Think beyond the headset itself. Normalise a small number of models, ensure that they work with phones and soft phone operating systems, and plan spares with high-utilisation teams. Enquire about the way in which firmware updates are handled, and whether replacement parts such as ear cushions are easily accessible and whether warranty support is available. For a consistent user experience, keep wearing styles predictable and provide simple guidance on mic placement and call settings. This reduces support load and improves call quality across the whole organisation.
