Surrounding makes men a bit confused (7)
I believe the answer is:
ambient
'surrounding' is the definition.
('ambient' can be a synonym of 'surrounding')
'men a bit confused' is the wordplay.
'confused' is an anagram indicator.
'men'+'a'+'bit'='menabit'
'menabit' anagrammed gives 'AMBIENT'.
'makes' is the 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" .)
