苹果出品：全新耳机EarPods 官方宣传广告

The human ear is so unique. No two are alike. Making one headphone to fit everbody’s ears would be like trying to make one pair of shoes to fit everybody’s feet.
人的耳朵是如此独特，没有任何两只是完全相同的。要制作一款适合所有人耳型的耳机，无异于制作一双适合所有人脚型的鞋子。

I mean, it’s impossible.
这是不可能的。

But that's exactly what we've tried to do with the new EarPods. Everything about their design is focused on delivering incredible sound and comfort. As part of an exhaustive research and development effort, we three-dimensionally scanned hundreds of ears and looked for a commonality. From that, we were able to determine a common volume. This was our starting point to developing a form to fit a broad range of ears.
而这正是我们通过全新EarPods试图做到的。其中的每个设计细节，都致力于达到出色的音效和舒适度。在细微详尽的研发过程中，我们对数百双耳朵进行了三维扫描，并从中寻找共性，由此确定人们通常的耳道容积。我们以此为出发点，来研发广泛适合于各种耳型的耳机外型。

The shape of the EarPod is actually defined by the geometry of your ear, they raise comfort in your ears, but they don't create a seal the way other in-ear headphones do.
EarPod的形状实际上取决于耳朵的几何构造。它们可以舒适的放入耳中，但不会像入耳式耳机那样带来堵塞感。

EarPods to design unintentionally series with unique purpose.
EarPods的设计旨在将声音直接引入耳道。

To optimize the acoustics, we've built in a series of ports, each with its own unique purpose.A port in the back tunes midrange frequencies and provides a consistent listening experience from one person to the next. To provide rich, powerful bass, we've built ports into the stem that actually work in sympathy with the speaker. By letting airflow in and out of the acoustic chamber, they relieve pressure and allow the speaker to allow more freely, producing greater, low-frequency sound.
为了优化音响效果，我们在耳机上设有多个气孔，每个气孔都有其独特的功能。耳机背面的气孔用于调节中音频部分，并保证每位使用者都能获得流畅一致的听觉体验。为了展现浑厚的低音，我们在耳机柄部也设有气孔，实际作用是与扬声器产生共鸣。这些气孔让空气自由进出音腔，释放耳机内的压力，让扬声器工作更自如，从而产生更浑厚的低音频声响。

Sound is so important to the way you experience an Apple product. So we wanted to make a headphone that was absolutely the very best it could be.
音质对你体验Apple产品来说至关重要。因此，我们希望打造一款尽善尽美的耳机。
