Use a magnifying glass and a strong light to visually inspect the USB charge port in the headphones to make sure that all the pins are there and that they are straight and parallel with each other.

Also check for any debris that may be lodged in the port enclosure that may be preventing a good electrical connection. If you see anything in there, do not use a metal pin or probe t try and extract it. Try using a vacuum cleaner and check if it can be sucked out or failing that use a sharpened wooden toothpick to ''gently'' prise it out.

If the USB port seems to be OK try the following:
Plug the USB charge cable into the headphones ''only'', do not connect the other end to anything. Then firmly holding the headphones where the USB port is located, in one hand, using the other hand grab hold of the USB cable plug where it is inserted into the USB port and ''gently, stress gently'', try to move it up and down and side to side to check for any movement in the port connector, indicating that it may be loose from the board. If it seems loose then you may have to check if it is still soldered on to the board correctly etc
If is seems to be OK then further testing with a DMM (digital multimeter) would be required to find out why it is only charging intermittently.
