Listening to a conversatin is a really easy job, if you're interested in the subject as well. But hearing beyond the words, that's something that's impressive. Talking to someone doesn't always have to be through words, it can also be through hand movements or voice changes. If someone says that he's happy with a low, distant voice this means that he actually is unhappy, even sad. This principle applies to almost any conversation. You don't need words to hear their feelings and emotions, you just need to hear beyond the voice.
