Just listened to some Fostex T50RPs today... WOW! - Page 410

wje, you can tell me what you think of mine.  I want all the crituqing I can get so I give you permission.  I am selling them for next to nothing so any imperfections I can fix the better and people shouldn't care spending basically nothing for them.  For the bass ports, I used a 3/16" and a 1/8" hole.  The 3/16" is pluggable but I left both open for maximum bass I thought.  Maybe there is too much leakage and the plug is meant to create more bass rather than the other way around?  If you have the source equipment to test this theory please do.  Because I still think it's the bass boost that made the bass on these sound like 2 solobaric 15" subwoofers.  I wish I could make them sound like that again.

Jchristian, you should be able to buy the 280 pad directly from sennheiser. 

• This item: Fostex T50RP Studio Headphones by Fostex $105.00
• Shure HPAEC840 Replacement Ear Cushions For SRH840 Headphones $17.99
• SilverStone 21-Inch x 15-Inch 4mm Thick 2-Piece Sound Dampening Acoustic EP0M Silent Foam SF01 (Black) $13.95

So I wonder if the price has gone up because demand has gone up from all the modding that is being done, including the Thunderpants group buy..?

I wanted to try other pads because I rip my SRH-840 pads while putting them back. Does the Hifiman easier to install?

I thought the pads were not as nice.  They were a bit harder, like the S5000, and like the 5000 pads, they really killed the bass for the Rastapants 2 design.

The vendor on Amazon sells the $105.00 headphones with free shipping - as, the order is fulfilled by Amazon.  However, the same vendor - TheMIDIstore, also sells on eBay for $99 - with free shipping.  I ordered a pair of the $105.00 headphones from Amazon yesterday (Friday) and opted for the one-day shipping because they claimed it would arrive today (Saturday) for $19.95.  Well, they were honest.  The headphones shipped out of Arizona and I received them by 11:00 a.m. this morning.  I'm quite sure Amazon lost their shirt on the deal with me because even with their "discounts" on shipping, Saturday deliveries by FedEx are not cheap by any means.

Also, SonicFiber has a 10% discount coupon.  Included with the pair that I purchased from them was a printed post card with a code on it with the discount  information.  I don't have the card in front of me right now, but I'll get it a bit later.  So, paying about $75.00 for the 'phones from SonicFiber is about as good as it gets for the time being.

This is the lowest price shipped I've seen that has them in stock. I put in a couple orders to different places in the past few days but all sold out and canceled my order. Sooo... just bought a pair from him. Debating which direction I want to go with them, weather it's the BMF, RP2 or Response. Hoping to get a set of F-003 pads (actually Lindy but they should be the same) in this coming week to put on them. I think I saw somewhere that they need to be sewn to some elastic to fit over, is this true? Anyone have pics of how they attached their F-003/Lindy/HM5 pads?

One good thing I've noticed about Full Compass is that they also stock some Fostex replacement parts.  New ear pads, replacement cables, etc. are offered. Granted, those are items that I wouldn't essentially need, but for the individual that's not into modding the Fostex, it's good to have a source for the replacement parts when the current ear pads wear out.

SonicFiber ships out of New Jersey and they use UPS Ground shipping.  They're quite reliable and apparently have an actual music brick and mortar store, too, in New Jersey.  If you pull up their Web site, they offer quite a few of the items available that they also offer on eBay.  I can't imagine being a continuous vendor on eBay with the way they soak people for the 10 - 11% in total fees and then when people pay with PayPal, it's another 3%+ more in fees.  The cost of doing business sure isn't cheap.

OK, so I'm a bit late.

Here's the oh-so simple mod to the Rastapants O2 pads, I'll call it RP2 O2 v1.2.  

Bottom line if you've already done the full mod, the change is no reflex dot, and the vent is shut 75%.  Rough, huh?

Here's the complete mod...

Outside:

1. O2 black pads (all leather).  OH so comfy!
2. Black felt around driver on the ear-side removed
3. Paxmate all around the driver on the ear-side

Inside:

1. White felt removed
2. Dynamat/fatmat tightly pressed into all of back cup with paxmate over that
3. Plasticine mass loaded baffle with paxmate over the plasticine where possible
   1. Remember to run a thin bead around the outer-ring of the driver baffle to create a bit of a seal…
   2. (next experiment: NO plasticine inside to increase volume, only a sheet or two of of dynamat "ear side," with some foam over it)
4. Vent 75% shut (3 slots closed)
5. 4-6 teased regular cotton balls to fill loosely (still want to try some other cotton wool variants but too lazy to procure them)

Check out the waterfall (posted earlier) and note the transient response, and note that above 2KHz, the output is down more than 40dB within less than 0.4ms, with no major ridges (below 2K is cluttered by room/ambient noise in my not very quiet test setup.  

The frequency response sounds spectrally very close to my JH16s, with a bit more life at the top, which is too say a bit more "oomph" at the bottom 2 octaves (not to be confused with bass-head thump...)

As I’ve said before, where these excel is not in having the flattest frequency response, but in the transient/time domain response and their solid low end and extended top.  They are super fast, huge soundstage, really clear and super extended.  Speed, sound stage and dark space between the notes are fantastic, with a bit more weight to the bass than the LCD-2.  The dark space and speed are indicated by the uber-fast falloff in the time domain.

Shpongle never sounded better.  

Next step I will try some more reversible mods to see what I can do to kill the resonances and increase the system transient response with the white felt in place.   

BTW, the null in the curve at 10K is just a standing wave in my crude test setup with this phone.  Every phone I measure shows this, with minor shift in frequency.

I have around £200 ($300) and was thinking about grabbing a pair and modding them, although this thread is absolutely astoundingly big and although there are a few useful wrap-ups (modding guide wrap-up) It's still very intimidating.

I'm brand new to modding and rather than spend my money on a finished pair of headphones the T50RPs really interest me, is there a sound mod that is guaranteed to give good results rather than being handed a collection of them? How do you get pads and bands onto the headphones, would simple superglue work? And last but not least, the backs of the T50RPs aren't the most aesthetically pleasing, is there somewhere to buy fitting wooden backs for them or is that a "make your own or get out" sort of deal? 

Thankyou  Looking forward to hearing something.

Does the SQ justify the price of woodied T50RP's like Thunderpants/Koda^2 compared to modded T50RP's with stock back? Are the any impressions/reviews/comparisons between them?

I don't want to spend $400 or $500 on some headphones if >$150 sound nearly as good. Maybe I'm barking up the wrong tree entirely, I've got some HD448's now and I just want something to bring my music to life really. Something that will build on the atmosphere a song inherently has, something that has a bit of oomph. mrspeakers comment about dark space between notes is enticing, have you thought of selling rastapants like other modders have with theirs? I know you have given out instructions, and modding it myself may be entertaining, just curious.

I can't answer all your questions but the pads question I will. I just put on the Shure pads; HPAEC840. These pads simple stretch around the fostex shell just like the stock pads do. I read that this is hard to do, I found it to be easy, like using spoons on a bike tire (without the spoons and in methodology only) use the fingers to hold on a section you've just put on, go to the next section, put on and clamp with a free finger. repeat till that last bit where it's tight; pull press wiggle into place: done, easy!

I guess I found it easy because I put Koss pads on an esp9.....that was a struggle my friend.

As for the "kit" I think smeggy does a Thunderpants that he sells. Jude reviewed it on the main page a while ago and it has it's own Megathread. gl hf
 

DeathDomo,

   I have a pair of these on route,should have them by Tuesday?

He is selling  them on e-bay for $199-

Here is his website:

      http://jschristian44headphonemods.webs.com/woodent50rpinformation.htm

Check out his Gallery.

The owner-Justin,is a great guy,a pleasure to deal with,I had a few dozen questions,he responded right away

Although Thunderpants work, look really beautiful...and I'm sure it is........they are costly.

If he modded my existing stock pair of T50's..it would have come to almost $700.00 with the better pads,+ shipping to & from.

I have a strong feeling ,I'll be more than pleased with Justins work.

Hope this info helps,

Mike

When you guys line the inside of the cups with paxmate/dynamat/felt, without further mods such as reflect dot, does it reduce the treble/air of the sound signature?

It doesn't reduce the treble, it enhances it.  I never used a reflex dot on my stock modded.  I just used the clay on the back of the baffle and acoustic foam on the inside.  Of course I never did test them out stock, but I doubt it will reduce the air and treble at all.  I might not be the best to answer this I guess.  I just know that stock is pretty bad in like rattling.  It's probably like a car audio system with all your trunk metal pieces rattling ,etc.  Sorry!
