Etymotic ER38-14A 小型米色泡棉耳塞

Finally got the right size for my ER4s—these foam tips create a much better seal than the silicone ones I was using before, and I can actually hear the bass now without constantly readjusting.

These fit perfectly on my hf5s and seal out ambient noise better than the silicone tips that came with them. The foam is dense but comfortable enough for a couple hours of listening.

My ears are on the smaller side, so the small size actually stays put during long listening sessions without that stuffed feeling. The foam compresses easily and expands just right for a secure seal with my ety kids.
