Build and Construction:
Build quality appears to be excellent with a solid feel where you
would expect it and soft rubber where you need it. The
plastic used feels expensive with switches, connectors and buttons
all feeling solid. The appearance color is silver and
black. The connector for power is along the back of
the unit and mates with a small connector in the wall charging
adaptor that can also plug into the cradle for when the unit is
plugged into the cradle. The user manual calls out figures
to show you various aspects of using the headset however the
figures are not in the manual.
Comfort: Comfort is
always subjective and I must admit that I am biased toward ease of
use with glasses since I am always taking them off or putting them
on. This headset does only includes a single size rubber
ring, though a few creative folks have installed other Jabra ear
gels. I found this headset to be a little uncomfortable and
I found I needed the ear stabilizer to ensure I wouldn't lose
it. I was thinking of modifying one of those super soft and
comfortable ear gels from the Plantronics 640 and trying to adapt
it. The rubber is a little hard and when I compared it to
the Nokia BH-800, I found the Nokia with a slightly softer
compound to be more comfortable. For small ears i suspect
that this will be an uncomfortable headset for many. I was
able to put on or take off glasses without any problem. It
is not as comfortable to me as either the Plantronics D640 or the
Plantronics V510 though the 510 is not a true in the ear
headset. Different ears may have a different experience.

Connectivity: Pairing
is easy. You put the unit into pairing mode by turning it on
and then pressing the very tiny pairing button seen on the bottom
of the unit until the LED flashes blue. You then use
the code of 0000 in your phone device to establish the
pairing. I had no problem pairing it to a BB 8700 and a Moto
Q. I have been using it for about a 2 weeks and I have not
experienced any pairing issues or disconnects. I have not
had it drop a connection while in use and I found in my distance
test it had a reasonable range. I have not noticed static
whether placed on the same or opposite side from the handset.
Sound Quality:
Incoming sound quality is also very good but not as good as either
the Plantronics V510, D640 or the AX-2 Pro. Volume appeared
to be adequate for noisy environments Outgoing sound quality
depended heavily on the environment but even in a quiet
environment it has a digital sound to it that I find a little less
pleasant than the more analog headsets. During my testing I
received a software upgrade that I applied and it helped a little
(or I at least imagined that it did).

Noise Cancellation:
Noise cancellation is only adequate. In every test you can
hear the background noise and at high levels it overpowers the
speaker and causes the audio to become choppy. The D510 was
clearly superior in this category. I have not yet tested in
windy conditions.

Ease of Use: The
unit is easy to use with just three buttons, one being a multi
function button for connecting, disconnecting, and powering on
& off. The two rear switches are for volume. I find the
unit easy to use and comfortable. It is small but well
designed so you don't have to struggle to find the right button to
use when you need it. There is a very small pairing button
but since you only use it once to pair it is ok.
Other Comments: If
this unit had the ety*com noise canceling mic it would be a
substantially better headset. It is the best Jabra so far
and they will undoubtedly improve it with the next version. DSP
just has not worked as well as it is hyped. It seems to hurt
sound quality on both ends. My suggestion is to remove the
DSP and add a clear thin noise canceling tube mic like those used
by stage performers and a softer ear gel.
