I have been using my Bose QuietComfort 20 for several years. I use them on planes, on trains, in co-working spaces, and even to help me sleep.
I discovered that they are actually quite comfortable to sleep with.
I don’t use them often to sleep. When needed, they worked very well. Noisy neighbors, having to sleep during daytime, or having jet lag. All great use cases.
Here’s today’s idea: Consider sleeping with noise cancelling headphones. (Or consider buying a pair, if you don’t have any yet.)
