After checking on the correct wiring issue Gene mentions,... I think you
will be able to use several high quality pro grade units used in the
recording and broadcast production business. They have a single ear
phone receiver and are usually wired to accommodate stereo jacks
properly, but with one receiver. But DO verify this before use. Gene
raises a good point, but one I think you can work around with care.
You COULD try the following sets:
1) Stanton makes an inexpensive one-sided headset for about $60.
DJ-PRO500-MC-MKII -- Should be OK - on par or better than
the popular Yamaha C-500
2) The Sennheiser HMD280-XQ comes in different impedance flavors
and with different connectors, and even with an unterminated
cable - but I have tried it and its mic element is weak, muffled
and particularly low output. I did not like it with my Omni VII.
I tried the two - stereo earphone receiver model, but the
mic is the same on both...
3) The Beyerdynamic DT108-200/400 is a popular headset and
hams I know like it a lot. I have not tried this, but several
hams I know have used it with various transceivers and all
report good audio sound in and out. It costs about $200
but you will have to buy a cable for it (sold separately)
for about $45-55 depending on vendor.
The Beyerdynamic DT280-MKII-200/80 also has a good
reputation and costs a bit more, maybe $250...
Same with the Beyerdynamic DT287-PV-80 for about
$260 plus cable cost.
These Beyerdynamic headsets come in various impedance
models - 80, 100, 200, 400 ohms, respectively, so you
gotta think when you order them. I do not see any
differences in impedance headphones on my Omni VII
but I believe I have seen references to differences in
connection with the Orion II - recalling a thread on this
some few months ago. If any problem, I would just get
a headphone amp for a cost of between $25 - $55 for a
good enough model and then you have MORE than enough
volume in your cans.
4) The Shure 512 is a particular favorite of mine. EXCELLENT
microphone audio out. Works SUPERB with my Omni VII.
It has an open air receiver that sounds good for communications
work but is open air - some guys want a closed cup earphone
receiver - but this is a good value for around $110 - $110.
I LOVE mine and may end up mounting the mic boom on
another headset someday. If you see a photo of the
Shure Model 512, then it appears to have two earphone
receivers, but the one side is a "dummy" to help the
headset hold in place ... sometimes it comes with this
empty receiver, and other times it comes with a "T"
pad to rest against the temple... either way supremely
comfortable. (Look at the HEIL BM-10 model which
uses some of the same parts... but the Shure is way
better microphone.) Can you tell I like mine? I use it
with my computer for speech recognition use... and
typically use an AudioTechnica BPHS-1 headset for
close cup use, or the Sennheiser HMD-45-6 for open air cup
use, on the transceiver.
5) The Eartec Co SLIMLINE-SNGL-MC1000 costs about $70 and
looks a LOT like some models of the HEIL line. I would
not be at all surprised if Eartec makes some of the HEIL
sets as OEM. I have not used one of these, but expect
it would work very well. The Eartec line seems to
have a good following.
6. The Sennheiser HMD26-600S is a fabulous piece of gear
but is very costly at over #350.
7. I HAVE AND USE the Sennheiser HMD-45-6 headset, but it
comes in a single earphone receiver version. Excellent
listen audio and wonderful microphone. Open air
earphone receivers - but Oh... what a great sound.
The mic gets excellent audio reports on my Omni VII.
8. Telex Airman headsets are popular among many hams.
These can be found in many single earphone models and
have decent microphones. Very comfortable. You will
be amazed at how closely they are made to the Shure 512,
and they share many of the same parts, just as the HEIL
BM-10 sets do. But the Telex models usually cost over
$175 and I can hardly think they are better than the
Shure Model 512 which costs nearly 40 per cent less.
9. The Telex PH1PT is designed with a single earphone and
mic for communications use, and is a substantial piece
of equipment for around $200. There is a whole line of
Telex single earphone models intended for use in the
industrial and recording or broadcast industry and often
used for intercom applications.
10. Some headsets allow either one or both earphone receivers
to rotate away from the ear. DJ headphones typically do this
so they can hear in and outside of the cans, at once. Perhaps
you would find you like stereo cans in one moment, and single
audio in another, and could use one of these rotating cup
designs. Or not... headphones are an immensely personal
item - like boxers or briefs...
11. Some guys like to fashion a computer type headset for use on
the transceiver. A couple of guys on eBay make simple, but
well-made adapters for your rig. Then, you can use a computer
type headset, which often come in a one-earphone design, but
are wired for stereo output jacks. I LIKE THE SENNHEISER
headphone line, and prefer the models with padded around-the-
ear cups, and padded over-the-head bands. Otherwise I think
BeyerDynamic makes a swell computer headset. Either the
Sennheiser or BeyerDynamic cans should cost you about $60
for a single cup model that is worth having.
I would stay away from any of the cheaper models made by
Logitech, Plantronics, ComputerAsscoates, Creative,
CyberAccoustics, and the like. Too cheap and lousy microphones
overall. The "work" but you have an Orion II... let's keep it
in good company, eh?
12. Most computer headsets have an electret condenser mic that
needs to draw 2.5 - 5 v from the rig. No big deal, but something
to contend with. Pin x on the 8 pin mic connector should
provide that voltage, or some guys use an external in-line
battery box for it.
I have some sound samples from some of these. I also have photos of
many of the models mentioned here.
See most of them at these sites:
Look under broadcast headsets, intercom headsets, aviation headsets,
recording headsets, and other classifications to be sure you have
covered the waterfront.
