100+ Head-Fier
If you don’t get the felt, I would suggest putting the phones on and taking them off very slowly to avoid abrupt pressure changes. I would also avoid moving them around a lot or pushing in on the housing once they’re on your head. I recall the LCD4 without the felt creating a very tight seal which will transfer any movements to the diaphragm.
Yep I've already learned to do that pretty early. The first time I put on the LCD-4s, I put them on fast, and heard the vacuum seal shifting the diaphragm around. Sounds kind of like paper crinkling. But if I take off and put on the headphones slowly, I don't hear anything. It's almost comical how slow I take them off now, compared to my LCD-3 and previous Audeze headphones...though I probably should have been more gentle with those too.
