Well, my 2-day old PH's have received a ZMF Comfort Strap and ZMF Omni Lambskin pads. The comfort is stellar, they are now like pillows on my head! My X00 pads will now transition to my T50RP Mk3's
Did the sound change with the pads? I'm not well equipped to answer that, as I've only had about 6 hours of listening time and the sound should still be changing slightly anyway with burn-in. That being said, my gut tells me the sound remained unchanged. But I don't guarantee it.
Comfort is now amazing, but clamp is still too light. They tumbled off my head on the first day when I went to swallow my daily vitamins. I will work on the headband gradually to try to correct this.
I have a Lawton kit sitting here that I'll install next week after I'm more familiar with the stock sound. After that I'll further tune them with the EZ Mods....rotating the foam ring, etc.
I am extremely happy with my X00's! Thanks to this community, they sound EXACTLY as I imagined they would, based on community perceptions.
My Stax still get the nod on overall musical fidelity, but it is a little closer than I expected. X00 will be an excellent basshead can to pair with my neutral-ish Stax
