記憶泡棉耳塞

Took a few tries to get the seal right, but once I did, the noise isolation is fantastic. The memory foam compresses slowly and stays in place even during workouts.

These seal much better than the silicone ones I was using before, and I can actually wear them for hours without my ears aching. The foam is dense enough to stay put but compresses easily to insert.

I've tried a bunch of foam tips over the years and these are the first ones that don't make my ears ache after an hour. The memory foam compresses easily to insert and then expands just right, and the standard size fits my ear canals perfectly.
