White noise seems a little better than the Penrose but it really depends on your sidetone level. Muting the mic doesn't disable sidetone oddly enough.

Pretty sure it's due to the planar magnetic drivers: Audeze Started happening to me today and I've had my pair for a month or so. Hopefully it goes away on its own...

You sure about that? All other data points indicate the Penrose mic is a significant improvement over the Mobius mic.

Just wanted to chime in and say I found out about these the same way. I have a different use case (PC gaming + conference calls) and I’m likely going to keep them assuming the firmware update is the magical mic fix but wow, that subreddit is ridiculous. Audeze, you should be paying that...
