Got closer to listener in wrong end (6)
I believe the answer is:
neared
'got closer' is the definition.
(I've seen this in another clue)
'listener in wrong end' is the wordplay.
'listener' becomes 'ear' (body part which hears or listens).
'in' indicates putting letters inside.
'wrong' indicates anagramming the letters.
'end' anagrammed gives 'ned'.
'ear' put within 'ned' is 'NEARED'.
'to' is the link.
(Other definitions for neared that I've seen before include "Approached, drew close" , "Approached, came close" , "Got closer" , "Drew nigh" , "Drew closer to" .)
