Yes, you can connect the Arctis Nova 7 to your Sony Bravia X80J (2021) Android TV using the supplied USB 2.4 GHz dongle, but there are a few important points to note:

Connection and latency

1. USB 2.4 GHz dongle:
- The Arctis Nova 7's dongle is designed to establish a wireless connection with minimal latency.
- You can connect the dongle directly to the USB port of your Sony Bravia X80J. The TV should recognise the device and use it as an audio output source.
2. minimum latency:
- The 2.4 GHz dongle is specially optimised for gaming and multimedia, so latency should be very low. This is ideal for films, games and other media.

Spatial sound (surround sound)

1. Dolby/DTS support:
- The Arctis Nova 7 supports virtual surround sound (e.g. Dolby Audio or DTS) in combination with PC software or consoles, but support is limited by the TV.
- Android TVs such as the Sony Bravia X80J can output Dolby AC-3 or DTS audio if this is enabled in the settings.
2. television output:
- If the TV supports Dolby/DTS audio, it will output this via HDMI or optical outputs. However, the USB dongle will only support stereo audio or virtual surround sound decoded by the TV.
- For the best surround sound, you can check whether your TV has a passthrough setting to send Dolby/DTS data unchanged to the headphones.

Limitations

- The full functionality of 3D audio (such as SteelSeries' "Sonar" for PC) is limited to PC or dedicated consoles. On a TV, the spatial sound is reduced to stereo or Dolby/DTS formats.
- Some Android TVs have limitations with audio output via USB dongles, depending on the firmware. In most cases, however, this works without any problems.

Recommendation

- Test the headphones with the TV and activate Dolby/DTS in the audio settings of the Bravia X80J.
- If you want more spatial sound, you can alternatively connect the headphones to a Dolby-compatible soundbar or AV receiver, if available.
