Poly Voyager 4320chat_bubble_outlineFrom real comments

Call and mic quality impress heavy daily users. Multiple long-time users who spend 7 to 8 hours a day on calls say the 4320 delivers excellent call quality and strong mic performance, with one calling Poly's mics and design the best in the category. A truck driver and remote workers both praised comfort during extended wear, and one user specifically credited the headset with eliminating background dog barking from voicemails. Compared to pricier alternatives like the Focus 2, reviewers felt the 4320 offered similar day-to-day performance for meetings and calls at a noticeably lower price point.

Bluetooth and dongle pairing frustrate a large share of owners. A recurring theme across comments is trouble connecting the headset: users report the BT700 dongle failing to pair, Bluetooth connections that never complete, needing to unplug the USB dongle to reconnect, and confusion switching between phone and PC audio sources. Some also hit Windows 11 compatibility problems, with Poly support reportedly confirming the series was not yet fully supported. A few users had their headset or dongle simply stop working entirely, leaving them unable to connect wirelessly at all.

Noise cancellation and durability are inconsistent over time. While some users found the noise cancelling effective, especially when wired, others said it barely reduced background chatter or music compared to older Poly models, and noted it only seems to work during calls, not recordings. Several long-term owners also reported hardware failures after a year or so of heavy use, including a broken mute button, a dead mic boom, one-sided audio loss, and batteries that degraded quickly, requiring risky aftermarket replacements.
