Dan,
 
Based on all your time spent modding so many pairs of Fostex, have you seen evidence of sound quality being vastly different between different pairs of T50RPs?

In my experience, driver mismatch has a strong effect on the perception of sound quality. Possibly moreso than overall frequency response (within reason).

Yes.  We have a target sound/response, the majority of units are right there first pass, but some take quite a few passes to make the curve, and a some never do.  Channel mismatch isn't too common once you rule out the easily cleaned oxidation on the cables...

Yeah.  That's much harder to address than a phone that's more or less efficient than usual but otherwise has a similar response.

Hey there Speakers. Have you ever thought of creating a plug with two slots to insert resistors into? It would be a cheap enough item to create and being able to play with impedence would most likely prove irresistable to the community.

 
Maybe sometime...  Irresistorable is hard to resist.

Now that's almost sounding like a product name

hey guys i'm planning to get a pair of t50rp's and was wondering how should I mod it. My budget is only 200USD including the headphones so i'm getting them from ebay for about 140USD including shipping to my country Malaysia. So I have leeway of 60USD to do mods any suggestions?

The biggest (and most costly) change is slapping some Shure 840 pads on there. After that, cotton balls or other random stuff to put in the cups, but really the pads make the biggest difference. That mostly brings the bass balance up (as well as better comfort). The rest is mostly fine tuning.

On top of that if you can get some audio dampening foam (paxmate) and some clay (plasticine) to stuff into the cups that will help as well.  I think out of all the modding materials excluding the pads the dynamat and the paxmate is going to be the most expensive.  You can get a small amount of dynamat though at a local car shop that puts speakers into cars.  other then that everything else is very cheap and easily found at a crafts store.  As for what mod to do.  If you have all the stuff just have some fun and try different ones out and see which one sounds the best to you.  Happy modding

alright thanks guys from the graphs i've seen from the incremental mods I think the rock wool+840 pads seem to make a good combo. Less rolled off bass and highs.

 

[Zashoomin]

Well here check this out this has a lot of different mods you can check out.  http://www.head-fi.org/a/fostex-t50rp-modification-summary-links-wiki  Out of all of them I would suggest you look at bluemonkeyflyer's mods.  (BMF)

So uh.. I might be getting a job at a car upholstery place. Keep your eyes open for some custom pads by me.. I'm likely to make some headbands too

For me the next step in the modding process was always creating new pads. The Shure's are an improvement on stock.. but I feel they really hold the headphone back overall. Especially when it comes to the midrange.

My idea is a relatively flat pad, with no large open areas for the pads to "echo" and otherwise screw with the sound. Anybody know of any headphones that come with a pad like this? Picture a flat donut for an idea of what I'm thinking.. Or maybe even something kind of like a grado Bowl. Maybe I'll draw some pictures.

 

[Armaegis]

Flat donut?... random ones that come to mind: AKG K181, Pioneer HDJ-1500

 

[Zashoomin]

I am thinking more like and Audeze pad?  Even though those are really angled.  But if they didn't have that angle they would be donut shapped. 

 

[jgray91]

How would that work for comfort though? On the other hand, looking at your face, I can see how you could be comfortable, as your ears doesn't seem to pop out much.

As for flat donut pads... Nothing came to mind..
