Whichever would closely match or deviate less with your studio monitor speakers as the NDH 30 is modeled to replicate that of Neumann’s monitor sound. I have the Adam A4V monitor and I can easily switch between that and the NDH 30, volume matched they’re close to identical.
Sounds like normal sample variation to me. Channel imbalance is a fault. Try a third pair. I tried four and kept the best two. I’ve done exactly the same with other headphones (840, 1540, 660S for example) All different. No such thing as identical sets of headphones in my experience.
That triggers 10 different kinds of OSD's.....wish I hadn't read that lol
Just making the point that small differences are normal and nothing to worry about.
I could not afford a second and a third pair of ndh30's even I would be eager to test for differences anyway
It is very easy to cause chanel imbalance on purpose with the NDH 30, or different responses between channels. The pads are roomy and all it takes is putting them carelessly on the head, one cup slightly forward and on slightly backwards. The inclined and off centered drivers will then cause this effect. However very soon one learns automatically to center the ears in the pads and all is fine and accurately balanced. If a problem persists, then it is a faulty unit.That is encouraging.....but not what follows. : (
Starting to have some reservations....hhhhhmmm????
For a professional company like Neumann such reports, and there have been a few, is bothersome. : (
Mike, that is scary!....mind you the housing for the driver and wiring is all rather sub par with a bit of foam for damping thrown in for good measure, nothing to write home about, so that could explain some....but still??? : (
Hopefully Amazon can do exchanges and not ask to return for a refund.I could not afford a second and a third pair of ndh30's even I would be eager to test for differences anyway
Could very well be one of the main factors of variations as even in positioning when worn will change the sound (dramatically)Mike, that is scary!....mind you the housing for the driver and wiring is all rather sub par with a bit of foam for damping thrown in for good measure, nothing to write home about, so that could explain some....but still??? : (

And my original HD630VB shown, like NDH20s fair no better, but the drivers are sealed on both so unaffected by the cup.
What I really wanted to say is that there are 100 different things I worry about in my audio chain....I wouldn't dare to go to there thinking my new purchased products has defaults (if they are not obvious ones)....I am not ready to go there....Hopefully Amazon can do exchanges and not ask to return for a refund.
But one would like to believe that with a company like Neumann, consistency would be paramount, I could be mistaken.
There is a reference FR and there are acceptable tolerance/deviation from the reference. Same as the 800 deal.
With how they are with their mics and monitors, yes I agree. Which will also lead us to the price jump on the black version. It better be consistent or it’s unforgivable.
Don't think black will be any more consistent - unit to unit variation cannot be avoided (dynamic cans are already significantly better than planar in terms of unit to unit consistency; and don't get me started on using wood to "augment/enhance" sound). I had 2 copies of 800S and they sounded slightly different from each other with different FR, but both FR curves followed the reference FR printed in the user manual.
Within tolerance of the specs is fine but not when it sounds broken. Maybe it’s just how things are magnified 10-100x in forums such as this
