I would really like clarification from MJ about how the stock cable is wired at the headphone cup. There is no mention on the MJ website about the cable; they don't even state the length of the cable. Massdrop only quotes what the manufacturer tells them and doesn't provide any specs about the cable. The only way I learned that the cable may not be wired in the 'normal' manner on the cup end is thru reading reviews and reading here in this discussion. I sent an email to MJ Sunday night asking for clarification and a wiring diagram but have not received a response. I have some aftermarket cables that I either made or purchased and I would like to know if they will work with the MJ2 when I receive it.
I don't understand what MJ was trying to accomplish with their cable that supposedly allows you to plug the cable into the cups without worrying about which plug is left or right and still have the proper channels connected. Someone said the idea is that you can plug the cable in in the dark and not have to worry that the channels are correct and not possibly reversed. But the phones themselves are labeled L and R, so you would have to be able to see the phones before you put them on to get them properly oriented. So it seems to me you would orient the phones and orient the cables that should also be marked L and R and then you can turn out the lights and all is well. It seems to me that MJ was trying to address a 'problem' that really doesn't need to be addressed with their unorthodox cable wiring.
So, if the stock cable is wired as stated in the post below with the L channel as tip/sleeve and the R channel as ring/sleeve, then no aftermarket cable is going to work. You will need to have a cable wired only for the MJ2. It may be possible to open up the cups and rewire the wires from the connector to the drivers to match your cable but I hope that's not the case. Maybe someone here who already has the MJ2 and has only used the stock cable can check the continuity from the cup connectors to the amp plug and tell us how the cable is wired. Would be nice to know this before the phones arrive so I can possibly be prepared with a balanced cable using a 4-pin Neutrik connector on the amp end.
Of course it would be ideal if MJ would respond and clarify this. As I said above, an email to them thru their website asking for clarification4 days ago has not elicited a response.

My conclusion after reading the comment from Sujay Rao ; Using a standard HP cable with 'hot' tips only the Right channel of the MJ2 will produce sound.

The cables are stereo. The cups only have connections to accept the proper channel. I think.

I know nothing about these headphones, but the monoprice M560 has a design that sounds like what might be used here: the cable is a y-cable with identical stereo plugs going to both cups. The left cup only plays the left channel, and the right cup only plays the right channel. So it doesn't matter which plug goes to which cup -- you could do it in the dark.
You could still make a balanced cable for a headphone that is wired this way, but you would have to mark the cable L and R, since there the two channels do not share a common ground.

That's right. You only have to pay attention at the earcups. Left earcup at the left ear and right earcup at the right ear and it's automatic ok !
