As a young pilot, the Bose X semmend like an awesome headset however
$1000 is just too much money to spend for me. I looked around and found
the QFRXCc for $230 retail! I finally decided that in case I wasn't
happy with I would just return it.

Peter,

I doubt any
patent challenge for a device that turns itself off after a period of
inactivity would stand up to any scrutiny.


I think the patent relates to the ANR circuitry sensing that it's not
on a head anymore and shutting down because of that.

I wonder how they do that. I believe the Bose just uses loss of
signal on one or both of the connectors to sense it's not plugged in
any more and shut itself off. Unless they have a sensor in the spring
to figure out whether the headset is open (thus on someone's head) or
something, I doubt it's substantially different, but freely admit I
don't know. Suffice it to say, the Lightspeed is not the only ANR
headset that shuts itself off.

My wife bought a pair of Sennheiser PXC 250 for her iPod. They're
actually pretty nice, but I swear that they're not really noise
cancelling--I think that the electronics just adds a bit of white
masking noise and turns up the volume five or ten dB. Does anyone know?
Sennheiser's ad copy is that they have "NoiseGard active noise
compensation."

Anyways, flying with it was just great, the best $230 I have ever
spent!! Passive anutation is great but the magic comes when you turn
the ANR on, I could not believe the difference the ANR made by
switching it ON and OFF.
The headset doesn't clamp at all, after flying 2 hours and 3 hours my
head does not hurt. Compare to the Bose X, I think the headset is
holding up pretty well. The Bose is still quieter but also almost 5x as
expensive.

The power for the ANR is supplied by 2x AA batteries in the battery box
which also has two sliders to control volume in each speaker; it also
has an aux plug to connect your mp3 player or cell phone! Great Headset
I absolutely love it!

I got mine from Rollison Airplane Co. for $275 plus shipping. They're
fast and friendly!

Peter,

I wonder how they do that.


The ANR circuitry can be made to sense an open earcup, I'm told.
