Lightspeed Zulu Problem
 

My zulus had some sort of low, clunking noise yesterday. It wasn't very loud but still very annoying. I am sure it was not engine noise - the frequency didn't sound fast enough for anything in the engine. It was more like the noise a steam engine makes when going up a hill - a few beats per second maybe.

It might have been more pronounced in the left ear. Has anyone had any problems like this / know what it might be / how to fix it? In all the posts about these headsets I have never seen any criticism of the Zulus, but I am now wondering if the Bose are better quality (this is the second problem I had - first one the ANR failed mid-flight - couldn't hear a thing. It was to do with the ANR wires coming loose).

Zulu & ANR
 

Man...ANR won't work properly if you "break the seal". Doesn't matter what headset you use.
Give the very helpful guys at the authorised Aus dealer a tingle. Worked for me.
cheers

Thanks guys. Will give your suggestions a go.
