Where does “headset” come from?

I appreciate the detailed instructions, but I cannot write this etymology summary because the chain provided contains only English words repeating in alternation, with no source language or ultimate origin indicated. A proper etymology requires tracing back to an earlier language (such as Old English, Proto-Germanic, or another ancestor). The chain "English set | English sett | English set..." does not establish where the word ultimately comes from, only internal English variations. To write an accurate one-sentence origin summary for "headset," I would need a complete chain showing the progression through earlier language stages—for example, something like: English headset | English set | Old English settan | Proto-Germanic *satjanan, etc. Could you provide the full etymological chain back to its origin language?
