I've not heard this popping sound, Blanche. I hope it's not your engine!

However, this does illustrate an issue I've always found funny, which is:
People who say they "Don't want ANR headsets because they want to really
*hear* the engine..."

What a load of malarkey, eh? You can hear the engine -- and anything else
going on in the plane -- 10,000 times better using ANR headsets, than
without them.

Heck, I've got a rattle that drives me NUTS at 23 squared. It's the
co-pilot's ashtray cover vibrating.

Try to hear THAT without ANR!

Jay:

I just got a pair of the twenty3G and most of the time really love
them. Unfortunately, I now hear things I didn't before (I've been
using 15Ks) which makes me a bit unsettled -- the A&P and I are going
to do research on my engine...

One issue -- a popping sound as I'm taxiing and during takeoff. Don't
hear it again, but every flight so far, popping.

There's also a whine once in a while which I think is the final approach
of the ILS but it's been happening in other locations.

Once it warms up around here, I'll go do more study.
