Where are these made now?

My headjack that connects the headphone to the mic and headset end (green and red) is broken, what do I need to buy to get it replaced? The single port end seems shorter than 3.5mm and is smaller than the port of the mic and headset end. May I know what size to if I necessarily need the exact same one that connects mic and headset or I can just get a single port to single port end? Would I need to completely replace the headset? Also I'm currently residing in Malaysia where ebay and amazon isn't available and I can't seem to find anywhere else that sells it. Is there anyone that can link me to the item that ships to Malaysia?

Hi I am new to the community. Just want to know about these two ear cup dimensions. I am a previous owner of HD58x. Wonder if they share the same ear cup size or maybe HD58x is much bigger? Thanks!

I am looking for recommendations on a good headphone/amp setup for music creation. My son is making music on his pc and has just been using his gaming headphones. I want to get him a better setup. Budget is in the $200 - $400 range total. I personally like Sennheiser but I don't think he has any prefrences. The music is a mix of electronica, dubstep, and video game music. It seems very light on bass to me for dubstep, but hey, to each their own. https://www.youtube.com/watch?v=oJD1_KNeEhI this is one of his videos for reference. Thanks in advance for the help

This is a head set which is one of a kind.
