I have some rechargable wireless headphones that I use on the
treadmill. The NiCads have developed so much memory that they only
last about 1/2 hour.
Can I replace them with NiMH? Will the charging dock handle them the
same?

Your headphones will probably work fine with NiMH, BUT YOU MUST USE A
DIFFERENT CHARGER, ONE MEANT FOR NIMH.
I repeat, do not charge NiMH batteries in a NiCad charger.

Yes, it should work fine. I use NiMH cells on everything I have that
takes NiCads, including my expensive Canon 550-EX flashgun.

That's a different story. If it trickle charges (eg; 12+ hours on
NiCad cells), it should be fine. If it uses a fast-charge system, it
might be okay, but you're tempting fate. Just go & spend $20 on a
generic NiMH fast charger.

Almost invariably they're fine.

Because that will ruin the NiMH battery and may smoke up your
workshop. OMU

I've had NiMH on a NiCd charger (NiMH/NiCD switchable) for somewhere
around 15 minutes once. While the batteries appear to have survied
without incident, they did get really hot. It makes me wonder if they
could explode. (Heat --> pressure --> POW!)
