"저는 라디오를 들어요."
Translation:I listen to the radio.
What is Korean for I hear a radio? This is not a correct translation for the senence above, per Duolingo.
I would translate "hear" as 들리다 rather than 듣다, it's kind of like passive vs active voice in Korean when it comes to those two words. So "I hear a radio" would be 저는 라디오를 들려요
