The term headphones generally refers to a device that allows a single user to listen to an audio source privately. Specifically, headphones are a pair of small loudspeakers worn around the head over the ears. Modern headphones have soft earpads covering the loudspeakers, which not only provide comfort but also increase audio quality. These pads also help block out noises from outside and keep sounds produced by the headphones from being heard by others.
As audio systems became smaller, so did headphones. Some people now prefer tiny speakers called earphones. Inserted into the ear canal, earphones come with cushions and provide a more direct connection to the sound being played. A similar device called earbuds differs from earphones in that it lacks cushions. Lightweight and portable, earbuds—both wired and wireless—and earphones are most suitable for those who can’t live without music. However, they may be uncomfortable to wear for long periods of time.
Headphones with different functions have also appeared. One example is headsets equipped with microphones that can be moved at will. Headsets are ideal for conducting online meetings and playing online games. Cutting-edge devices like bone-conduction headphones, which send sound waves through a wearer’s skull without covering the ears, have also amazed people. As audio technology continues to advance, it’s anyone’s guess how future generations will enjoy their music.

多虧二十世紀可攜式音樂播放裝置的突破，現在有了方便隨身攜帶的輕量耳機。現在很常看到人們戴耳機邊走邊聽音樂，而耳機有著各式設計來滿足人們的不同需求。
headphones這一詞通常指的是讓單一使用者能私下聽音訊的裝置。具體來說，headphones（譯註：中文譯為頭戴式耳機）是一種能戴在頭上、放置在雙耳上的小型喇叭組。現代的頭戴式耳機有軟墊覆蓋住喇叭，這不僅提供了舒適還提升了音質。這些軟墊也有助於阻絕外來的噪音，並讓耳機產生的聲音不讓他人聽見。
正如音響系統變得更小，耳機也是如此。有些人現在偏好稱作入耳式耳機的微小喇叭。這種耳機可以插入耳道，有著墊子且提供了與播放的聲音更直接的連結。一款與入耳式耳機相似的裝置被稱為耳塞式耳機，不同之處在於沒有墊子。輕便又易攜帶的耳塞式耳機 —— 有有線款也有無線款 —— 以及入耳式耳機最適合沒有音樂就活不下去的人。但是長時間戴著這些耳機可能會覺得不舒服。
有著不同功能的耳機也出現了。一個例子是配備有可任意移動之麥克風的耳機麥克風。耳機麥克風適合進行線上會議以及玩線上遊戲。像是骨傳導耳機——透過穿戴者的頭骨傳遞聲波而不會覆蓋耳朵 —— 等最新的裝置也令人大為驚奇。隨著聲音科技持續發展，未來世代會如何享受音樂，誰也說不準。

Historians are rethinking the way the Holocaust is being presented in museums as the world marks the 80th anniversary of the liberation of the last Nazi concentration camps this month. Shocking images of the mass killings of Jews were “used massively at the end of World War II to show the violence of the Nazis,” historian Tal Bruttmann, a specialist on the Holocaust, told AFP. But in doing so “we kind of lost sight of the fact that is not normal to show” such graphic scenes of mass murder, of people being humiliated and dehumanized, he said. Up to this
When people listen to music today, they typically use streaming services like YouTube or Spotify. However, traditional formats like vinyl records have regained popularity in recent times. Vinyl records are circular discs that store music in grooves on their surfaces and are played on a turntable. As the turntable’s needle runs along these grooves, it picks up vibrations and translates them into sound. The history of vinyl records dates back to the late 1800s, but material and technological challenges delayed mass production until the 1950s. Despite early versions having short playtimes and poor sound quality, vinyl records introduced a new era
