A Word In Your Ear
this iphone headset is so light you can barely feel it
By steven cherry
Like most things Apple designs
these days, the iPhone bluetooth
headset (uS $129) is elegant
and simple. Most of all, it's tiny-
the smallest bluetooth headset
I've seen. It's so small, in fact, that
Apple designed a special travel
cable for it. Instead of the usual
30-pin uSb cable-good for iPods
and the iPhone-the 30-pin end has,
at the back, a slot for the headset's 2.3- by
5.0-millimeter slanted tip.
The advantages when traveling are
enormous. Now, not only can you charge
the iPhone directly from your computer
with just this one cable, you can also
charge your headset without bringing
along a power cord for it.
Even though there's no separate cord
for the headset, there are other charg-
tools & toys
international environmental policy at Tufts
university, in Medford, Mass., note that
addressing the problem of climate change
will require a fundamental restructuring
of our energy system. They correctly suggest that if done properly this restructuring "could be relatively painless." however,
as at the end of Al gore's documentary, An
Inconvenient Truth (2006), when a somewhat random list of remedies scrolls past
viewers, Layzer and Moomaw bounce
through a potpourri of technologies and
policies. This treatment fails to paint a compelling picture of what the united States or
the rest of the world should do.
The book would have benefited from a
one-page list of suggested further readings and Web addresses for those who do
not know their way around this subject and
would like to read more.
n
ing options. The headset
comes with a dock. Also,
at the uSb end of the
30-pin cable there is
the power adapter that
came with your iPhone. I
was able to charge the headset
from zero to full in 90 minutes,
just as the diminutive manual
had claimed.
So how does it rate as a headset? It's incredibly light, clinging
to your ear by only its speaker, an
arrangement I found secure enough
when walking down the street but rather
less so when engaging in more strenuous
activity. Salespeople at the Apple store said
that the precarious fit explains why a lot of
people prefer designs that hook around the
ear, such as the Jabra JX10.
