^ someones a little angry.....,
Anyways the original headphones are 70 ohms.
The other drivers were spare parts, so usuming that you have a small set of junky headphones that you don't care about you use those drivers, really any driver doesnt matter, just needs to fit.
Parrallel, i thought that was kinda obvious.
And an amp really isn't nessacary but i dont see why you wouldnt want to

I'd be assuming that the Earbuds that were used have anywhere from 16-32 ohms, no more thatn 32.

I got an idea! Does anyone have a clue what effect drilling holes in the cups of my closed über-cheapo HP200's would make? Would it make them better or worse? Is it worth trying?

Thats exactly what im now doing with these. Im drilling 1/16 holes to try and get a more airy sound, all update the thread after im done, there are a lot of holes to drill.......
All tell you how it works.

But knowing what sort of amplification you are working with will help determine what they can be run on. But since we don't know the impedance of both sets of headphones, you could now have 70-Ohm + 32-Ohm or maybe 70-Ohm + 300-Ohm.

I do not use an amp with them, and i think its reasonable to assume that Philips headphones from a CD player that was bought in 1996 for 30 dollars does not run 300 ohms.
whats your obsession with this this thread anyways?

Sir, you have to be using some sort of amplification or you could not use your headphones at all.

Umm... I don't know. When I first saw the thread title I thought, "Oh sweet, everyone wants to get relatively good sound from relatively cheap headphones, am I right?" But instead it was a "hay guys i installed x drivers in tandem with y drivers and got z result" and is splintering into other interesting directions. I think the thread has potential, but I misinterpreted the title and was consequently disappointed. No matter.

Keep modding! Sorry for the drama.

The holes did make an improvement, they are a lot less congested and sound more airy.

 

[Lpe_91]

Now that i've drilled holes in my cheapo-HP200's i can confirm that it DOES make an improvement to the cans, the highs get a little boost and the bass less boomy.

Are the pads on these thick enough to keep the grill off of your ear? I always wanted to remove the grill from in front of the drivers on mine, but the pads are not thick enough to allow this. I'm afraid my ears would hit the drivers.

 

[XGJFilmsX]

the pading is thick enough to keep your ears from hitting the supporting struts that you can see in the 3rd picture that are protecting the driver.
