OK ! We did the Bose / Dave Clark flight!

Aircraft is a 1976 Warrior, PA 28-151

Stock, with new Airtex delux interior, 1/4 in windshields, 1/8 side
windows....

OK .... in no special order.....

1 flight hr so far, we switched several times...

LOVE ANR! we NOT going back!

ANR on, absolutely NO difference in the two headsets.

ANR off (or batts fail/go dead),

DC, OK, Passive NR not quite as good as my DC 13.4's.

Bose (ANR off)? They absolutely suck! Dono what is going on here...but
it was better when they were OFF (in the back seat)! Better carry a
spare (any!) headset on a long trip! I had heard about this, but
never expected it to be that bad. It was like the headset amplified
the engine noise, almost like it "echoed" inside the earcups.

Seriously, I would take them OFF and fly on without them on! Weird....

Audio quality, - Bose sounded a bit "better" for music (more "bass") ,
DC's have more of a "communication" sound quality. If coms were
difficult, I would give a slight edge to the DC's.

I liked the volume controls on the cord of the Bose..

The cell interface worked flawlessly on the DC's. - I called home,
bride could not tell we were in the air! She said my voice sounded a
little bit "nasal" ..like the hands free unit in my car (built into
the sound system)

The voice dialing (Blackberry Pearl) worked flawlessly... through the
DC interface.

Comfort..

Jury still out..

Cory has a "rounder " face than I.... he found the "undercut" earseals
on the DCs uncomfortable...they fit me perfectly.
Turned the ear seals upside down, he liked them!

The Bose were very comfortable for both of us, although the full
contact of the DC headband seemed a bit better than the two "pads" on
the Bose.

Interestingly, we tried the seals from my old DC's on the X11, and
Cory found them as comfortable as the "upside down" seals...
Thin eyeglass frames are important, there was a deterioration on the
ANR effectiveness around thick frames. (bothe headsets)

Clamping pressure is the same on both, pressing on the cups enhanced
the performance of both headsets.

AUDIO SEND?

Controllers here gave very good reports on the audio quality on both
headsets/microphones.

More to come..we gona try them again soon, we have them for up to 30
days to test.

So far, the ANR performance of the Bose do NOT appear to be worth the
extra $$ over the DCs. (depending on how you value that CD player they
send with it)

The cell input is a huge plus for the DCs if you use it. The music
input works well also...

We will fly them some more, and PIREP again..and let you know what we
decide - and why.

Cheers!

Dave
