Question about Logitech G G435 Lightspeed

Unfortunately, I don't know where you can get the "stick". However, the headset also works via Bluetooth. You could simply connect via Bluetooth if you already have Bluetooth (e.g. laptop) or buy a dongle (e.g. https://www.digitec.ch/de/s1/product/tp-link-ub500-sender-bluetooth-audio-adapter-16644981).

Thank you
