Fostex T20RP mkII

ericcho

最近有時間，買了這Fostex T20RP mkII玩下，未mod聽下先，唔錯呢，音樂感幾好，不是網上常說的唔mod就是好差喔。
聽一排先mod下，好多改法都是reversible的。
其實T20/40/50RP mkII只是Open/Closed/Semi-Open的分別，driver都是一樣的，所以選了這T20RP mkII，最便宜，就算不去mod，才7千多yen，也能聽下喔，聲音飽滿溫暖，是低頻有點多。
各位師兄有mod的經驗可以分享下！

週未有空，好奇心驅使下，參考網上的資訊，加上自己的一點想法，進行了此極簡單的改裝…











改裝後…
聲音的改善，真有點出奇… 聲音細緻不少，分離度、分析力、聲場、定位都改善，低頻受控了點，基本上是全面的改善。
這Fostex比不少動圈顆粒感少，聲音平順、連慣、飽滿，真的不錯！
明白何解多年來咁多玩家改裝，但不明白原裝何會賣咁平，原設計浪費了這orthodynamic單元。
其實這Fostex幾靚仔。

CHING, these are good headphones! I have done a mod similar to yours, but on T50RP

I bought a Fostex T50RP headphone from Amazon for US$110 because of its big potential to be modified into a decent one. Its planar-magnetic drivers are really amazing, but the design of the cup limited their performance. The modification can take less than one hour to finish. The result is very good, worth the US$110 or even much more. The most important thing is that, it can really give the smooth sound signature of planar-magnetics!

People in the forum have suggested a large number of possible modifications, but I just did some simple ones:
- filled the space with modeling clay and cotton;
- replaced the earpads with Shure HPAEC840.

Filling with modeling clay and cotton

I may change the headband as well if I can find a good replacement.

Driving with FiiO E12

The headphone is hard to drive. I use a FiiO E12 to drive it because of its large current output limit and its nice bass boost feature (even with the modification, the bass is still a bit faint).

再改動了一下，清晰度、定位、聲場進一步改善，暫時幾滿意，好玩。

這次背殼內則貼上吸音綿，換了較大較厚的皮耳罩(試過更厚的king size，配帶非常舒適，但聲音亂… 絨耳罩清晰度最好，但低頻減少)，也封了大部份氣窗。

Hi C Hing,

How is the modified T20RP mkII or T50RP in comparison with AKG K702 or K712 etc. I am considering to have one for modification. Many thanks.

玩耳機個人著意的是timbre，其實耳機到了一定水平，好多時選的重點是timbre，使用最多的就是最好的耳機。

AKG玩過的K280、K601、K701和K712pro都賣了，現在就留下K340和K240mkii，在找一些老版的K240玩玩。

如果在這Fostex T20RPmkII、K701和K712pro之中選，我會選這Fostex T20RP mkII。K701和K712pro會是更hifi，聲音分離度、辨識力好點，但聲音覺得有點“假”，尤其人聲欠了點味道。再看價格，這Fostex T20RPmkII才7千多yen，抵玩好玩好聽。

Hi Ericcho,

Thanks for your kind advice.

My T20RP mkII arrived today, and just tested without serious run-in. I second your opinion and found out the T20RP mkII (without modification yet, and the sound still very natural and smooth) is a wonderful headphone at such low price.

In comparison with Alessandro (MS I), AKG K142HD (old version, made in Austria) and K712Pro. Those are good HPs with different timbre.

For HiFi parameters, K712 is the best but not good for big scale orchestra works. My favorte all rounder HPs are T20RPmkII and K142HD.

Considering to have basic modification after times of listening.
