Only received them today, but compared to the kz cable, they are much more comfortable to use, and have significantly less hiss.
Set up took me less then 5 minutes with no need to reference the manual, connecting fast, and the feedback the device gave was useful.
They are comfortable to wear, my hair did get caught in the usb-micro slot when i closed it in, but other then that, very comfortable.
The mmcx connections are very tight and have a satisfying click, im a bit scared to try remove it without the help of a thin card or something similar.
I'm using them with tin p1's and they provide enough power to make them sound good.
Overall, they are a very satisfying experience.
