Query: Not mac compatible ...

Do not be fooled by the mac compatibility logo on the box. This product is falsely labeled! I needed a headset to use Skype on my G4 powerbook and bought this product because it had a mac logo on the box. That would normally mean it is mac compatible. However, this headset is not compatible with macs. I did some brief research and realized this product does not work because my mac only has a "line in" plug (as with most macs). In order to use this product, you must purchase a separate USB converter (not included).If you are looking for a headset to use with your mac, make sure to buy one with a USB plug. I bought the Plantronics Audio 85 with USB for Apple on Amazon and it works just fine.
