| Why You Might Not Want This One |
| If you need ANC |
Poly publishes none for the 4320 — choose a headset that states hybrid or adaptive ANC |
| If you need a cradle in the box |
Not included here; the charge stand is a separate order line |
| If your site is Zoom or Webex only |
The Teams certification adds nothing — the UC article is the cheaper match |
| If you need 3.5 mm |
No analog connection is published for this model |
| If you share one headset across shifts |
A DECT model on a base station suits shared desks better |
