Sennheiser HD 599 I had few years and I don't think I will be changing them unless one of my two Cats chewed on the cheap cable thou easy to replace with same cheap cable as cable is phone plug-in.

I did this REW frequency test 2019 with a simple foam and Behringer ECM8000 placed over the left/right of the headphones.

I used a smoothing not sure which? I have redone the test again tonight with rant video once loaded up I post the rant as I like a good rant about audio.

I've triggered off my tinituits in my right ear, after the test with a final sine wave tone test up 16.000KHz so I'm not all handicapped on my hearing, no thanks to unversal pictures battlestar galactica in SENSURROUND around 1979. ... Oh it has faded down on right side now between typing (sigh). I better drink some orange juice to more. ....(sigh) it has faded back up again. I get the video gonna take over hour so shutting the THX cinema room down going to bed.

So here is the new frequency sweep no smoothing and looks satisfactory enough. These same headphones used on the Apollo moon landings, worked for them so shouldn't give me any trouble. :D

I should have expended the frequency sweep to 24.000KHz, I guess my demantra is getting worse. I get dizzy head spells when laying down on bed, when laying down.
I do the test a bit more better later in the day but (in bed at present) my tinnitus is hissing and so I may do the Next test when I have the time for myself. :( I don't know why I tested at low frequency sweep, very little pressure of the tone I could notice with sine wave test at 17Hz and don't want to damage the headphones. They may produce that harmonic distortion and I shall conduct my test for my own findings whether or not they do?

Just curious which one you were talking about.
The 559 or (black) 599


EDIT: makes sense now.

When I have two cats running around to look after, It can be complicated work on such a simple thing. So there was some continuity error.

It's amazing what slight adjustments justify a whole new headphone release.

HD559... the lack of silver trimming on the headband gave it away.... and the box.
I assume he always thought he had the HD599 ?
