Shall I use singular verbs or pulral verbs for headsets in the following sentences? Please check it for me. Thanks.
yesterday I bought a new pair of headsets. They are not working so, I will have to return them and get a new pair tomorrow.

A single headset contains 2 ear pieces and may also contain a microphone.
A pair of headsets would be enough for two people (one headset each) and would have 4 ear pieces in total.
