What does it mean to "Run" your headphone?

[Bagheera]

Hey all! I am a visitor from the USA, but I am Taiwanese so I can read Chinese no problem. Sorry I have to type in English though!

Anyway, I saw a lot of people talk about "Run" your headphone after you have bought it. What does it mean to "run" your headphone?

I have a pair of ATH-A9X by the way.

就像運動前熱身一樣，把肢體伸展開來才能好好發揮
也像引擎需要磨合，磨合一段時間之後，效能才能表現出來
不知道這樣的比喻是否夠貼切……

Umm, no that doesn't quite help.

What I meant was, does "Run" mean leaving the headphone on playing some music for days, which somehow actually changes its sound quality? Or does "Run" simply mean keep listening to your headphone until you are used to its sound quality?

站上的"文章收集"裡有解答，初次來到這個園地，還是先熟悉一下環境，潛水一下再發問比較妥當吧。

在玩車的有所謂引擎的磨合, 也叫 run-in 或 break-in...

基本的概念是因為這些東西牽涉到實體的機械式往復運動, 其物理特性在經過一段時間的運作之後, 會與一開始新品的狀態不同, 而漸趨一個穩態, 在很久很久以後它壞掉之前, 它會有好一段長時間是以這個狀態在工作, 而不是新品當時的狀態。由於我們關心的是它的「實力」, 所以我們希望藉由 "run-in" 來讓它渡過那個變化期, 達到它大概的穩態。

但是我個人的觀念則與上述不太相同。我個人並不特別喜歡或推薦別人去做所謂 "run-in" 的事情。當我向朋友介紹這件事時, 我都只希望他們了解到這種現象--這種變化過程--的存在, 如此一來他們不會對於新器材表現時常變化感到奇怪或困擾, 但是, 並不要刻意去 "run-in" 器材--我是覺得自然而然讓器材的筋骨鬆開會比狂操猛練逼出來的東西要好。

加速 "run-in" 也不是一無是處, 如果要測器材的話, 它就變成必要的事情, 不稍微 run 一下, 評器材是很難有個準頭。

smb: 文章收集??? Where is that? Can't find it on the Index.

JamesT: Thank you! I see. For a headphone like the A9X, about how long will it take for it to get "run-in" and under what condition (run on CD-player? Soundcard? Amplifier?)?

左側menu有個"文章收集"，其中Run in那篇文章裡提到『由於喇叭單體、耳機振膜剛出廠的時候，懸邊和構造並非百分之百的沒有毛邊，動作也比較生硬放不開，所以需要使用聆聽幾個禮拜甚至幾個月之後，聲音才能完全的發揮原來的水準。』，雖然不知道上面那段是否完全正確。引擎的磨合我們也是稱為Run in，真的是很相似的觀念。
