These issues are very personal, and depend a lot on what we're used to 
and what we've experienced.

I'm retired from a career in pro audio, and am a Fellow of the Audio 
Engineering Society. Except for casual monitoring while I'm doing other 
stuff in the shack, I use headphones for 99.9% of my operation. My 
headphones of choice are Sony MDR7506 and Yamaha CM500. Both provide 
excellent communications quality RX audio. I don't use ham RX to listen 
to broadcast audio -- I have other radios for that purpose.

As to user interface -- Elecraft has done a great job of learning what 
controls most hams need on a daily basis and which can be on menus. 
Everything that I've ever needed to adjust while operating is either a 
button or a knob on the front panel, or can be assigned to either of two 
"soft" buttons on the front panel. In 8 years, I've found only one 
function I wanted to assign -- toggling the speaker on and off with my 
Yamaha CM500 plugged into the rear panel.

Indeed, the "complexity" is nothing more than giving the user more 
control of how the radio works than do most other radios. This control 
is on menus, AND menus are only needed when you want to change how the 
radio works. The K3 and K3S work just fine with no adjustments to any of 
those menus to work SSB or CW with a mic and paddle plugged into the 
front panel! Exception -- VOX Gain and Anti-VOX are on a top-level menu. 
If you want to plug your CM500 (or other boom mic headset) into the rear 
panel, you'll need to go to a menu to select rear panel mic and hit a 
button (2 on the keypad) to turn on bias. Again, that's a one-time setting.

More complexity -- the K3 and K3S have TX modes optimized for digital 
modes and for RTTY. You need to select the right method for the way you 
want to TX these modes. These are, for most of us, one-time settings. 
Less complexity -- both K3 and K3S have a Line Input to feed digital (or 
SSB messages) from a computer, so you don't need adapters to the mic input.

But all the controls you need while operating are on the front panel -- 
IF bandwidth and shift, Mic Gain, CW speed, Audio Compression, Power 
out, RF gain, AF Gain, RIT/XIT, preamp on/off, Atten on/off, Ant1/Ant2 
toggle, Tune button, Ant Auto Tune, Mode, Band, Spot, Notch, NB, NR, are 
all on the front panel. Want to go into Split Mode? Hit A>B twice in 
succession to copy A VFO settings to B VFO, then push and hold A>B to go 
into split, then tune the B VFO where you want to TX.

Hope this helps to correct some misconceptions.
