/20/16) you can get six filters for $15.  They list the filter removal tool at $1.50.   If you buy just filters they are $2.50 each.  They are $2.87 here if you ignore the tool (which, to be fair, is easily replaced with any small screw.)

**Q: Why not sell filters here alone? 6 filters from etymotic themselves @ $15 costs nearly $8.00 to ship to wa on fedex!!**
A: I concur. Etymotic’s website calculated FedEx shipping costs to my location of ~$44 for a filter order of ~$64, not reasonable. I vote for the 6-pack of filters (without the Changing Tool) to be available here on Amazon, with options for the different colored filters as they have them on their website, if they cannot provide for direct reasonable shipping costs. The shipping department at Etymotic refused to consider my request for an alternate & more reasonable shipping method, nor even explain their position.

**Q: will these work with MC5?**
A: Hello,This listing is for the HF and Micropro series earphones.For your MC series please search for	ER38-46MC Filter Removal Tool with 4 FiltersB009OWPE5QEtymotic Research Customer Service

**Q: Would these damper filters fit an older etymotic headset er-4 micropro? what is the diameter dimension of these filters, & of the er-4 micropro? thx.**
A: While I'm not 100% sure, I do know that I had older filters that I tried using on my newer ear buds and they did not work.

### ⭐⭐⭐⭐⭐ a great tool and replacement filter pack
*by S***N on May 26, 2025*

I've had my etymotic er4-ps for .... probably older than my teenage son in college. I bought them when I had my 3rd gen iPod. Since then I've replaced countless filters and flanges, and only once the cable. These things have traveled the world with me, and while I've moved on mostly to other IEMs, these still come out every now and then, and I'm still blown awa by their sound. This is a great tool to store and remove the filters since I've long ago lost the originals. I like the fact its bigger, and more of a pen size vs my original ones that were smaller and obviously lost throughout the years.
