Since I don't game, I can't really answer the question of whether they are suitable for this. However, I can confirm that the headset can be connected to the computer both with the USB-C dongle and via Bluetooth. It is also no problem to connect two devices (e.g. computer & mobile phone) at the same time - regardless of whether it is a dongle/BT or BT/BT. Sound quality and ANC are very good, although not quite on the same level as the Sony WH-1000, but you get a microphone from Jabra that is worlds better! With ANC, you have the option to turn on "PassThrough". In normal "music mode" you can only switch PassThrough on or off. For conversations, you can gradually adjust the "Listen" option, i.e. set yourself how much of your own voice you want to hear while talking on the phone (or gaming?).
