I use the Zulu Lightspeed Mk1 for flying the R44 and Jetranger and have found it to be great in most areas. Tried using a Bose headset flying a R44 and found it to be similar for noise reduction but the clamp force appeared to be a little greater with smaller cups than the Zulus. Both headsets are light and comfortable however I had to purchase a cotton cup cover for the Zulus as they promote a fair bit of sweating from the ear area especially out here in Africa. I feel that you get plenty warning of impending battery failure with a flashing LED light on the volume control box however with the ANR switched off the noise becomes horrible and for long legs it would be torture. Your choice of glasses/sunglasses also makes a big difference to effectiveness. I use the serengeti brand with very narrow arms which afford the best seal between ear and cup. All in all I rate the Zulus highly however the Bose are also not bad just for the extra money it didn't appear worth it to me.
