Audeze headband of your choice, a set of the audeze yokes and dremel or file. All you need to do is take out the stock headband and yokes, then widen the holes enough on the audeze yokes so that you can fit the monolith pins into the audeze holes.

However, here are a few other things I would add. You could Dremel out the holes to match the holes of the M1570 headband, but that was more work than I was wanting to put in.

So, what I did was just used a 5 mm drill bit, which gives a fairly snug fit. (The set I used is available HERE) Also, a 0.9 mm hex key is needed to remove the screws holding in the pins to the yokes as well.

Also, another thing I have not seen mentioned before is you will also need to remove the stop pin on the yokes as well. I did this with a pair of side cutters, and then filed it down till smooth.

Another thing to note about the yokes is that the short side of the yoke goes towards the front of the headphone and the screw tab needs to be pointed towards the outside of the headphone.

Also, just for clarification on the rods, the philips head screw goes into the toothed washer, through the screw tab on the yoke, and into the completely round end of the rod. The flattened end on the rod is what actually go through the headband, and then the slotted screw goes on the top end of the rod. (HERE is a pretty decent video showing this)

One more quick clarification, here are the 4 screws that you have to remove to get the driver out to reach the yoke pins.

Here’s my final product…

Wow! This really does feel and sound great! And I totally agree with @dxccal, the increased clamp does improve the seal which increases the punch and dynamics. It also greatly improved the comfort too.

I’m not sure if it’s placebo, but it sounds better, maybe it’s the better clamping?!

Also, just for completeness, here are some good guides by @dxccal and @juicebox12 as well…

It has begun, removing the m1570 cups from the headband is easy. Removing the driver’s from the housing reveals a foam pad behind the grill. To remove yolk from the cups you have to remove two small pins one on each side of the cup. The hardest part is getting the audeze yolk to fit the m1570 outside pins, that requires drilling and some jb weld. Will post final assembled headphone when glue is finished drying. Wish me luck.

I think it increased the bass a fair amount but it’s hard to know for certain without a stock set to ab. The mod for mine was very simple. I simply elongated the yoke holes vertically using a dremel and small stone. After that I was able to re use the stock pivot pins off the stock yokes. Very simple mod and allows the factory stops using the pin with dowel. I really wish I took post dremel photos but I kinda just did them one at a time and worked at them till the pins were a snug fit. Overall mod took about 45 minutes to complete.

The overall fit is much nicer for me. The contact patch is the whole leather strap essentially. The clamp force is actually a little stronger then I would like but it’s not uncomfortable.
