[Elecraft] OT: Yamaha 'phones specs: has the world gone mad?

[pd0psb]

No Doug, the world has not gone mad :-)

What you seem to overlook is that reproduction (even in communications) has
to be linear.
Be it from 50-8000Hz or from 300-2700Hz or 400-600Hz, that's not important.
Within the chosen passband response,filters and transducers should be linear
for faithfull reproduction of signals.

If you buy a radio with variable bandpass and TX/RX EQ, the headset <imho>
shouldn't limit your options.
And a 20-20000Hz headphone *may* perform better at linearity...
