Zulu's
Had a pair of Zulu's since Nov. 07 and about 100 hours use since then.
So far so good.
The build quality looks very good, and perhaps better than any other on the market.
They have a lot of gadgetry in them, mic gain knob on the mic, 6 micro switches in the battery pack for various functions, and 8 other selectors on the outside of the battery pack. So you will need to look after them if you want to avoid problems down the track.
The head band and ear muffs are of the same material as Bose use and being a very light leather/ette? will need replacing in a year or so I'm told, about $50.00 worth.
Had a glitch for the first time this morning with the Bluetooth turning itself off after about 5 mins, the supplied plug in lead bypassed the problem. The problem may well be with my phone (LG TU550) which also went a bit cranky on that flight.
I still continue to be impressed with the sound quality for listening to tunes.
