This version comes with the BUA200 USB BT dongle. It’s capable of HDVoice when used with the built-in BT radio on a similarly capable host. I was not able to get it to pass HDVoice to the BUA200 connected to a desktop. It also lacks A2DP, which means it’s great for voice calls but you cannot use it to listen to music or podcasts via your cell phone.
Even so, this is good price on a high-quality, HDVoice-capable BT headset that commanded $120+ not so long ago.
