Try the Lightspeed Zulu. Much like the Bose but is $200 CDN cheaper and has Bluetooth, iPod adapter, and slide volume controls. The ANR is the same as the Bose, and wheh it runs out of battery juice (~35-40 flying hrs), can get a tad noisy. Only draw back is mic changability if you are flying different helicopter types (A++, C++). The mic also doesn't swivel around like the DC, therefore there is a right and left ear only fitting.
