They are also noise isolating, not noise cancellation of course, but they definitely dampen outside sound and would work perfectly as earplugs if you need that level of quiet for sleeping etc

Very comfortable and they make good earplugs to drown out other sound too.

They also work as earplugs and I usually wear them all night which prevents me from waking up from sounds during the night

the most comfortable earbuds l have found for sleeping and plan to order another pair in hopes that it was a fluke with this first pair
