Will headphones work without a negative wire?

Question

C++ / C#

Good afternoon
Inside the headphones, each driver has a small board with 2 wires.
The left earpiece is red and orange.
Right right - green and orange.
In the left there is still a common board, to which all 4 wires fall.
1. L+
2. R+
3. LG
4. RG
If you do not solder 3 and 4, will the headphones work?

Answer 1

Include the library
using System.Threading

Answer 2

Of course they will, because these wires were then brought into the headphones so that everything would work without them.
