Got closer to listener in wrong end (6)
I believe the answer is:
neared
'got closer' is the definition.
(I've seen this before)
'listener in wrong end' is the wordplay.
'listener' becomes 'ear' (body part which hears or listens).
'in' means one lot of letters goes inside another.
'wrong' is an anagram indicator.
'end' anagrammed gives 'ned'.
'ear' inserted 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" .)
