marketing trick? or the inclusion of a lower voltage-rated part?  i think the former ..

Stax earpads for SR007 Omega II earspeakers. It seems the Brown ones are 40 dollaes cheaper than the black ones confused_face(1).gif

 

I'll probably get them at some point. I know I can effect the sound of my Grado's quite a bit depending on which pads I use; and I plan on probably doing the Thunderpants mod at some point. I'll try the felt when I open them up and trade out the blue tack with some plasticine. Maybe not I'll probably just want to try and discern what the plasticine does first. At any rate I'll probably have these things open a few more times.

 

 


The black are a very nice kid leather. My understanding is the brown are synthetic.

I have a set of the black and they are incredibly comfy. They sound and feel better than the 840 on the t50 cups, but since they cost so much more, most people probably will be better off with the 840 pads..

But the o2 pads are round and the 840 pads are oval, exactly how do the round pads fit?

post #1984 of 10623
The O2 pads have a round former built in and a wide gasket so they actually fit easily and very snuggly, with no weird warping.

Since I'm a big fan of DIY, I'm thinking about picking up a pair of these and modding them

 

However I'm looking for more of a "one stop shopping experience" when I pick up modding materials and I'm seeing a lot of talks about buying paxmate and acoustic foam and such. If I go to the crafts store to pick up plasticine/modeling clay, are there any other worthy alternatives at a B&M store instead of ordering paxmate,etc online?

 

Thanks!

Nope.  The best you could probably do is get another modder to put some stuff together for you.

 

Dynamat can only really be found at automotive stereo stores, Paxmate is a computer damping foam, and most of the other stuff is found at a fabric store.  You probably have minimum 3-4 stops (for glue, etc. as well).

Thanks, I'm assuming there is a little more soundstage with these too?

 

Anyway I've made it up to and through  90 pages now, and I've had my cups open a couple of more times. I switched out the blue tack for plasticine a couple of days ago. Today I lined my cups with some paxmate thanks to Chrisangley and put a piece of felt over the driver. They sound good but the right cup seems like it has an echo in it. They are much different than my Grado's, which at this point I still prefer, but there is something very compelling about the presentation of these things.

 

post #1988 of 10623

Try paxmate on the ear-side of the baffle surrounding the driver, and removing the felt over the driver.  Also, changing the ear pads to the 840 or O2 and then restrict the port to a very small (5-10% of the surface area) hole to tune the bass and they will rock.

Has anyone tried fitting the SRH840 pads to a round cup, 100mm or there abouts?

post #1990 of 10623

Hey Now,

 

I screwed up and pulled the solder pads off one of my drivers. frown.gif I know. . . .Sensitive little buggers.  Anyone else do the same and gave up on modding? . . . . if so, want to drag out that perfectly good single driver and sell it to me? Let me know.

Hey Now,

I currently have the SRH840 pads on my T40v.1, they fit and sound nice enough.

It is possible this is just a marketing moment, but also, in loudspeakers that are closed box, driver excursion increases compared to ported enclosures due to the back pressure created by the port.

I was thinking about this and the physics of the vent aren't quite the same, nonetheless it may simply be a limit on the driver excursion, or as a less likely scenario heat buildup in the closed enclosure.
post #1994 of 10623

I seriously doubt there is heat buildup.  Fostex doesn't seem like the kind of company that would falsify technical data to upsell to a headphone worth $10 more, though.

post #1995 of 10623

They might be physically identical and yet run different drivers grade(even for the 50, some have either a red or a blue marker dot on them), it doesn't seem wise to go 40 in order to save a few bucks.
