Impedance in headets

Do you know what makes a Polaris-series Plantronics headset different from an H-series headset?

They look the same.

They feel the same.

They smell the same.

The difference is . . . impedance.

????

Impedance is "resistance to alternating current" and is measured in ohms.

A Polaris headset has different impedance than an H-series headset.

This is why a Polaris headset can be plugged directly into a telephone that has an amplifier, but an H-series headset requires an external amplifier to work.

This is also why Polaris headsets cost more.

Interestingly, Chameleon call center headsets can be plugged directly into a telephone with a built-in amplifier (like the Norstar T-series of phone) AND it can also be used with an external amplifier.

I learn something new every day.
