Chief ready for speaker and microphone ensemble (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
headset
'speaker and microphone ensemble' is the definition.
I can't judge whether this definition defines the answer.
'chief ready' is the wordplay.
'chief' becomes 'head' (synonyms).
'ready' becomes 'set' (set can mean ready or prepared).
'head'+'set'='HEADSET'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for headset that I've seen before include "Combined earphones with microphone" , "listening equipment" , "communication aid" , "Bicycle front bearing assembly" , "Communication kit" .)
