In foreign parts manages to be heard (8)
I believe the answer is:
overseas
'in foreign parts' is the definition.
(I've seen this before)
'manages to be heard' is the wordplay.
'manages' becomes 'oversees ' ('oversee' can be a synonym of 'manage').
'to be heard' indicates a 'sounds like' (homophone) clue.
'oversees' sounds like 'OVERSEAS'.
(Other definitions for overseas that I've seen before include "Exotic" , "In a foreign country" , "In foreign parts" , "abroad - with 12a" .)
