May i ask why?

I have the DT990, but it has the same exact cable as the DT770. Anyways, here it is

Sadly the DT770 Pro has two different connectors depending on the year it was made. One has a shorter thread than the other.

To clarify the thread is for the jack adapter.

Yes of course. I wanted to buy a dt770 pro for someone's birthday but I wanted to mod it for the cable to be detachable so I need to order some things as well as the headphones. I wanted to see what the connector looked like since I want to make a cable as well and I was trying to decide if I would use it and if I did I wanted to order a connector that looked alike for asthetics.

Thanks a lot man!

Thank you for telling me.

You can use jack adapter from amazon basics as well, beyerdynamics one is bit costly.

I had custom one pro , my detachment cable got damged and replacement was expensive.

Any 3.5 mm jack works out fine.

Thanks for the suggestion. I just checked there but the shipping is making the price double. Some nice ones I found over here cost form 50 cents to 2 euros. I am a bit worried about the soldering breaking from tension as I didn't find one with a screw. Anyhow I hope it works well.

No problem, hope that helped. Found out when I was trying to buy an adapter.
