Dual-pass tactical headset: divided into the left and right speakers alone sound.
Most people use a single radio configuration, so only the left or right speaker alone out of the sound.
So we purposely made this conversion cable.
Line body an open two, that is, a male and two female.
The female plug can be selected.
One: both are military standard definition output (connected to the original headset or the original definition of the headset)
Two: two are non-military standard definition output (element-based headphones)
Three: two female headers are military standard and non-military standard definition output. (Convenient to connect two sets of headphones to replace the use)
The above military standard refers to the internal wiring method.
