1、怎么改造JVC-RX900步骤1：拆掉耳棉这个比较简单，看图即可。注意的是作者建议从耳机最厚处着手，比较好拆吧。步骤二：去掉调音纸拧掉螺丝，去掉覆盖出音孔的塑料片（声学透镜？）。下面覆盖的黑色调音纸就是导致听这个耳机的人感到中高频有凹陷的原因。下面的部分就比较棘手了：用指甲把调音纸周围轻轻刮起来，不要试图去将整个调音纸都揭去，留上一薄层相对而言更加容易点。左图是揭下来的调音纸，在耳机上还留有薄薄的一层。理论上说，你可以通过揭掉出音孔上覆盖的调音纸来获得额外的n多细节层次。但我建议你在揭掉他们之前好好考虑下，毕竟留他们在那里可以阻挡头发和灰尘从出音孔进入。最后将拆下来的塑料片装上。步骤三：Dyn
2、amat单元后壳拧下上面右图标示出的三个螺丝，小心的打开耳机单元。注意不要把线弄断。你现在可以看到单元的内部了。本步改造的目的是解决薄塑料制成的单元腔体共振的问题。首先，用Dynamat剪2个直径21/2”的圆形。揭掉Dynamat后面的贴纸，将他粘在单元外壳中心，注意一定要压紧，要拍出所有的空气，这是非常重要的。步骤四：Dynamat单元后壳四周（可选）鉴于Dynamat将会增加耳机的重量，因此本步骤为可选，或者部分实施。将Dynamat剪成1/2”宽的小条，粘在耳机后壳周围。步骤五：由于有一些多余出来的Dynamat小片，因此我决定进行下一个步骤。耳机单元背面磁铁有1便士大小。用Dynam
3、at剪成一个这么大的圆，确保留一个缺口，使耳机单元背面磁铁上的洞露出来。把圆放在单元背面磁铁上粘牢。步骤六：将单元周围用Dynamat贴满（可选）由于重量原因，本步骤可以省略或部分实施。基本思路是为共振的薄塑料提供更大的阻尼，使得中频更加清晰。将Dynamat剪成小条，黏贴在单元周围你想放的地方。但要确保两个部分留出空隙。一个是单元背面的三个通气孔，这地方允许空气流动，使耳机振膜震动更自由。我相信覆盖此处会导致影响音质。（上面右图1）另一个是耳机单元上部的凹槽，贴了就不能把耳机外壳合上了。（上面右图2）步骤七：吸音棉在单元外壳内填充薄薄一层吸声棉后，可以将单元外壳合上。就像markl改造他的D
4、5000（感谢markl，他给我此次mod的启发）。只放薄薄一层是很重要的，因为放太多会减少低音。你可以按照你的喜好进行调整。步骤八：将耳机恢复如初最后的步骤就是把单元外壳合起来，注意不要拽到耳机线OK了。现在静下心来去享受全新的声音吧。只需要几块钱的材料，3、40分钟时间就可以让你不相信这是一个60美元的耳机（发出的声音）。至于说声音，我完全相信类似价位中找不到可以和改装后的RX900媲美的耳机。说实话，在很多方面，我觉得他超过了我的爱丽丝MS-1s（Alessandro MS-1s）和拜亚动力的DT-880很显然说的有点多了。用他听原声吉他和贝斯更加自然，而其他两个无法达到。此外，（这个耳
5、机）低频让人意想不到，即使音量开的很低。此前我从未在如此低的水平感受低音的冲击。如果你正在尝试这个耳机，并且对压倒的、失控的低音和凹陷的中频感到失望。那么我相信，通过上述简单的修改，您可以得到很大的惊喜。关于Dynamat：由于我不知道原始Dynamat和极端Dynamat之间的区别，我订购了原始的Dynamat，以节省资金。我现在发现由于原始的Dynamat一面是橡胶，能更好的吸声，而不是反射（极端的Dynamat表面是铝箔）；但不好的是原始的Dynamat更加重。关于重量：首先我们知道，修改RX900增加了重量，这就是我把一些步骤作为可选的原因。我相信，可选的步骤会提高音质，但他们非常重。
6、长时间使用后，你的脖子会非常痛。我的计划是，先试听几天，如果确实太重的话，打开耳机将步骤4和6删去。更新：长时间佩戴这个耳机太重了。因此我打开耳机去掉了额外的Dynamat，除了步骤6中耳机单元周围的一圈。这样耳机轻多了，并且我听不出声音上的区别。现在我只建议在磁铁上、单元后壳（步骤三）以及步骤六的内圈（仍然是可选的，尽管我是猜的）放Dynamat。提问：是否可以只进行步骤二？回答：步骤二是改善中高频，增加泡沫小块（可能就是那个Dynamat）为了使声音更均衡。正如jaudio说的，试着加上泡沫。我第一次试着在壳体内加两块双面泡沫胶带，虽然最后并未采用，但我始终认为这是值得的。如果你想进一步减
7、少低音，多放点吸音棉吧。JVC HA-RX700 ModsMOD 1JVC HA-RX700 Foam modCut from a sheet of foam this simple mod will not only improve the comfort but improve the soundstage due to the speakers being pushed back further from your ear. The result of a larger soundstage; better musical separation, less shrill highs, m

The inner circle the size of the size of the opening, any smaller and it might tickle your ear!- Start to work the foam und

This should add sound isolation and cut out those unwanted reverberating sounds bouncing of the plastic.This is still a work in progress and Ill update once Ive complete it fully. Right now I only applied this mod to the r
13、ight side and am currently listening to the difference. What immediately struck me is how much quieter it made the right side, I had to balance out theheadphonesfor the first time; L: 85-90% / R: 100% so its made the right side 10%-15% quieter overall. Female voices are notably still louder in the u
