I haven't tried it, but You can buy stamps with any logo. They laser etch a rubber sheet for those. Using that rubber sheet and a proper paint would be my best bet.

Removing a speaker from the faceplate is always risky. If You do not need the faceplate anymore, then it is better to cut it into pieces, and remove it that way.

Nice illustration. We can also see twisting the tunnel also longer the pipe air passes trough. But does it change the sound? In standard definition that changes the tuning frequency of the port.

Not yet, but I have saved them if I can make something with them. It is so ridiculously big! :smile:

If You measure the line resistance with a multimeter, it is 75Ohm, not 150. I believe the left and righ speaker is connected parallel. So Nokia phones do not have to drive 150 Ohm, they see 75 Ohm. If it is the case, then it is not stereo. It says "dual headset" on the package too.

Red is the red, right? I wander on the lower end. The PK shell should be more different than a bell shaped shell, at least I would expect that.

So, then tell us how you like it when it arrives. :ksc75smile:

Try heating it, the glue may get more flexible. Then this is my preferred tool. It can be found in kitchen drawers, bars and pubs: This is how to use it on buds: The firs tool is best for PK shells but it depends how it grabs the cover.

Why did You choose that if You feel the graph is weird? Titaniums have better treble extension than the fibre/wool variant, but the diaphragm material is thick, heavy. So Yes, I would also expect it to have more low end. Also a tuning foam is goint to help on the back of the driver. But that dip...

I had bad luck too with removing covers, so last time when I wanted to remove an original I sacrificed it by cutting up the side to 2mm pieces and peeled it off. It is better than a broken driver.

I will think about it. :hourglass_flowing_sand:

Yes, it looks good. Did You make them? How hard is it to pull the cable trough? Does it have a special technic?

I am looking for paracord / fabric / textile cable, that looks like this: I could take apart a cheap earphone but the jack is not even plated, and the cable itself looks very thin. So far I haven't found it on Ali.

It's a beast! Isn't the cable too stiff? Does it stay in thee ear easily?

I am smiling every time!:ksc75smile:
