It's a little daunting, is there one that is gaurenteed to give good results whilst not being  very hard?

Thanks again.
 

While yes, some users have placed other materials on the ear side of the baffle, it has typically been done for a few reasons.

 

1) It was explained the the orrthodynamic drivers are bi-polar (I believe) and need damping on both sides of the baffle.

 

2) Others have placed materials on the ear side of the baffle to bump out or raise the ear pads to  provide a better seal or slightly raise the pads on one side or another to fit their own person head shape better.

 

Normally, when it comes to applying the modifications, I'd suggest sticking with the 4 or so basic mods that are performed inside the headphones first - as those items are proven and tend to provide the best increase in performance from the headphones themselves.  The other enhancements should probably be done one at a time so  you can determine the value of the modification.  Granted, these mods cost very little to purchase the materials, so really it's just your time that is spent.  However, doing this smaller simple mods as "extras" will possibly provide big improvements for some  users and lesser improvement levels for others.  It all depends on many variables.

What would the 4 basic mods be? I planned to do the sennheiser HD215 comfort mod ($20 headband glued to the inside of the fostex headband for added comfort) and the pads I'm not quite set on yet, I'll probably go for the DT-990 velours or possibly the gels if I feel the extra seal might be warranted.


It's tinkering inside that scares me, I also have no idea what to buy either when it comes to felt/clay or what have you, if I do end up doing this which from the way things are going it's very likely, I'll definitely grab my video camera and make a full length video of me doing all the "basic" mods, it'll definitely prove useful for those like me (I wish I had a video to go by!) who are very new to this.

I choose to see the Fostex/O2 as dropping my average cost, lol

The modifications are described in the threads and posts here.  If there is some form of intimidation with opening the cups up and going forward with the changes, you might want to commission someone to apply the mods for you.  The mods that get performed internally are some of the most important aspects of this whole process.  The external mods can be for comfort, as well as adding a bit more bass through the use of pad spacers or even different pads.  However, it's the meat inside that provides 80 - 90% of the change that gets applied to the sound.

Quite true.  But, after being accustomed to opening the wallet far and wide for most of the good sound we desired in the past, it's hard to imagine what we're getting for such little cost here.  That's the part that amazes me.  If one cam be happy with a pair of $80 headphones with $20 in modifications and an amp that costs $130 - assembled, then great sound has a better chance at reaching more of the masses - rather than pushing them away due to the extensive costs that could quickly add up by taking other paths.

It is nice to have something like this where I spent around $200 and it comes quite close to my other headphones where they all cost a good amount more. I always like bang for your buck kind of headphones :) However I wouldn't want them as my only pair of headphones so I still fall under those that spent a lot of money for headphones

After long time experiment with modding from BMF ver to Rp2 840 ver and my own customization, my pair just sound decent, nothing special. I let some of my friends hear it who is also into headphone hobby and it fail everytime to impress them. I don't know what's wrong? I'm using it with the Millet Starving Student which Smeggy also have and i think it's good enough. I opened my pairs a couple of time reading carefully the modding tutorial and see nothing wrong about it. In fact i have lost my confidence, now i even don't beleive the t50rp modded can compete with the HD650. May be there's something wrong with my equipment or my headphone or my ears, my friend we soon send me his t50rp, i will see how does it sound compare to mine.

I'm not sure about the 4 basic ones, but I think the following would summarize the basic mods.

You're a legend, I was also interested in doing some T50RP modding.

Can you list your mods?

I've found the Paxmate here which is fantastic as the left-over will be put to great use on my computer.

But I'm unable to find any plasticine in the UK, the only stuff I can is children's toy plasticine.

And for the last "core" mod I heard I'd need some felt however it seems there's a lot of felt and people have had trouble in the past finding the right stuff, any link (preferably to a UK vendor) of the correct felt I need?

 

Then with the plasticine/paxmate and felt modding done I believe that's the last of the primary mods, then I can add my choosing of pads and I'm away!

Also, this may seem like a silly question, but I've seen pictures of people adding something under the pads, any ideas what this might be?

I bought a pair of these last Spring with high hopes. I found them to have unacceptably "subdued" highs and low bass. I attempted to burn them in hoping they would get better to no avail. Certainly not anything that could be trusted as an accurate reference. The only thing I can think is that people like these who have either never heard better headphones or simply love the midrange to the exclusion of the highs and lows. I have, have owned, or have auditioned most of the better headphones out there. I currently own the Sennheiser 650s, AKG 701s, AT M-50s and the Denon 2000s, 5000s, and 7000s, wthe 7000s being my favorites by far, although not perfect. I use them in a studio context and have excellent full range speakers and amplifier that are not overly bright. Sorry for the wet blanket but for me, the Fostex were a waste of money.

This is my current mod:

-plasticine back of the baffle

-dynamat back of the cup

-paxmate plus over dynamat

-driver white felt remove

-1.5 layer of transpore 

-bass vent remove

-3.75  bass vent closed with paxmate

-cotton ball teased inside the cup

-dynamat then paxmate ear side baffle

-earside felt remove

-shure 840 pads with cotton lifter

I tried Rp2 840 and BMF 6 before, the transpore tape ver sounds best to me.

I think there are at least 10 different times where people have said they aren't worth listening to stock but with a few mods go to a whole new level. Some have modded them to rival or even beat the Denons you mentioned. So no wet blanket, you just need to go through this thread better and see what's going on behind the scenes.

Sorry for the long delay to respond. I had to try to remember what mods I made to my T50RPs! First off, I am not sure I would waste my money on the Fischer FA-003 at this point, as, for me at least, the T50RP can be modified to far exceed the Fischer's capabilities. Stock though, the FA-003's are far better, IMO. They are actually quite good phones for some types of music, but I find the sound stage to be pretty constrictive, and the overall sound of properly modified T50RP's significantly outpaces them in all major areas I can think of (lows, mids, highs, soundstage, overall believability). The pads are nice, though...

 

Now, as far as the T50RP's, mine are a modified version of the Rastapants 2 840 that Mr. Speakers has so kindly put together. I used original Dynamat to line just the backs of the cups, which are then covered with Paxmate. I believe the center pillar thing is covered with Paxmate as well. The baffles are covered with Plasticine that is fairly heavy and tapered out to the edges. I have removed the white covering on the driver back and am using an electrical tape reflex dot on the cenrer square. I have about 2 cotton balls teased inside the cups. I did not seal the cup seams at all. Finally, I believe I have the original black felt over the 4 baffle strips on the inside, and I think they are all still open (no electrical tape to block them off). On the ear side of the driver, I left the felt in place and covered it with a layer of original dynamat and a layer of Paxmate. I have cut out the black felt over the driver, and I use Shure 840 pads with a rolled up gauze pad to wedge the back of the pads.

 

Finally, keep in mind that the AKG K501 really needs good amplification to shine IMO. I am extremely happy with the overall sound of my pair, although the thing I like about the T50RP's compared to them is the greater weight they give to instruments, particularly electronic instruments. For classical music, from chamber to large scale, I prefer the K501's. For rock, pop, etc., I prefer the Fostex's.
 

 



No problem at all, and thanks for the information. smily_headphones1.gif

 

I agree with you, there aren't many that can beat the K501 in the size of the sound stage and the airiness. I am not much of a classical listener but I like it for everything involving vocal and acoustic instrument.

 

And one less thing to buy is always good news for me. biggrin.gif
