Jay,

This may be old news, I have the 25XL after three separate problems with
20XLs - complete loss of ANR, no ANR in left ear, battery discharge to zero
in 5 days even with no use. Lightspeed service excellent.

25XLs robust? don't know - haven't been flying much lately so time will
tell.

OTOH had the DC H20-10s passive - loved them, but couldn't afford the DC ANR
version and DC Had no trade-up option. My only alternative was to do the
do-it-yourself Headsets Inc upgrade, but this was same cost as selling the
DC20-10s and buying the 20XLs AND voiding the DC warranty and service etc.

I found the DC20-10s robust and comfortable even after a few hours, so that
wouldn't be an issue for me - Cannot comment on the standard David Clamps -
haven't used them.

In a nutshell - Lightspeed very comfortable, but not sure of robustness -
DC - pick the right model and you might find they are also comfortable (and
aslo built like the proverbia Brick sh#$%^t house). Regardless, wouldn't go
back to passive unless no other alternative.

Cheers,
Kevin

Absolutely. How long since you've seen a thread on Davey Clark repair
services?

Trouble is, they're made so strong that they weigh a ton, and hurt my
head.
