I don't hear audio from the Audio Strap.

Confirm that the Audio Strap cable is fully connected to the accessory USB-C port on the right side of the headset. Then select the Beyond audio device in Windows and SteamVR.

One speaker is quieter than the other.

Check that both speaker arms are positioned the same distance from your ears. Reseat the Audio Strap connection and verify that the left and right balance is centered in Windows audio settings.

The speakers press against my ears or sound too quiet.

Use the side knobs to adjust speaker distance. Move the speakers slightly away for comfort or closer for stronger volume and bass, keeping both sides evenly positioned.
