Default In-Line Amplifier for Headphones?

I have a pair of headphones and they don't get quite loud enough for my
tastes when connected to my MP3 player. I'm wondering if there is an
affordable device which can be connected in-line to the 1/8" headphone jack
which will amplify the sound at little or no quality loss--and isn't huge.

Maybe something like this?

This one gets good marks but will cost you $200.

I have one of those Radio Shack things that take 2 AA batteries
(Boost-A-Roo, I think). Sound output is poor as far as I'm concerned and
the bass distorts at higher levels. Seems the amp in it just doesn't have
the poop to run it LOUD and the 18mw output of the player is pretty much
what comes out of the R.S. toy albeit with more distortion as well. Running
it into two phones was pretty much a disaster too (that was the intended
use). The phone jack inside the thing has oxidized over time and now I need
to twist the heck out of the plug to keep it singing, along with spraying
some No-Noise into it to quiet the jack-noise down. Of course, this was one
of the early models so it may have been improved since, but I doubt it will
equal anything like the above HeadRoom unit.

HeadRoom also carries just about all the earphones and cans made and gives
their rankings on them as well. Personally, I'd shoot for the ones they
don't carry: Sensaphonic's Prophonic Soft 2X, but at $900 a pop they'll
have to wait until next Xmas. Funny, I didn't see the Sony MDR-R10 Home
Style Headphones in their sales cart. Okay, so they retail for $3999.99
(oh...Amazon has them on sale for a mere $3799.99 !!)

Try this:

Hardly the last word in sound quality, but more than fits your specs. I
found it quite listenable with my Zen and 580's.

And these

sound way better than they have a right to at $20!

The problem with the Boostaroo is that it runs off of a 3 volt supply,
as does much of the equipment that it is designed to boost. Basically,
if you want louder sound you need both more gain and more output
voltage capacity. Boostaroo has the extra gain, but it may not as
supplied have the extra output voltage that you may require.

OTOH if you use a Boostaroo with a device that runs off a single AA or
AAA cell, it will provide a loudness advantage.


My solution to the Boostaroo's output voltage limitaiton is to operate
it from a power supply with higher voltage than a mere 3 volts. I
modifed a scrapped Comcast 5 volt power supply by adding a couple of
dowels and brass screws that simulate two cells. This nearly doubled
the Boostaroo's maximum voltage output. I think that this is about the
limit of its basic design.

Wroks for me!

Head-fi.org is a web site devoted to high-fidelity headphone listening.
Visit their amp forum to learn more about various amplifiers. Beware,
they discuss sound quality like Californians discuss wine. They also
have a for sale forum where you can get deals on used equipment.

Smother slowly for at least 2 hours, adding small amounts of water
when it starts to stick.
Stir frequently.
When ready - serve with rice, grilled smoked sausage, green salad, and iced tea.
Coffee and apple pie then brandy.
