Etymotic ER38-14F 標準黑色泡棉耳塞套

Finally getting these foam eartips was worth the wait — they fit my earbuds securely and block out noise much better than the silicone ones. The black foam is soft but firm enough to stay in place during walks.

I was a little nervous about pre-ordering with no ETA, but these foam eartips create a much deeper seal in my hf5s than the silicone ones ever did, making the bass noticeably punchier.

These foam tips fit my ER4s perfectly and the seal is rock solid, blocking out way more noise than the silicone ones I was using. Even with the pre-order wait, I'd say it was worth it for the comfort alone.
