I have the Lightspeed headset and they are very nice and a lot less money than the DC or the Bose. However, they are freaking HUGE! They get in the way in smaller planes, and (this shouldn't be important) they make you look like a big dork. I have tried the Bose, and sound quality is a little better than the Lightspeed, but is it worth another $550? I say find a place that has them and try them out and see what you like best. BTW, the lightspeeds have an input for the cellphone and MP3 player as well.
