Lightspeed Zulu 
:
These new Zulu's from Lightspeed may well outclass the DC and Bose equivalents.
Seems they've put a lot of effort into building a winning headset.
Fantastic stereo audio with FRC (Front Row Centre) enhancement switch, Bluetooth, + plug in option with 2 leads supplied, auto mute switch for the audio, bass and treble boost, mic gain adjustment, small and sturdy carry case, same ear-cup seals as Bose, light, strong, 5yr warranty and a couple of hundred cheaper than Bose.
Maybe to much gadgetry and switches for longevity though, time will tell.
BUT no user manual or instructions of any kind not even on the box, no information available from their web site, and several emails over two weeks to the service desk and the poor simple lass still couldn't grasp the concept that she needed to email me the user manual. Eventually rang and spoke to a bloke who sent it through in 30 minutes.
