Noise Cancelling Headphones

I am looking for a pair of noise cancelling headphones.

I have a pair of Sony MDR-V6's that I love, but they do not have noise
cancelling capability and my wife's embroidery machine is severely
limiting my radio operations.

I have already looked at the Yamaha CM500's because they come so highly
recommended on this group. If they're noise cancelling, I cannot find
that information about them.

I want something that will last. The MDR-V6's have lasted at least 10
years if not longer. I've only had to replace the earpads.

I want something that *covers* my ear *not* something that sits *on* my
ear. Those that sit *on* my ears are uncomfortable after a very short while.

Merry Christmas and 73,

Joel - W4JBB

I use Bose Quiet Comfort 2 with the K3. Very effective.

I use a set of Senheiser noise canceling headphones when our
ARES/RACES works the Los Gatos Children's Christmas parade. They
are comfortable for at least a couple of hours and help hearing
when a marching band is playing nearby.

They aren't noise canceling, but my wife complains that I can't
hear her when I'm wearing them HIHI.

I have the Bose Quiet Comfort 15 I use with the K3 for CW weak signal work. Perfect for field day with the generator hammering away outside the tent. You can disconnect the audio lead and use 'em for quieting on airplanes, etc. They fit over the ear and the seal is effective and comfortable.

They use one AAA battery which lasts for 24 to 30 hours of use.

The Radiosport RS 20 headphones are the way to go. They're not cheap,
but they really do the job. They have NO electronic circuitry to give
RFI problems, just 24 dB of noise reduction due to their excellent
acoustic isolation. When I have them on with any receiver audio at all
going I can't hear the phone ring on my operating desk. They're also
extremely comfortable -- the only headphones I've ever used that let me
operate the full 24 hours of Sweepstakes with zero discomfort. Their
build quality is light years beyond the cheap plastic construction of
the Heil, Bose or Yamaha phones. The RS 60 has the same headset with the
addition of a boom microphone for phone operation.

I tried them, and found them to be VERY VERY uncomfortable, to the point
of being instruments of torture. I'm a contester, and often am in the
chair for 20-30 hours in a weekend. I couldn't wear the Radiosport cans
for an hour.

I'd rate the acoustic seal of CM500s comparable to Sony MDR7506 /
MDR-V6, all of which I've owned and like a lot. In other words, if
you're not happy with the MDR-V6, you won't be happy with the CM500. :)
I have heard that east coast contesters love the Bose noise cancelling
headphones, but I've never heard them. I did try a pair of Sennheiser
noise cancelling headphones almost 20 years ago, and they seemed to
work, but I wasn't being critical, and that was 20 years ago. :)

The best, and most comfortable, noise isolating headphones I know of are
the Etymotic Research ER4-series in-ear earsets, I own two pairs, and
wore out one of the cables. They come with 3-4 generic ear fittings, and
I found one of them to work well for me -- good isolation and comfort.
Cost was about $200 eight years ago when I bought them. The greatest
isolation is achieved with custom ear molds, which you buy from an
audiologist who fits them to your ear canal.

Re: Noise Cancelling Headphones

I use the Bose QC-15 as about all I do is CW and the audio on these
is wonderful. The noise cancelling though is almost 100% perfect; my
old Alpha with its blower is 18" from my head and with the QC-15 on I

can't but just barely tell the amp is on or off.

I was thinking about getting a headset with a mic & though Bose does
make the A20 for pilots, at $1100 for what is essentially the QC-15
with a boom mic, I'll pass. They do make a A100T snap on mic for the
QC15 but they are $250 for just the mic. I was referred by quite a
few people here to check out the Yamaha CM500 for a fine mic, quick
match to the K3 and comfortable headsets & at $59.

I'm so happy with the Bose QC15 that I'm going to keep using these
and am going to need to figure out another way to get a mic into the
K3 in a way that will be convenient for contesting should I ever
decide to do a phone contest. I have an Electrovoice RE-10 which
would probably be nice & needs no power & maybe I can make a clamp-on

boom that I can remove from the desk once the contest is over. I also

have several condenser mics but they are for recording and would be
excess and just problematic for ham use.

Anyone have any suggestion of a removable boom mic other than the
A100T that will attach to the QC-15 and make it simple to use and
then remove when the contest is over? I don't want to use velcro.

Thanks & 73,

Gary

Re: Noise Cancelling Headphones

Is there such a thing as a noise cancelling black box you can plug in a
headset such as the CM-500 and get good noise canceling? No knobs. Just an
ON-OFF switch like the headsets have.

And thinking of the CM-500. Has anyone found a set of material covers that
fit their ear covers? I would think they would be more comfortable than the
plastic against your head. And they would look better than the pieces of
paper towels I presently use when wearing the headphones for extended
periods. :-)

Re: Noise Cancelling Headphones

I've never tried noise cancelling headphones, so my one question is, does
anyone detect ANY effect to the desired audio? In other words, any
"Noise-Blanker" effects or coloration of the audio?
I would suppose that, since they're designed for music, the noise cancelling
function is transparent, right?

On the very few flights I've taken recently, I successfully used my old Sony
MDR-7506's. Maybe I don't know what I'm missing by NOT using a noise
cancelling set.

Re: Noise Cancelling Headphones

The Bose QC15's are very nice for sure. The price, as with all Bose
products, is way too high. I use them for CW/ digital contests and the
CM-500's for phone contests. I like the CM-500's very much. They are very
comfortable but do not have the isolation that one would want in a multi
environment.
Hope everyone had a very special Christmas day!

I use custom ear molds when on a long distance motorcycle rides. They do provide great isolation and are comfortable for long periods. I've been using the same set for 7 years with no issues. In addition to audiologists, vendors are usually at major motorcycle shows and sometimes at m'cycle shop (espec BMW) open houses.

I still use the Yam headset with my new KX3 as I don't have a boom mic. The Yam works well for long periods too.

In reply to this post by Gary Smith-2

I also really like the bose qc15 headphones and had been considering one of the add on
microphones that are available, like

Expensive one
http://uflymike.com

Or
http://www.headsetbuddy.com/clearmic-noise-canceling-microphone-for-bose-qc15-headphones/

Or more generic
http://www.modmic.com

Or DIY
http://www.freewebs.com/k1dg/boseheadphonemod.htm

The qc15 comes with a mic as well but not a boom style, just on the cord like for iPhones.
The qc15 was more comfortable for me in a 32 hour single op rtty contest than my other
choices. The noise canceling does not have the hiss or the distortion of rtty side tone and
noise like the cheaper noise canceling 'phones do.

I have decided for my limited ssb operation I think my cm500 or heil proset will do just fine.
(Well at least for now)

Re: Noise Cancelling Headphones

In reply to this post by N2TK

The noise pickup must be very close to the ear piece to allow proper and constant phase for effective canceling. Having a separate box would mean the phase would change if you moved your head so would't work.

I haven't noticed any "noise blanker" effect. There are surely minor errors in the canceling process but Bose seems the have it pretty well worked out. iPod music is great through them even at 40000 ft. :-)

These have caught my eye at my local Costco recently:

http://www.costco.com/Sony-MDR-10RDC-Premium-Noise-Canceling-Headphones.product.100083695.html

The reviews seem decent. They probably don't have the same
construction quality as your MDR-V6's (guessing), but may be worth
checking out if you're a member, or know someone who is...

Re: Noise Cancelling Headphones

I just read the second page of reviews, and there are a couple of
complaints about picking up FM broadcast radio stations. That may be a
bad sign! I have the old Heil ProSet QuietPhone (with the NC lump in
the cord), which was horribly susceptible to RFI. Something to look
out for on any model you choose. At least with the Costco one, you can
return it to the store if it doesn't work out...

Being a retired audio pro who has done a lot of recording, I have a lot
of pro mics, including several RE16s. Before I discovered the CM500
(thanks to W6XU, another audio pro), I used an RE16 in my ham station on
a boom stand. It worked quite well.

The hookup of a pro dynamic mic to ham gear is very simple. Pro mics are
wired balanced via shielded twist pair cable to a three-pin connector
called an XL. Pin 1 is the shield, Pin 2 is "high", Pin 3 is "return."
To connect a dynamic mic like the RE10, wire Pin 2 to mic in on the rig,
wire Pin 3 to mic return on the rig, and connect Pin 1 to the chassis. I
made up some adapters for the various rigs that I used that mic with.

Nearly all ham mics have a peaked response in the range of 3 kHz to
compensate for the rolloff of SSB filters, both on RX and TX. This was,
I believe, first developed by Shure about 40 years ago, and you can see
it in the response of their communications mics. Pro mics don't have
this peak (or if they do, it's in the range of 8-10 kHz), so TXEQ must
be adjusted to provide that peak. I used the same low frequency rolloff
for the RE10 that I use now for the CM500 -- the three lowest frequency
bands max cut, the fourth cut by about half, tweaked by ear based on the
reports of a known good listener. For the high end, I boosted the top
band by about 10 dB, the next highest band by a few dB, again tweaked on
the basis of reports from a good listener.

With rigs other than a K3 that don't have TXEQ, I added a capacitor in
series with the mic wiring to the rig input and a resistor between the
rig mic input and mic signal return. The resistor was about 470 ohms,
and the capacitor value was chosen so that the network produced a strong
rolloff below 2 kHz -- in other words, a sloped response that peaked
around 3 kHz. I got very good audio reports from this simple setup with
a TS850, an Omni V, an FT1000MP, and a K2.

I modified the K2 to add a low frequency rolloff around 400 Hz also to
increase the mic gain by about 6 dB. I did this simply by changing the
values of a few resistors and capacitors early in the audio signal
chain. The purpose of the mod was simple -- with most ham mics, the K2
is a bit low on gain, so I wanted to hit the limiter harder. I also
wanted to minimize the wasted LF energy, and also prevent that LF energy
from activating the limiter.

73, Jim K9YC

Is it worth 180 bucks?

Maybe, if you operate in a noisy environment. The Bose QC15 that
others are raving about sells for ~$270 !
