"If the click seems to come from right inside your head - game over".

What more do you need? Phil's given you a test to see if the phasing is
correct, can you not figure it out, or what to do if the click seems to
come from your right or your left?

** If both ear phones work but are wired out of phase, the AA cell click
test produces a sound that seems to be originating outside the head on
both sides. Mono speech or music sounds much the same.

The effect is far MORE pronounced than with typical stereo speakers in a
room.

The OP demonstrates his a monumental ignorance of headphones, hi-fi
sound, usenet etiquette and common sense.

Only tangentially related, and mostly useless:

Amateur radio folks like building direct conversion receivers (i.e., mix
down to baseband). They're simple, hence little, and they work pretty
well. Their biggest problem is that they have no audio image rejection
at all -- listening with a 7040kHz oscillator, you'll hear a signal at
7040.5 just the same as one at 7039.5.

That's the _second_ biggest problem - the biggest is that they're an
unlicensed transmitter.

Hope This Helps!

No, it doesn't help and is misleading, Rich. 7040kHz is an amateur
frequency. So, it is legal for "Amateur radio folks" as Tim indicated.
