Think it varies rather widely from model to model, but main thing is volume
output means something along the lines of the louder you go, the more power it
takes.
For example though, my other portable inline amplifier reckons earphones with
lower than something like 3.5ohm resistance won't handle it's 400% amplified
signal too well.

I noticed on the specs of many earphone types, they have the same R value as
normal speakers do. It would pay to find electrical resistance of these items,
to be sure. This fact surprised me many years ago, so my data may be out of
date, admittedly.

Pretty sure general earphone usage of something like a netbook wouldn't
really affect it's own battery life as such - whereas if you used something
like an actual built in speaker or something that would most likely drain more
power.

This answers my previous questions, both sender & receiver are battery
powered. Would this extend battery life of net books (etc) appreciably? Or is
battery drain from earphone use, negligible, and not an issue here?

Ok, this is partly relevant, since I got hold of it specifically for use
along with my screen reader in an open plan office environment, etc.
Anyway, had been looking for some form of wireless headset for a little
while that would preferably be somewhat portable, would be battery powered or
rechargeable on both ends - base/transmission unit as well as
headphones/receiver, etc. etc., with part of the idea being that while do use
normal headphones, the lead sometimes gets in my way when I am trying to do
things with my hands, inbetween typing on the keyboard, etc., and sometimes it
would just be nice to not be restricted by an audio lead, etc., and the sort of
final thing is sometimes it might be nice to use an audio gadget of sorts
without it being too obvious that I had earphones in my ears, etc., but that
one's still not perfectly doable due to the size of the headphones, but at
least they're relatively comfortable/lightweight.
Basically it's a base unit around 20cm high when standing up, around 3cm
thick, and around 10cm back to front, and it can run off 3 AAA batteries in
both base unit, and headphones, which while they're ones that fit over your
ears, they're relatively lightweight, and quite comfortable.
The base unit also has a DC power socket, but it didn't actually come with
the relevant power unit, but that should be easy enough to find at the right
sort of shop since it's generally just the diameter of that socket that makes
sure it's the right voltage, etc.
What you do is turn on the base unit, and then turn on the headphones, and
it has it's own volume control, and a microphone input socket, and then also
another 2 press buttons on it, which let you reset it to base unit reception,
or to sort of scan through FM radio channels - so it sort of doubles as a
battery powered FM radio if you want that.
On the base unit, there's an on/off slider switch, and another slider
switch that lets you switch it between audio input, or acting as a form of baby
monitor/spy device where it uses a built in microphone to then let you listen
to what's happening around it, and the stereo audio line it comes with also has
a standard RCA converter lead to let you plug it into things like TVs, etc.,
but anyway.
The range is meant to be around 10 meters, but depending on surroundings,
it actually seems a little bit further transmitting than that - sometimes
anyway, and while it's not the loudest set of earphones, they do seem to
provide pretty decent sound quality, and it does also handle stereo well enough.
Lastly, while had been asking one of the local, decent computer shops to
look for something like a bluetooth unit for me, etc., they firstly seemed to
think these weren't too easy to find, and the prices they came back with were
around R700+, but when happened to be in a smaller local computer shop this
past weekend, that, among other things sells some other gaming accessories, and
second hand PC games, etc., I asked them, and they had this XGR set there on
the shelf, for R140, and it's full name is something like an XGR 6 in 1
wireless headset including FM radio, microphone support, etc.
Like said, primary thing is it will let me avoid using normal headphones
with a lead, but would also let you, for example, listen to an audio
book/podcast from a little bit of distance away from the output source if you
wanted to, or could be used as a sort of spy device to listen to something
happening next door whithout being physically present - sit in on meetings,
whithout being present...<smile>
