I’ve got the closed back ones. Fair warning, the cable and adapter situation is frustrating. The 1/4 adapter broke on my pair. I’ve got at least 5 different adapters from different name brands, none of them would stay on the end of the Neumann cables. For some reason, the snap on ones I had would not stay on, who knows why that is as they work on every other pair of headphones I have. The threads on the Neumann cables will not thread on any of the thread on adapters I have.

Neumann, in essence, has managed to make something as common as an 1/8 cable end, completely proprietary for their system. I had Sweetwater contact Neumann about buying their adapter, and Neumann said they don’t sell the adapter separately. I would have to buy a WHOLE new cable from them with the adapter on it (which is $40). So now, I have two different cables that came from Neumann with the headphones that are worthless because a simple snap on adapter will not stay on. Their response is to buy a third cable so I can have an adapter. Pretty dumb…

I reached out to Neumann a few different ways on social media and got not response. So fair warning, DON’T loose or break the Neumann 1/4 adapter as it’s basically worth a lot more than it’s weight in gold . That drama aside, my other complaint is that the Neumann cables are hellishly microphonic when it bumps up against a mic stand or anything else. If the cable so much as lightly taps something, you feel it in your skull. I would highly recommend going third party and grabbing one of these, it’s much better and works with normal human made 1/4 adapters (and not microphonics):

As for the cable being on the right side, just turn them around when you’re tracking? That’s what I do, because it annoys me when I have to play guitar.
