FWIW...if any of you are flying with a Bose in cold weather and are tired of having rock-solid ear seals each time you put on your headset or helmet, I finally found a company that sells replacement earseals that are not made of memory foam.  These are made from regular high-density foam and they remain soft in cold temps.  Yes, I know...#firstworldproblems

They were rather inexpensive ($15), and was a bit of a struggle to install...but I did get them on eventually.  We'll see how long they last.

I use a standard A20 Bose in Alaska. As soon as I sit down, I clamp the headset to my thigh while I strap in and do my cockpit check. One or two minutes is plenty of time to warm it up enough to wear. 

That worked for me a while back.

Bose a ew times.  Like having a huge dish rag on either side of my head.  Lots of pilots love them.  Bottom line is protect your hearing at all cost.
