I would recommend the Zulu's over the Bose. I have tried both and the Zulu (in my opinion) is much more comfortable. You also have the bluetooth feature w/ cell phone and MP3 connection built right in, without dropping extra cash on an adapter for the Bose. With that said You really can't go wrong with either. The Zulu and the Bose are far superior to anything else on the market in my opinion. I have also tried the X-11s in flight and was really let down with the sound quality. Other friends that have the X-11s have said that they have a feedback/squelch issue with certain com units.
