I was really nervous performing the mod since I’m typically rather klutzy and the HP-1 has that polarity switch so there’s a lot more wires in that cup that need to be moved out of the way to secure the foam (4 wires from the center of the cup to the driver plus the two wires entering the cup to the switch backplate). I was paranoid that some 20 year old soldering joint would snap as I moved the wires out of the way... but I got through it unscathed and the end result was worth it. (I’m still too nervous to try the dynamat mods to the back of the driver. But I think I like the existing bass impact too much to add the damping, anyway)
Yeah, earlier in this post I clumsily torn the cable to the left driver... grr. OH AND that was my HP2! Props to you, I'm looking at the rat nest that is inside my HP1 right now and I can't even conceive how you managed to do this. I think it's a neat feat really, as there is no room to operate at all in there!
I have a stock HP1 and a HP2i, let's meet and A/B the crap out of those headphones... can I go at your house? Seriously you got me curious about Purrin's mod... and no, I will not apply it to my HP1 :(.
I’m gonna stick some leftover foam on the pads. brb
edit: I did it. OMG 400% more detail!
ok, but seriously, I think I would need more than 1 mm to notice a difference. Maybe splitting the difference between the bowl and flat thicknesses
You mention volume and that’s actually something that concerns me. It’s way too easy to crank the volume up with these headphones now. I gotta be careful if listening for a long time!
Improved flat pads are about 1-2 mm thicker, yeah. The same ones that really provide 400% more detail "OUTPUT".
Any of you can give me their feedback on my custom pads:
Basically you put on a HD414 pad (no absolute need to be quarter-modded but it's a bit better) and stick a bowl between it and your ears (I double-side Scotch taped the two together but you can manually fit the bowl easily, for trying purpose and quick revert to normal).
They do just that, open the sound stage, remove some bass presence, adjust the highs a bit. At first you might think it's lacking in bass but I assure you that it's still fully there, just compress the two pads a little bit. I came up with that while wanting to use bowls without my ears to touch the driver walls. Comfort is great, but the pads require breaking in for the HD414 to flex and for the bowls to memorize your circumaural head topology.
