The "suction cup" effect is still there. This for me is probably even bigger issue. My ears feel really uncomfortable wearing these. I feel pressure (even slight pain) in my ears after wearing and listening these for a while. I don´t notice this effect with any other headphones I own or have owned/tried and that headphone list is a long one. Even the LCD-2s don´t have this effect. I told Audeze about this, but their response was:
"The "suction effect" you are referring to will occur with any open backed headphone. The ear pads have nothing to do with this. This effect is normal with open backed headphones."
I have to respectfully disagree.
Never tried the LCD-3, but my LCD-2 Rev. 2. have NEVER had a suction effect and I've had them over four months. The closest thing is a little sticky when it's really hot in here but that's only when taking them off; it's not felt when listening to the music.
