It is stated briefly on the manual that the Ozone Onda 3HX is compatible with the Mac. You just need to configure a few things in the System Preferences.
First, just connect the headset as if you were connecting the headset to the PC – Onda 3HX Quick Start Guide.
Open System Preferences and then on the hardware section choose Sound

If your iPod previously used on a Windows computer isn’t syncing with a Mac, you need to check the Disk Format on your iPod.

To change the Disk Format on your iPod, click on the button Restore
