The Logitech G933 is a wireless headset, it needs the wireless USB adapter to connect, this adapter is basically nothing more than a sound card. However, you cannot use the headset with the AE-5 for wireless communication, the AE-5 cannot act as a wireless receiver/transmitter. If you buy the AE-5 then only if you want to use your G933 wired (but you still need cable adapters). So it doesn't really make sense to buy this sound card unless you switch to a wired headset.
