I have two - one of those and another variant in the same price range
(half the price).

They work great. Use them at Field Day to supply guest headphones for
visitors as well as ops. The older ops appreciate them as well because
some of the newer radios don't have enough audio even without
splitters. Everyone gets there own volume control. No hint of RF even 
with 1000 watts at home. Misplaced the power supply for one once. 
Ran it all weekend on AA batteries so if you wanted to toss the wall 
wart - that works too.

I found one thing to be aware of. I use one when I go out mobile.
I believe the one you posted has a negative center pin on the power.
I blew a fuse in the truck when the coaxial power plug accidentally
popped out and touched a ground point.  <grin>

The next one I bought, I made sure it had a positive center pin for
the power.

Has anyone bought one of these?

I'm thinking for this up coming contest season, inviting over a bunch of 
non-contesters to give them the experience and maybe get a few more bit 
by the contesting bug. And this loos too good to be true, the 
distribution machine AND 4 headphones?  this if it works would be great 
to have so rveryone near the radio can have a headset, and even maybe 
use one of the outputs for a regular speaker too?

My question is do you have one and how well does it work?  how about 
RF?  does it have any problems with RF? My computer has nice sound 
system speakers for music  sub woofer and all that But i have to shut it 
off when transmitting because RF gets into it. (everything is plastic.)

so  anyone?
