...which is translated on right devices for listeners (6)
I believe the answer is:
radios
'listeners' is the definition.
Although both the answer and definition are plural nouns, I cannot see how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for radios that I've seen before include "Audio receivers" , "Communication devices" , "Broadcast receivers" , "Sets" , "Devices for sending or receiving signals" .)
