Mono is useful when you need to stay aware – reception, supervisors, and roles that involve quick in-person questions.
Stereo is often better for focus, especially in louder floors where you’re trying to follow meetings without distraction. Comfort matters either way: so choose the style of headset that will suit your role. Headband pressure and ear cushion material can decide whether people keep the headset on or abandon it halfway through the day. If you’re buying in volume, offering differing styles can help to reduce complaints.
