I've used the Bose for two years in Turbo Props for work, king air & beech 1900 and small stuff for fun. Some of the Captains still use old DCs and on empty legs when we switch seats I've used their equipment and honestly don't know why anybody would subject themself to working like that. That being said, the other viable option is lightspeed. Their headsets are bulkier and the sound quality isn't as good, however they are half the price of the bose. The price of the bose is pretty much the only drawback. They do have interest free finance plans however.

That new DC set looks pretty nice, however for only 200 more you could get the bose. Between these two its a no brainer.

Overall I would say the lightspeed is 80 % of the product for half the price. Most lightspeed guys will tell you: "yea....its a pretty good headset" I've yet to talk to a bose guy that doesn't absolutely love the headset.
