Hello, that is correct, it works without software. You can also configure the headphones via the app on your mobile phone.

I first used the headphones without the software. Everything worked without any problems. However, I wanted to deactivate the automatic call acceptance function (e.g. as soon as you put on the headphones, a call is automatically accepted). The software is needed for this.

has worked for all of us...4 of us are using the headset...USB stick in recognises everything automatically without admin rights...no installation required...nothing. You just can't install the Poly software...but you don't have to...except for a firmware update...but you can do that at home...
