woah, it can switch between bluetooth and the lightspeed dongle. so you can switch between pc and fone just holding down 1 button for 3 seconds.
that's so convenient.
scenario:
tp4 plays dat vampire survivor on pc on lightspeed, needs to do costco run for m0ar pepsi, hold button 3 seconds, connect to fone, go outside, the headset instantly repels all fellow hughmahns, get sodas, come home, hold button, back on vampire survivors.
