N a small earphone worn in the ear for use with a mobile phone (配合手机等使用的)耳塞
If you really need music as a distraction, keep the volume low and one earbud out.
如果你确实需要音乐来调节，请调低音量并只一只耳朵戴耳塞。
If you absolutely must use your iPod on the run, just use one earbud or keep the volume low so you can still hear what's going on around you.
如果你实在必须在跑步中听ipod，那就只听一边耳机或把音量调低，这样你仍然能听到周围发生了什么。
They’re stylish, of course, and they adjust in three ways: the hook opens and closes, the earbud slides higher or lower, and the earbud rotates in or out.
这种耳机的外观当然很时尚，共有有三种调试方法：挂钩可打开和关闭，耳塞可上下滑动，耳塞还可以转进和转出。
