A:AnswerHi,
Correct. This headset may operate on Bluetooth or via USB/3.5mm. Bluetooth connection is intended for usage with mobile devices, while wired connection is intended for PC/console. You'll also be able to maintain a simultaneous connection to your gaming device (via 3.5mm/USB) and Bluetooth device (typically mobile device) so you may concurrently hear from and communicate to both sources. If you have any additional questions, we'd be happy to assist: help.corsair.com

They all radios of some sort. Transmitting different data. You might be able to find this information in manual or quick guide if not. Email the support or maybe find software that can read what bluetooth it's commicatingn with your computer.
