Here's an update on the Lightspeed 25XL ANR headset. As you recall, Marv
and a few others had done some comparisons at Sun N Fun - Marv didn't think
the 25XL was at the top of the heap - especially when price was factored in
(it sells for about $585 vs about $300+ for some other ANR headsets)
I flew to San Jose this past weekend - about 650 miles from the Olympic
Peninsula - in my Beech Sierra. First x-country since acquiring the 25XL's.
It took about 5.5 hours down and about the same on the return. I found that
the noise reduction was tremendous when compared with what I'm used to with
my Dave Clamp headsets. Also they were extremely comfortable for both my
wife and me. I'm used to getting a splitting headache after a couple of
hours in the air and having to take the headset off for a few minutes to
relieve it. No such thing here even when wearing sunglasses under the
earpieces.
Marv mentioned that when he turned his head while trying the lightspeed on,
the earcups would break the seal over the ear and a loud buzz would occur.
I found this to be true also. It seemed difficult to adjust the headset so
that the best fit would minimize these episodes. I was able after practice
to almost eliminate this problem. However, I like to move my lower jaw back
and forth when changing altitude to facilitate normalizing airpressure in my
ears. Whenever I do that with this headset, the seal is broken and that
buzzing happens. I think this is a pretty major drawback for the 25XL and I
might not buy them if I had it to do over again. I'm not sure but I think
this feature is part of the auto shut off circuitry that turns the batteries
off when the headset is taken off for any length of time. On the other hand
it could be simple feedback from overdriving the ANR circuits with too many
decibels.
Will let you know if I find out more.
