Another very well-regarded headset is the Direct Sound Extreme EX-29. They are
often used in the sound studios for mixing. Specs say -29db isolation. Cost is
$119.95 on EBay.

Hi Anndel
I am not at home but as recall the gain setting I use its pretty
low as the mic int the CM500 is quite sensitive. I recall for EQ I
dropped the lowest down almost all the way and the next lowest just a
bit down. A for compression I am about 10 but a bit more would be
fine in a
Sam,
When this topic was previously discussed I saw mention of Extreme
Isolation EX 29 headphones which provide:
1) Good noise suppression (29 dB or nearly a factor of 1000 at 1000 Hz) so
you can keep the volume down and not hear your station's fans or the TV in
the next room.
2) Comfort
I've had Sennheiser HD400 for many years (long since out of production
but there is a newer model). These are very light. I've also the Heil
Proset noise cancellers. The Proset and any other can-style headphone

Hello folks.
I was operating yesterday with my K2 using headphones. I really prefer
headphones for weak sigs and operating in general but on two occasions
yesterday my ears were blasted due to a strong nearby signal. I finally
resorted to an external speaker even though can't hear with that
Hi,
Yes, the K3 has an audio limiter, but more importantly it's AGC can be
configured to virtually eliminate audio level differences once the signal is
above the AGC threshold. Not everybody likes this, but it will prevent the
experience you mention with the K2.

Chuck,
The K3 does have an audio limiter whose level can be adjusted - it can
be present when the AGC is off, there is a menu item to control it.
As far as the K2, try operating with AGC on, and the strong signals will
be subdued. Due to the slope of the K2 AGC response, you can still

Gary,
I use a 33 ohm headset with my K3. I have not noticed any reduction of audio
and the impedence match seems to be good. I use an AKG K240 Studio headset and
get excellent reproduction. Roy Morris W4WFB

Was it high or low impedance that was causing issues? I'm contemplating
plugging in two pairs of headphones which is probably going to put me
somewhere around 11 to 15 ohms nominal. I'm sure it'll do fine but
hadn't been able to find much in the way of specs for the K3 in this
regard.

My vote is for the 63 ohm Sony MDR7506 Professional Series
headphones. Add Garfield Headphone Sofites (just Google it), and you
have one of the finest, most comfortable headphones you'll ever wear.
Plenty of audio with the K3, and great for listening to music, too.

This is not always the case. The headphones that I'm
planning on using are Etymotic ER-4P's which are designed
with a low impedance to remain efficient with portable music
players but have very flat responses.
The dip in the top end is intentional
