Greetings Traveler! To the best of our admittedly limited knowledge, a PC or mac will only allow connection to one audio output device at a time, so to use more than one Mobius you'd have to go the old-fashioned 20th Century route of 3.5mm AUX from the headphone jack with a headphone splitter. In this case, you'd lose any 5.1/7.1 surround sound, but you'd still have 2-channel speaker emulation and head tracking capabilities.
We have heard rumors about techniques and devices that allow for simultaneous connection of more than one device over USB and/or Bluetooth, but we haven't successfully tested them and cannot offer support for them at this time.
Note: We also cannot provide support for connection to multiple dimensions simultaneously, but we’d love to hear about it if you’ve found a way to do so!
If you have any additional questions regarding your Mobius, please peruse the other support articles located in our Help Center. If you cannot find the answer you seek there, please feel free to contact us directly at email@example.com.
