Learn the correct way to replace yellow foam eartips on Etymotic ER series earphones, including tips to avoid damaging the nozzle and ensure a secure fit.
Quick answer
To replace yellow foam eartips on Etymotic ER series earphones, gently roll the new tip onto the nozzle until it seats fully, then check for a snug seal. Avoid over-stretching or twisting the foam.
Why foam eartips need careful handling
Yellow foam eartips compress to fit the ear canal and expand for a secure seal. Unlike silicone tips, they can tear if forced onto the nozzle at an angle or if the nozzle is not clean. Taking a few extra seconds during installation prevents premature wear and ensures consistent sound isolation.
How to replace yellow foam eartips on ER series earphones
- Remove the old eartip: Pinch the base of the old foam eartip and gently pull it straight off the nozzle. If it resists, roll it slightly while pulling. Do not use tools that could scratch the nozzle. Inspect the nozzle for debris or adhesive residue before installing the new tip.
- Prepare the new foam eartip: Hold the new yellow foam eartip between your thumb and forefinger. Roll it gently to compress the foam evenly. This makes it easier to slide onto the nozzle without tearing. Do not squeeze too hard—over-compressing can deform the foam and reduce the seal.
- Install the new eartip: Align the foam eartip with the nozzle and push it straight on until the base of the tip is flush with the end of the nozzle. Release your grip and let the foam expand fully. If the eartip feels loose after expansion, remove it and try a fresh one—foam that has been stretched too far will not seal properly.
- Check the fit and seal: Insert the earphone into your ear and gently tug on the cable. A properly installed foam eartip should stay in place and block external noise. If you hear a leak, repeat the steps with a new tip. Replace both eartips at the same time to maintain balanced sound and consistent isolation.
