DO I NEED TO “BURN IN” MY HEADPHONES?
It is not absolutely necessary to burn in headphones. Whether or not a sound difference can be heard by warming up headphones depends on the headphones and on the individual’s sense of hearing.
Even without a burning in phase, it is absolutely normal for minimal changes in the sound from the headphones to be noticeable after a certain usage period. For example, the headphones might sound a bit softer in the highs.
Improvements in sound, where there actually aren’t any measurable changes, are also often perceived after a certain time. This is also known as the habituation effect. The human auditory system gets used to the sound from the headphones. Sound characteristics which initially may have been found to be annoying become less intensive over time or are even no longer noticed.
It is therefore highly advisable not to rely on the first (sound) impression and to form a judgement too quickly but instead to listen to the headphones over a longer period of time.
下面划重点地翻译一下：

1.完全没必要煲鸡

2.耳机用长了声音有变化是可能的，虽然测不出来

3.声音变化的原因有两方面，一方面是真的变了，另一方面更重要，你耳朵习惯了

4.所以不要听过一耳朵就评价耳机，用长了再说话，既煲鸡又煲耳朵

……本来我也是不信的……k3刚买回来，两边声场结像完全都不能在一起，就是带着听你感觉就跟有人从中间撕了个口子似的，特别明显，而且有首轻音，全程破音……就放那连着播放器插着电，放了一周我没管，因为真听不下去啊……一周多后有次终于再拿起来，结像正常了，至少不在劈成两半，换回那首轻音，ok不破音了，所以我觉得还是有用的你说结像你不懂，是我主管感受没问题，可是破不破音这可是简单的客观事实，刚买回来那天陆续听了4个小时，就是破音，一周后就是不破音了

一直自然听的路过而且明显感觉到听的时候有在煲耳朵

正解

并不认同，你可以买一个gr09试一试

有经验的老烧听耳机，一耳朵是可以听出素质的，但要决定一副耳机合不合口味，不听几十个小时是不可能的，看毒文就更没用了，大家小心点

感觉音量别太大正常听就好了，而且听时间长了，有变化也是那种每天好一点的超级缓慢变化，

这个很靠谱

耳机听久了会有变化是一定的，但觉得煲过耳机就一定朝你想要的方向发展就有点脑放了
