Stax ear phone pad

I doubt that is an issue, Mark. The foam is just there to protect the electrostatic element, and looks to be sonically transparent (at least on my older Lambda Pros). Also, a few years ago the foam on my Lambda Pros partially disintegrated (after about two decades), and I didn't notice any sonic difference as that occurred.

Eventually I replaced the pads and the foam together, with a replacement kit purchased from Audio Cubes II. In case it becomes relevant in the future, I believe (although I'm not totally certain) that the replacement pads they offer for your newly acquired SR-404 come with replacements for the foam as well, and both are installed simultaneously.

Almarg is right, that foam piece is unnecessary and you can easily remove it without any problem. I'm sure you realize that the SRM-006T is the driver unit, not the phones. Don't let that loose foam bother you, just plug in the phones and congratulate yourself on your purchase. I predict that they will be with you for a very long time.

Tonykay, thanks for bringing that to my attention. The headphones are the SR-404's. I see I messed up the heading too, should have said foam, not pad.
Looking forward to setting this up and listening.
