well i'd like to get something for $50 or less. i have a good pair of grado's, but the imperence is too low for the use i need it for. so i dont need another expensive pair, this is just for taking on holidays, sitting on the couch, etc with my behringer vamp2 - which is too loud on my grado's.
I'm not too certain you'll be able to find high-impedance phones in that price range. Maybe I just haven't found them myself...
I use AKG K240, which are 55 ohms (around there anyway) and cost $100 at most GCs and online stores. Own two pairs, work great, sound great, durable and functional. Oh, and comfortable - that's key with studio headphones. They are not suitable for use in a studio (I use them in the control room) as they're not fully sound-isolated.
The newer \"studio\" model (K240S) has a low impedance (55 ohms). But the original K240M is much higher - 600 ohms. It was known as \"hard to drive\" because of this and its inefficiency. But for THIS use, it might be perfect.
600 might be pushing it. 300 should be more than enough to drive with good S/N. For what he's describing, 55 ohms is just fine, though I could be wrong.

Could be. Best way is to find a store with headphones that can be tried, and take the V-Amp there. Even if no phones they have fit the bill, it should be educational, especially if he knew the impedance of all the phones tried.
i just bought a pair for sony's for $39 with 70 ohms and i heardly noticed a diff between them and my 32ohm grados, so im taking them back. 300ohms might be needed, i'll look into it.

I suppose I'm wrong. But you should do what jester said, go out and try a nice pair of 300ohm or higher, you don't have to buy it just see if it corrects the problem.
Buy a cheap low impedance pair and wire a resistor(s) into them. Just put it onto the ground wire. Say if you want 600 ohms, and your headphones are 32, get a resistor of value around 500 ohms (if there is a 568 ohm one then go for it!) They are cheap as chips and you can just unsolder it if it doesnt work out.
I'm technologically impaired when it comes to electronics (I can help you with your chemistry questions though :? ). Can someone explain what impedence is, and what's the difference between high and low? For the gnx3k and computer headphone jack, which would I want?
basically impedance is the total opposition to current flow in an AC circuit. Capacitors and inductors behave differently as the applied frequency changes. So as the frequency changes the relationship between the voltage and current change. Resistors don't care about frequency.
In the case you are asking about, a higher impedance offers less load (somethng that draws current) to the source. For example my volt meter has a high input impedance, so hooking my meter into the circuit does not change the characteristics of the circuit, ie it does not draw any current from the circuit.
this link is pretty good. There are some math formulas but if you can balance a chemical reaction, you should be able to follow along.

How about a level control after your amp. http://www.rolls.com/new/frame2.html
Or down the road a personal monitor mixer - see other products.
