Surrounding makes men a bit confused (7)
I believe the answer is:
ambient
'surrounding' is the definition.
(synonyms)
'men a bit confused' is the wordplay.
'confused' indicates an anagram.
'men'+'a'+'bit'='menabit'
'menabit' is an anagram of 'AMBIENT'.
'makes' acts as a link.
(Other definitions for ambient that I've seen before include "Surrounding, temperature perhaps" , "relaxing type of music?" , "relaxed atmosphere" , "Relaxation music" , "to do with circulation" .)
