I have used both. I use active NC IEMs now (Phiaton PS20). I have had Bose headphones in the past. The headphones are better than IEMs but I changed to IEMs when I decided to start traveling light. I don't miss them at all. The Phiatons are very good but I also have Audio Technica and Sony active NC IEMs which are more than satisfactory. I pretty much only use them while watching movies on my phone on transoceanic flights.
