When you go further down on the same page and touch on the “Details” section of the item it says that the 2.5mm gold cable is balanced. Also TRS and TRRS are the difference between a single ring post plug and a double ring post plug on your headphone cord (see attached photos). It stands for TIP-RING-RING- SLEEVE. The double ring post plug became popular in 2006 and is mainly used on stereo headphone cords that also have with a built in microphone. It allows you to hear things in stereo while also being able to communicate. The headphones you received with your smartphone is what’s considered to be a 3.5mm TRRS Cord. A 2.5mm TRRS is exactly the same except it has a thinner tip on the plug.
Hope this helps, happy listening.

Are the pins on these 0.78mm or 0.75mm? I have a QKZ MK4 that has 0.75mm and I cannot find a replacement cable for it since all the options available to me are 0.78mm...
I'll answer it myself after all the testing lol.
0.75mm and 0.78mm are so tiny of a difference that literally any 0.78mm aftermarket cable can be used for QKZ VK4.
