your ears 
there a few ways you can do it,,, with a pair of ear defenders, some pipe, and a piece of copper pipe
or electronic stethoscope
i use the electronic type,,, and it has a volume knob

It looks better than wearing a set of det-cans going down the road!!

I read an article about knock sensing a while ago, the electronics appear quite simple, but the sensor that attaches to the block needs to be tuned into the particular frequency of each block. Finding the right sensor might prove difficult.

I'm using the KnocksenseMS from here:
http://www.viatrack.ca/
Works well with my management richening the mixture, retarding spark and making a mark in the datalog. Also drives a led, which I've hidden in the original tach.

ear muffs and tubing are as cheap as you can get, and pretty damn good once you know what to listen for.
Although for a permanent install, the knockilnk is pretty good too.

I tired the original Autospeed electronic version. It picked up so much background noise it made them very hard to use.
I did hear a guy on another forum, say he simply attached the knock sensor to a pair of headphones, and they worked for him.
No idea what it would sound like, or how loud it would be.

depending on the type of knock sensor this can work (with a small amp) i got a sound file somewhere with it on ill see if i can find it

all very interesting stuff.
Whats wrong with just a stethoscope, plastic tubing (lagged in engine bay to avoid outside engine noise/bumps/rubbing etc) and attached to a head stud via a steel hook?
thats what I've been using, and although I havent spent too much time, i could certainly detect the traditional 'tink tink' when the ignition was advanced considerably.

Any electrical system can pick up valve train noise etc, cant beat a well tuned ear if its for mapping, but the electronic systems are good as a warning if something appears that wasnt there before.

Better for what?
If you mean for mapping, then definately not, det cans (or electric scope) all the way IMHO
If you mean for installing in the car to give you a warning if something changes, then they are a great option providing you dont get unlucky with other noises on the same frequency (not common to have a problem, but it does happen sometimes)

I use a pair of quality ear defenders with some short sections of 5/16 copper pipe arraldited in.
These are then connected with some air line pipe and a Y piece to a longer piece of copper pipe that has the end flattened.
A hole is then drilled in this and is bolted to the engine block.
Work a treat and det can be clearly heard. The better quality ear defenders you buy, the more out side noise will be blocked out and the easier it will be to hear the det. I use a set of Peltor ones.
Gameboy..... thats an innovate LM1, best affordable wide band you can get, i reckon.
