Telephone component for a listener to music (8)
I believe the answer is:
earpiece
'telephone component' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'a listener to music' is the wordplay.
'a listener' becomes 'ear' (I've seen this before).
'to music' becomes 'piece' (piece is a kind of music).
'ear'+'piece'='EARPIECE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for earpiece that I've seen before include "Through which one may listen" , "receiver" , "Part of a telephone" , "box?" , "for audibility" .)
