1G iPod Shuffle charge and play

Question

Can I plug a 1G iPod Shuffle into the UBS power adaptor wall charger AND listen to it through the headphone jack at the same time?
It may seem like a stupid question but, I'm returning my 2G iPod because it can't do both at the same time.
New sales pitch:
2G iPod Shuffle, It can't walk and chew gum!

Answer 1

Wrong answer, unfortunately, and your example (while
correct - it won't play when connected to a USB port)
doesn't fit the question asked.
In fact, you CAN play the 1G Shuffle through the
earphone jacks using Apple's USB charger; many folks
are doing that in any number of applications where
they're just providing background music in a business
or whatever.
It plays out of the jacks, not out of the base, and
that is why it doesn't work on the 2G model; there's
no difference between the two and no way to get to
the audio on the provided dock (making me suspect
that some ingenious German is working up a modded
dock even as we speak, something that will be a
slightly bulkier version of the current one but will
feature an earphone jack .... it should be possible
to do that).
Not all USB chargers are created equal and, while
they will charge the Shuffle just fine, the shuffle
won't play. This has to do with how the pins are
connected in the charger bases themselves, and there
are several sites on the web which tell you how you
can work around that.
Thanks, that was my suspicion and hope.
I tried fabricating a 'y' for the 2G with a 4 conductor 3.5mm female (to the iPod Shuffle dock), 4 conductor male (to the iPod Shuffle) and a 3 conductor female for audio out.
If only the dock (which was connected to the USB charger) and the 2G Shuffle were connected, the Shuffle would charge.
If only the headphones and the Shuffle were connected, the headphones work, i stereo, no problem.
BUT, once you plugged in both the headphones and the dock neither would work.
Sent the 2G back ordered the 1G and am keeping the Apple USB charger.
Thanks
