I bought these in January this year and didn't end up using them much. I thought I was going to have to be working in a noisy environment (where they would have been great) but that didn't happen. So they've only been rarely used since then so are in excellent condition.

Comes in the original case, with manual and all the little bits and pieces, airline adaptor etc. No battery with it though.

I chose them originally as they were recommended by Consumer as good value for money (verses the $$$ Bose versions).

Sounds best when in noise canceling mode (can sound a bit thin when not) but I wouldn't call them audiophile quality (but then no noise canceling headphone is). Would be brilliant on a plane.
