关于一个小米圈铁耳机Pro以及一个索尼WALKMAN（NWZ-B183F）的问题
推荐回答（2个）
你好！我这几天才买了圈铁Pro，插上B183F之后发现底噪非常大，已经大到不能听了。奇怪的是重新插拔后底噪恢复正常并且控制得不错，但是一换歌就又“啪”地一下出现了底噪。
这几天我在网上搜索的时候看到了你这个问题，首先分享一篇帖子https://tieba.baidu.com/f?kz=4991806222&mo_device=1&ssid=0&from=2001a&uid=0&pu=usm@1,sz@320_1003,ta@iphone_2_6.0_1_11.9&bd_page_type=1&baiduid=E67EC8D1316D26E8F50EC9E462161E44&tj=www_normal_1_0_10_title&referer=m.baidu.com
我认为底噪大的原因有二。一是B183F由于成本限制，电路板的印刷控制不到位导致本来机器的底噪就很大，这个你换几条耳机都能得到结论，毋庸置疑。
二是圈铁Pro本身的问题。这款耳机本身非常优秀，能达到三四百价位的水准，但是它非常高的灵敏度以及20-40000Hz的动态范围决定了在高频，也就是在噪声这块非常灵敏，如果器材本身不行，反而会放大底噪。
我觉得这几天的听感下来这款耳机的解析度和声场都挺不错，中低频比较饱满，但高频略有瑕疵，这可能也是底噪大的原因之一。与我听过千元价位的索尼比较除了饱满程度和解析度、高频的瑕疵以外别的地方已经比较接近索尼的水准了。而且我手头上还有飞傲x3k播放器，用这个推耳机之前B183F的底噪问题都没有了。
所以这个问题我认为应该是MP3播放器的问题，建议你换一台好一点的机器试试。如果要推荐的话，100到300这个价位几乎都是主打重低音的耳机，你要是喜欢重低音可以试试AKG K420,这款09年发布便享誉全球的耳机很有性价比的。当然一咬牙买一款好的也是不错的，索尼HR系列的产品都不错，嫌贵可以在618买，打对折的啊。
可能你的问题已经解决，我也就是想和大家多讨论讨论。
首先，用底噪来评价耳机好坏自然是一个错误的观念，当然对于强迫症，确实可能是个问题。
底噪来源是b183f，这是毫无疑问的。 当然，是因为xba-c10属于低阻高敏，所以才会放大了这种声音，耳塞的进步会暴露前端的问题，所以升级实际是个有讲究的事情。
