Is it the same product as this one: https://www.galaxus.ch/de/s1/product/poly-voyager-5200-uc-kabellos-kabelgebunden-usb-a-office-headset-5817778 The name is the same, but when comparing the two, one has bluetooth and the other does not. But it does in the description. I can't figure it out. Thanks for your support.
