erm, Ive never actually heard an x5 so i cant really advise there. What I can say is that unless you want to go down the custom ear mold route, your spending is kind of limited. I would think that 100-200 USD would probably be a reasonable ammount, but it is very much the case that the more you spend, the more you get.
I think the conventional wisdom is to spend about 1/3 of your budget on source, 1/3 on amplification and 1/3 on speakers or headphones + a bit for cables and interconnects. I prefer to go 1/4 each on source and amp, then 1/2 on speakers/phones and use regular copper speaker cables/ homemade interconnects.
With regards to the stereo, you can either get an FM transmitter (crap) or a tape converter (crap). though if you haven't upgraded your car stereo in any way, it probably doesn't matter. On ballance, I would recomend the FM transmitter. they tend to be a bit less rubbish, and remove the need for cables.
