Bluetooth Noise cancelling headphones

[Dave Sublette-2]

Good evening,

A few days ago I posted a question about using Bluetooth headsets and the
latency problem.  I got no answers, so I just took the bull by the horns
and ordered something.

Today I received the Avantree Audikast aptX low latency transmitter and the
Avantree ANC031 Active Noise Canceling Headset.

After three hours charging the headset, per the instructions, I hooked it
all to the headphone output of my KX3.

It works!  There is no detectable latency.  I can send and receive Morse
without stuttering.  I can't hear any latency at all.

I walked the entire length of the house, about thirty feet in each
direction with walls, etc.  I can hear the receiver just fine.  One end of
the path is in the garage where my workshop is.  That gives the possibility
of listening to a fixed or scanned set of frequencies while I am working on
something else.

In short, it appears to be just what I wanted.  Now I won't try to break my
neck or drag all the radios off the table when I jump up to go get another
Pepsi out of the fridge.  :-)

No connection to selling these products here.  Just reporting the results
to to this point.

I may report again after I have used it awhile.  The battery charge is
advertised for 40 hours.  I'm sure I will put that to the test.

73,

Dave, K4TO

I have some nice Bluetooth active noise cancelling headphones. They're a
folding set made by MPOW that I don't think they make anymore. You can also
plug a 3.5mm stereo patch cable into them and not turn on the Bluetooth
section, though you can still turn on the active noise cancelling
separately.

I've used them with several devices and they seem to work well. I've used
then with the patch cord to the KX3 headphone jack, and they work just
fine, but that's scarcely a test. I don't know how I would test the
Bluetooth function with the KX3, as the rig doesn't have Bluetooth output
that I'm aware of. I'd have to use a separate Bluetooth transmitter, which
I don't currently have.

The headphones I used are these, that I purchased at the time on Amazon.
Unfortunately, they are no longer available.

These appear to be a more recent model with similar functionality.

Thanks Kevin.  Did you order the same models as Dave?Interesting to read that the low latency features only work with their brand headphones. I believe I saw that on Amazon who also carrys the Avantree brand.   I'll probably get the non noise cancelling model headphones as I have a quiet shack.  Although now that I think about it maybe the active noise cancelling model would be good for traveling and FD/multi-op contesting. 73,Gary K9GS

I have some noise cancelling headphones which I sometimes use to
quiet airplane noise. They make it possible to listen to music
without blowing out my ears from too much volume.

I always use them when our ARES/RACES group does communication
for the Los Gatos Children's Holliday Parade. I can actually
hear net control with a marching band next to me. (I also use a
noise cancelling mic.)

I haven't used them during CQP, but the RadioSport headphones I
used last time really kept the outside chatter down. They should
be useful in a tent/room of SSB operators.

Since they work as normal headphones when the noise cancelling
feature is turned off or the battery is dead, they are useful in
many places.
