Lightspeed Zulu.... way quieter, better clarity, can plug in your music or bluetooth it if you prefer, automatically mutes the music if ATC or someone else in the plane talks. Used in props and the CRJ. Can't even hear the fans in the CRJ with these on. I like the Bose, they are comfy, but the Zulu's seal around the ears is much quieter and more comfy. Thats just my 2 cents.

Also if $150 cheaper than the Bose, and they will let your trade your old lightspeeds up (uo to $500) towards the Zulu's.
