Just listened to some Fostex T50RPs today... WOW! - Page 617

I have tried different sources, flipping the headphones around on my head, listening to mono sources, etc. At times I come away convinced that what I'm hearing is just in my head but more often than not I come away convinced there is a channel imbalance. Tonight I decided that there is absolutely an imbalance. Right now I am listening with the right side balace ~ +2.5 on my vintage Nikko reciever.... things sound MUCH better.

I have opened up the headphones multiple times to examine the mods (roughly the latest BMF) to make sure things are done correctly and symmetrically and everything seems to be perfectly fine. The only thing I can think of is that the internal wiring is poor or something. I have a v-moda cable so I know it's not that. Does anyone have any suggestions? This is actually driving me crazy...

The channel imbalance issue is easily solved by either spraying the jack with Deoxit, or replacing the cable with the V-moda Audio only cable. These two are the simplest, and perhaps cheapest solutions available.

 

Hope this helps.

You've done just about everything. In addition to trying De-Oxit, the only other suggestions I can think of include a hearing test and getting an SPL meter to test both sides with test tones. I would do the SPL test first. If you don't have one, PM me.

Anyone know if the Shure SRH840 pads that come with the headphones are differently sized from the replacement pads?  I tried to use the extra set that came with my SRH840's, but they just don't want to fit.  I was gentle as possible and still seemed pretty far away from getting them on until I snapped the thread that maintains the edge and unfortunately tore it.  Even now, it barely fits.  Don't see how it would have gone on intact.  I will probably use doublesided tape or glue once I have tuned the rest of it.

 

On the plus side, even just holding them on with compression, the bass response has increased.  Definitely boomier, but I like the presence.  And some very uneven cotton ball stuffing definitely brought out the treble.  Need to do a better job of pulling the cotton apart distributing it evenly.

Are you using the stock cables?

I submerged the two connectors of the stock cable into a solution of water + baking soda, and brushing & washing it off after a few minutes. Did the job for me. THAT is the cheapest way if you don't have deoxit lying around in the house.

Of course that applies if the cable leads are the ones causing the issues, as is often the case.

Replacement pads should technically be the same as the original ones, as we all bought Shure pads not 3rd party ones.

The 840 pads ARE smaller than the T50RP ones, and DOES require stretching. If you're rash with it you will rip it.

I posted instructions on easy pad stretching and fitting... it's been washed away in the post counts but you might be able to find it.

Though at this point perhaps it is pointless?

Somebody else complained about this elsewhere and was told to roll back the rubber thingies around the pad, put the pad in place and roll the thingies over the cup. Don't know if it works or not, but others seem to be getting these pads to fit.

 

It's what you do with your thingies that counts.  tongue.gif

Well, the SRH840 pads are both on, and they are both slightly torn, however, it is only a cosmetic blemish as they stay on without a problem so far and I will be securing them with glue or some tape once I am "done" tweaking.  If I can get these sounding on par with my HD650's, maybe I will treat myself to a new pair of pads to complete the transformation.  I only asked if they were different because a lot of the pictures posted have white thread instead of the black on mine.  Thanks guys.

if the srh840 pads fit on these then the NVX XPT100 angled pads must as well since I was able to switch the pads between those two models. Those are the most comfy pads I have

 

Although they're gigantic (about 2" deep at the fat part) so I'm sure they have unpredictable effects on sound sig

Oh...

Yeah I think most of us have ones with white thread. Though they did come in Shure packaging, so I'm assuming they're the real deal.

Where to order? :D

Kind of similar looking to the HM5 pads (straight cushion earpad I mean), but maybe fuller.

The SRH840 pads I used were the spares that came with my headphones when I bought them.  And I bought within the first week or two of their release so I was wondering if at some point they changed the pads like the HM5.  No matter.

 

Those angled pads look crazy. The headphones themselves look like HM5's so the flat pads are probably the same.

You can't say that and not tell us where you got them from! I wonder if they do those in velour....:)

 

To put my shure pads on(for bopth the 940 velour and 840 pleather) I folded the lip backwards on the pad, placed the pad next to the driver and them rolled the lip from the top of the driver near the headband over the cup moving down both sides at once.

soooooo where to buy those pads? come on tell us!

 

 

anyways, a very big thanks to kalbee for getting the v-moda cable sent to our country! 

 

 

 

im really sick right now, so im not 100% sure but i feel that using the vmoda cable gives more low-end body and soundstage gets abit wider when comparing it to the stock cable. also, midrage gets pushed back by a little bit.

keanex did a review of the NVX XPT100, comparing it to the Brainwavz HM5 that it resembles closely. He commented on the pads:

I want to make it clear that while the same accessories are included, NVX’s are built differently than the Brainwavz, especially in the pads. The stock flat leather pads are very comfortable, providing a very soft experience that allows the XPT100 to be worn for hours. NVX is calling their pads ComfortMax Cushions and while I don’t know what they’ve done differently than Brainwavz, but the pads are certainly softer and more comfortable. The second set of pads are angled and are a bit more cushioned pushing my ear out a bit further from the driver, these are a bit more stiff, more akin to the HM5 pads, but very comfortable as well. I’m not sure if the angled pads are changing the sound or not, if so it’s miniscule, but they do feel great to wear.

...

these pads are a step above the HM5 and are the softest leather pads I’ve used. I should also add that I’ve used the XPT100 on walks during the hot August days and never once thought my ears were too hot during the hour of walking. Everything here is quality.

According to the NVX website, these are protein leather pads, not cow or sheep, if that matters to anyone.  

post #9254 of 10597

I wonder what that means? Most leather, regardless of the source of the hides, is made up of a protein called collagen.

Just did a search online, and protein leather is not taken directly from animals.

Quote:
Protein leather is a functional material created by combining protein powder with special resin. The outstanding moisture absorption/desorption of protein powder alleviates uncomfortable stickiness.

So I guess it's synthetic but not vinyl?
