These headphones are super comfortable that I use them for working out or sleeping in the plane. The form factor makes it comfortable so they do not press into your ears when you are sleeping and leaning your heads like other headphones. The sound quality and noise cancelling isn't as great as other headphones, but these are generally solid and reliable all around.
