Sounds like fruit, to the ear (6)
I believe the answer is:
plumbs
'sounds' is the definition.
(I've seen this before)
'fruit to the ear' is the wordplay.
'fruit' becomes 'plum' (plum is a kind of fruit).
'to the ear' becomes 'bs' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'plum'+'bs'='PLUMBS'
'like' acts as a link.
Can you help me to learn more?
(Other definitions for plumbs that I've seen before include "Reaches or experiences, say the depths" , "Sounds" , "Gets to the bottom of" .)
