Funny, I just posted about this pillow in another thread, but you might find it helpful here too.

I used this with the new Bose QC35 and it worked great due to the structure of the Trtl 'pillow'. It has a cervical support system that you can see in the description, and I was able to position it so that the earcup of the headphones fit right between the two supports when I leaned my head to the side. Not sure if that makes sense, but it worked great for me. The Trtl looks a little odd but is surprisingly comfortable and supportive.

I also find that using earplugs under the headphones really helps block everything out. Pretty sure a baby could be screaming right next to me and I would just snooze away.
