I sure don't want to get in a p*ssing contest here, but I've been using
a Bose headset for a couple of years now and love it.

I also have a Lightspeed 25XL and it's a great headset, but the
clamping force is much greater than the Bose. When I fly with my wife
the first thing she does is grab the Bose. :)

I carry six spare AA's in my flight bag, as backup for the headsets and
my Lowrance Airmap 1000, and my Icom handheld. My flashlight uses AAA's
and I have two extras.

And, I'm currently flying a Warrior. It doesn't need any batteries.
Just gas and oil. :)

The cell phone interface is one thing I'd like to have. I've never had
any real use for it, but I always thought it would be a nice backup
item.

Ok, reality check. The Bose (as the DC) has auto-shutoff when not worn.
The batteries will last, what, 30 hours? You fly how many per year?
Let's say you need three sets per year, maybe five. That's "lots"? And
there'S a warning light before they run out.

4 AA for AM 2000.

4 AA for flashlights

4 AA for 2 ANR headsets, (2 B announced)

4 for spare GPS

4 AA for portable VHF

2 AA for CO detector.....

Etc..

Batts are only one part of the failure possibilities

Local Bose have needed service several times...

No dealer has offered the Sennheiser for test, and the local
experience with Lightspeed is not good. Work as advertised, but
spend far too much time on FedEX aircraft.. to and from service...

Ah, the magic of marketing...

No... lot of comments by posters here and on the Cherokee groups...

MANY posts about the great service of the Lightspeed guys, - and the
need for it...
