Help? Are all of the Plantronics H Series Headsets voice tubes and ear cushions compatible with eachother?

Q: Do all of the Plantronics H Series headsets use the same voice tube and ear cushions?

A: Some of the headsets do share the same voice tube and ear cushions but not all of them. The best way to find out what accessories your headset will need, is to look up your item on our website and then scroll down the page to see the list of accessories we carry for your headset.
