Mythical king; rich, yet a poor listener (5)

I believe the answer is:

midas

I'm a little stuck... Click here to teach me more about this clue!

'mythical king' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for midas that I've seen before include "Legendary king with golden touch" , "King of Phrygia who had a golden touch" , "Everything he touched turned to gold" , "Mythical king with golden touch" , "Legendary king whose touch turned anything to gold" .)

I've seen this clue in the Evening Standard.
