With the (exception) of those who are unfortunately handicapped or (disabled), most people in the world have the same five senses of hearing, sight, smell, taste and touch. Some people, however, develop one or more of their (senses) up to a higher level. For example, a wine (connoisseur) may be able to tell exactly where and when a certain (vintage) wine was made just by the smell and taste. Someone who "has a good eye for" art, may be able to (discriminate) between valuable and worthless paintings. (Likewise), someone who "has a good ear for" music may be able to tell everything about a piece of classical music after hearing only the first three notes. Others may "have a good ear for" languages, and learn how to speak in (several tongues). In other words, this idiom can be applied to any kind of (auditory) skills.
lend me your ear(s) 请听我说
to play it by ear 见机行事
to keep one's ear to the ground 察觉并留意週遭状况或他人感受
