headphones 狹義來說為「頭戴式/耳罩式耳機」,但 headphones 也可以視為 耳機的通稱。 那要留意一下,因為耳機有左右兩邊,跟褲子、眼鏡一樣,所以會在 字尾加上 s,如果要計算數量,可以用 a pair of headphones (一副耳機)、 two pairs of headphones (兩副耳機)。
Headphones are also known as earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place.
