Sony MDR-R10 Repair Back From The Dead
We got an email about a pair of Sony R10’s where the customer felt there was something wrong with his headphones. After speaking with him for about an hour on the phone listening to all the symptoms and their past history I suggested him to mail them in to have us give them a look over. Once we got the headphones in I noticed they were only off by 4 serial #’s from a pair I used to own. I plugged them in and gave them a listen instantly noticing there was something terribly wrong with these headphones. Muffled, congested, missing entire frequencies of the sound spectrum, and absolutely bloated bass were among the things I instantly noticed. I stopped the music and unplugged the headphones having no idea how serious the damage was going to be.
I remove the ear pads from the headphones and noticed a few things. First the pads were no longer held on by their stock material. Instead replaced with what seems to be double sided sticky tape. I also noticed that pieces of the urethane ring were ripped off and still on the pads. Also, I saw that the filter attached to the pad was torn at the stitches from the pads. The only way I know this can happen is if you have no idea how to remove the ear pads. The ear pads if removed properly cause no damage to anything in the headphone or the pads themselves. The stock material used to hold the pads down to the housing can be reused without question.

At this point since I know these were modded before the drivers should be easily removed so long as they were not glued into the housing. I removed the right driver and then the left driver from the wooden cups. I couldn’t believe what I saw. The right driver seems to be fine, but the left driver instantly caught my attention.

Someone has seriously messed up removing the driver previously and then attempted fixing the problem using epoxy glue!
The voice coil of the left side driver was torn completely when removing the driver. Based on how the drivers are installed in the housing this is because either an improper tool was used or a tool was used improperly. Trying to fix the voice coil they removed the entire driver dampening and filter from the back side. The worst part is that it doesn’t seem that the voice coil extensions were ever actually soldered to the voice coil, but simply laid down to touch and glued down with epoxy which is impossible to remove without further damage to the voice coils.
At this point I had no idea what to do, but started running tests to try and figure out if at least the repair was feasible. I contacted the owner of the headphones shortly after telling him about what I had discovered. He was very surprised and quite upset rightfully so.
After about 6 hours and numerous different tests I discovered where everything went wrong and where the problems were. I tested the right driver separately and it worked perfectly, but as soon as it was connected back in conjunction to the left side on the same cable it started to give me all sorts of problems again. I tested the stock cable and it was ok so I knew this for sure was all tied into the damaged left driver. I went ahead on a hunch and decided to measure resistance of the housing (the R10 driver housing is metal so it is conductive) and the voice coil wire. To my surprise I was actually getting a reading. I started trying to figure out where it was connected and it lead to the side marked in blue which the previous modder put on there. This normally is the ground or return of the voice coil wire. I went ahead and removed as much of the fix from before and reconstructed as much of the driver as I could testing resistance to the housing the entire time finally getting it done with no resistance to the housing. Great news as it seems the driver was at this point fixed I went ahead and ran tests of the driver against the right driver and was still getting incorrect measurements. Instantly it hit me. When they removed the driver they broke the voice coil and didn’t fix it so they had no idea which was the correct phase of the driver. I swapped the + and – and next thing I know the left driver is giving me nearly the exact same readings as the right side. I went ahead and secured the entire repair and installed the torn off dampening and filter back onto the driver and tested again getting the exact same measurements for both the left and right side. I thought to myself great this is finally fixed and how happy the customer will be when he hears the great news.

The following day I took apart the rest of the headphone only to find more and more things wrong. Once the wooden housing was removed from the headband assembly I noticed that the stock cable was reattached using hot glue all over. Having modded a hand full of other R10’s I knew for a fact this wasn’t right. I went ahead and removed all of it from every place I found it. I also found small wooden chips inside the left ear cup which was removed in the cleaning process of this headphone.

I spoke with the customer and he was amazed with the fact that it was repaired and asked me to recable them with the APureSound V3 cable using Super Nylon and a Furutech 1/4in plug.
You can see below the repaired driver on the right and the unharmed driver on the left. Note that the + and - is now switched on the left side driver because of how they previously attempted to repair them.

As always here at APureSound all of our cables are installed right onto the driver with no splicing or connection of any type.

The entire headphone was reassembled, cleaned, the leather conditioned, and are back to being truly one of the finest headphones ever made.

Here is a comment from the owner of these R10’s.
“I cannot begin to tell you how excellent your cabling has made these headphones sound.Way beyond my expectations.Thank you very much for everything. Again thank you very much you are a true professional.“
The initial recable was done by JenaLabs which is where all the damage happened as well. You can read what JenaLabs had to say about when they recabled them HERE
It’s ironic how they are able to point out other companies who do not solder directly to the drivers, but mess up doing it themselves.

我是来顶98的 以前让他帮忙修过240DF 哈哈
98的帮助实在是雪中送炭
我之前那只DT931修了一次，一直听的很好，然后又是不小心使用到出问题。后来实在是太懒了，没有邮寄给他而直接在广州找了个人修理，然后就彻底报废。
好在这次在德国新买了一只成色好的。

你也这样喜欢931？:lol
初烧时候买了一只，好像是2007年还是什么时候买的。一直用到报废。
对白牙的其他耳机，兴趣聊聊。广州有玩8PR的曾兄，对DT931情有独钟，可惜他想拿我那只的时候，我那字已经是老残之身了。
这次这只应该能用很久

这个驴耳朵真有那么好？不相信。
它好的地方在于：
细腻度和静电是两种风格，但是难分胜负，是动圈耳机里一流的细腻度；
微动态极佳；
音色带有一种富丽堂皇、雍容华贵的感觉，可以理解为传说中的贵气；
对气氛的营造和音乐的融入感非常棒。
如果HD800卖1万，那R10按照它当年的售价（卖2万出头）是没有任何问题的。只是现在价格一路飙升，谁叫它停产了呢。
R10的里面原来是这样的:L
这是一篇 APureSound檄文呀，jena lab是被搞了一道。但是从第一张图里开始就没出现过jena labs的线，硬说是jena labs改线搞坏的，没有说服力。而且我不相信jena labs的做工是这样的，从jena labs的网站看，他们改r10的手工很漂亮。
楼上的那句台词是建国大业里的吧
路過一下:lol :lol

哇，求分享。。。。
當初這件事件我有在headfi看到,也跟進過,應該沒錯是jena labs的問題,記得jena labs負責人和事主都有回覆.當時也挺火爆的.
