1 review for Poly DA85 USB Adapter

  1. RDH (verified owner)

    Works pretty well and it has extended the life of my Starset headset H31CD since we converted to VOIP. I am having problems configuring some of the settings to “do nothing” when I disconnect with the quick disconnect and to allow my PC’s speakers to play sounds outside of Teams meetings or VOIP calls.
