Etymotic ER38-14FE 標準黑色泡棉耳塞

These worked perfectly as replacements for my ER•6i earbuds, and the foam is dense enough to block out office noise without feeling stiff in my ear.

Finally, foam tips that don’t compress my ear canal too much—the memory foam holds its shape after a few hours of use. They’ve cut down the ambient noise in my commute perfectly.

My old pair's foam had gone flat and hard, so I ordered these for my ER•6is and they seal like brand new again. The fit is snug but comfortable, and the noise isolation is noticeably better than the worn ones. These will definitely last me another few years of daily use.
