Headset volume requires more adjustability

There should be a way to adjust the volume without spending more money on another headset or bluetooth earphones

Sorry to hear about that, have ago a this:

To connect a wired headset

Turn down the headset volume by rotating the volume control all the way to the left.

Insert the headset plug into the expansion port on your game controller.

Put on your headset and adjust the microphone.

To adjust the volume: Rotate the volume-control knob.

To mute: Switch the microphone button on the headset cable.

Hello Terrance,

Thanks for coming to the forums with your question. You will have to adjust the headset volume in the audio settings move it to the right for more volume in the headset. Also make sure your party chat output in volume settings under Display and sound is
set to headset.

Thanks,

Brad

Sorry to hear it. I'd recommend checking the headset settings to make sure the sound settings are adjusted properly. If there is no option for balance/volume on the headset then use the console volume settings to adjust your settings.

i believe if you had the stereo headset adapter you could adjust the chat volume to a more suitable level than the game. you may want to turn down the master volume in BF4 options menu
