I'd really appreciate it if any D5000 owners can take pictures of their drivers or tell what's stamped on them so we can definitively know if they are the same. However, comparing the pictures in the first post to what I've seen in the D2000, both drivers look very similar.

Left driver:



Right driver:




It is fortunate that the number is still on the driver. This should make the question much easier to answer.

Now to find a revealing picture of the D5000 driver

I checked my D2000, and yes, the number on the driver is the same; 439360 (no great surprise).

Here is the comparison of the drivers as previously posted by zmorris. The drivers appear to be identical from this spec sheet, but I guess we'll just wait for some kind soul to post the number off the D5000 driver.

This is interesting. I had originally thought that the black piece with all the holes in it in your D5000 pictures was injected molded plastic, similar to what's in the D2000. At least it looks that way.


Let me verify this the next time I get another pair, you may be right. However, in person the D5000s outer ring seems to be made of sturdier stuff than the D2000's.

Has anyone figured a simple / effective means to tighten up the "axles / spindles" which connect the metal driver housing assembly to the headband assembly (i.e. the two connections on each side of the driver housing metal frame)???

Mine are slightly loose and vibrate slightly back and forth - just the standard fit to allow each to rotate freely in and out - but, ideally, it should fit more tightly on each side.

I don't know what would work - perhaps, some type of "shims" (e.g. tape, or tin foil, or even wood or plastic shims - to tighten the fit to prevent any vibration)???

Any ideas - successes???

Check page 22.

Quick question: From pictures I've seen (namely the step which you are meant to add the incredibly thin layer of fiberfill), the D5000 wooden cup is solid (hence providing a layer which you can place the fiberfill on), while the D2000 looks hollow with that piece of foam that the stock phones are meant to come with. Is this correct, or is the D5000 wooden cup hollow as well?

EDIT: Oh I see. You are meant to make the cup "solid" using the Dynamat.

Thanks for your help... but... all I could find on page 22/23 was how to tighten the fit of the screws in their holes.

I see no discussion of how to tighten the fit of each phone housing on the two spindles / axles / whatever that connect each phone housing (both the right and the left - four spindles / axles) to the headband.

There are little white plastic / nylon washers or shims located in the joint around each spindle / axle, but they're still somewhat loose and vibrate a bit, rather than fit snuggly.

Same here. I guess I'll get MD5000's + APS V3 and sell my D2000's.

I specifically wrote about this problem and provided a solution for it on page 22 (also a picture on page 23), yet you seem to be glancing over it for some odd reason. Here, I'll help you:

You won't be able to remove the c-shaped washer that holds everything together to add more washers to tighten the fit, but adding thick grease like Arctic Silver 5 will tighten the fit and eliminate the rattling noise.

OK... thanks for the info... but...

... if you'll review pages 22/23... you'll find there is nothing addressing this issue.

Perhaps it was on an earlier page...

I meant check page 22 of this thread, not the forum/subforum, which should have been pretty obvious. Regardless, I've already given you the solution in my previous reply.
