See the thread

for some ideas. You can either build the amp as-is and drive the headphones through resistors, or scale the amp to drive headphones.
You could also build a separate buffer for your headphones. See http://www.headwize.com [Library\Projects] for lots of ideas.

hi, .. good idea, we (Paulb and I) have discused it else were on the forum ... a 120-120 ohm resistor in series or as voltage divider would work fine for 32 ohm headphones.. I gonna put my idea's on my webpage soon.. I'll let post a forum topic when I do...... Headwize is an excelent site!!

greetings

Hey, tschrama, thanks for the tip on Circuitmaker. I'm simulating mods to the Szekeres buffer amp, it is a lot of fun.

Hello,
i use to hear with my Sennheiser HD 600 with 300 Ohm impedance. I think this will roll off the lower frequencies, when i connect the headphone at the bride of zen.
What about to connect at the zen amp?

You can feed the BOZ into a "Szekeres" buffer:

I know somebody on this forum has talked about this...

To connect to the Zen amp use a dropping resistor or divider as tschrama says.

p.s. Nice headphones you got there, Hauke.
