Poly Voyager 4310 UC Wireless Headset (Plantronics) - Single-Ear Bluetooth Headset with Boom Mic for PC, Mac & Mobile - USB-A Adapter Included - Compatible with Teams, Zoom, Skype - Ideal for Office, Call Center & Remote Work - Black

Arch Linux (Kernel 6.3.9, PulseAudio 16.1).Simply put, this works great. Using the included BT700 USB-A bluetooth adapter (comes pre-paired with the Voyager 4310 UC headset). I also paired the headset to my Android device. Connecting to both devices simultaneously is easy and works great.The included BT700 bluetooth adapter has the advantage of providing an LED status indicator. The LED on the BT700 is BLUE when connected, RED when mic is muted, and OFF when the headset is off. This visual feedback is quite nice, especially since the mute button (located on the microphone boom) is a momentary switch. The headset will additionally announce (vocally) that the microphone is muted when the momentary switch is pressed and will, likewise, announce that the mic is unmuted if pressed again. If you attempt to speak into the mic while muted, the headset will provide you with vocal reminder that you are muted. This is all done in hardware.It is important to note that if no application is currently using the mic as an input device, the mute button on the headset will do nothing. It is not broken. Just connect to a Zoom call, a Discord voice channel, or even your system's audio control panel (anything that actively read's from the mic) and the mute button will work fine as intended.Headset earpiece volume is controlled independently of the current main system output volume using the + and - button on the earpiece. This is very nice if your computer uses speakers at the primary output device but you have set your voice/video app to use the headset for output. The kernel will adjust the headset's reported volume level as a result of pressing these buttons (+ and -), not the currently selected primary output device. This is an incredibly nice touch.On this topic, Poly's Acoustic Fence technology works surprisingly well. Playing reasonably loud music through my computer speakers, people I'm speaking to through the headset can only hear my voice. Microphone quality is clear with good dynamic range. Acoustic Fence does not appear to provide a "muffled" sound like some other noise cancelling microphones I have used.Audio quality through the earpiece is astonishingly good when using the included BT700 dongle. Bass is surprisingly good, dynamic range overall is good. Sound comes through very clear. You can happily listen to music. The sound is not "tinny"Charging stand is great. Very nice weighting -- it won't slide around your desk unless you move it. Docking and undocking is fast and simple. Connection is facilitated through an additional set of 5 contacts, which are well hidden on the headset. Insertion force is zero. Headset is nicely guided into position. No glaring design issues.Overall a strong recommend if you run Linux (or don't). Truly an amazing headset.
