What setup should I get for under 300$?

Hi everyone I'm new to these forums and am a general newbie with this stuff so any and all help would be greatly appreciated. I'm looking to get a setup for around 300$, nothing too crazy. A mp3 player, an amp, and some headphones, and maybe a cool dock cable or something. Looking around myself I've come up with some ideas but I'm not sure. I was looking at maybe a sansa fuze then buying a sd card which should run my about 75$. I saw a Fiio e7 amp for around 100$. And then I was looking at maybe getting a pair of sony mdr-v700 headphones for like 90$. Any suggestions for comments?

thanks for the advice,  for headphones I wanted over the ear headphones not in the ear ones, I would like something that doesn't leak a lot of sound and I would like them to have some good bass.  As for the source, I'm not too picky I don't really need touch screen, videos are a plus but not needed, I rather something that sounds good and play flac. I would like it to be reasonably portable, and yes by 300$ I meant U.S dollars. So basically whats the best setup I can get for under 300$. I've seen those little Fiio E5 for 20 bucks but I wonder how much it really does. Any other opinions?

Thank you so much for your advice. yea I was leaning towards getting a Fuze, It seems pretty good way to get started for the price. I like the idea of longer battery life and possibly videos over the clip but I read somewhere that it can't take the same sdhc card which confused me. I also like that it has a LO, but apparently not a "true" one. I could get that for around 75$ so that leaves me another 200$ or so. What are some good headphones options for around 100-150$ that wont leak much?  finally an amp around 100$ as well, something like the Fiio E7, ibasso t4, nuforce icon mobile, or mabye a Garys PA2V2 amp I seem to hear a lot about on these forums, anybody have some insight to which is better? Thanks again any and all opinions are welcome :)

I  should have mentioned I would be using the amp/dac for my computer as well if I got it, quite a bit actually when I'm home, then take it with me to go with my mp3 player, I would probably end up listening to it more from my computer then anything now that I think about it. But either way any suggestions on headphones then? Like I said I'm willing to spend more than 100$ U.S on a set, nothing too expensive though. I read so many reviews but always seem to get mixed results. Definitely think I'm going with a fuze, so that much I have decided. I'm about to order one then get the headphones next, I just don't want to get an expensive pair of phones that won't live up to their expectations without an amp then I gotta go buy an amp and I just end up spending too much. But like I said all advice and opinions are welcome. I was hoping to hear from some people who have tried various headphones and get their opinion on them, that link to thread comparing the headphones was helpful but I didn't quite find a pair that fit into my genre.

Yea I should mention I am small and have a small head so I don't want anything too large and it needs to be semi-portable, thanks though I'll look into them.

I've been looking into ath-m50s which I seem to hear good things about and can be found for a pretty good price, I wonder though is it worth it to go for something just a little more expensive like the hd-25 II mentioned before?

honestly I don't see much not to like about them at all, they along with a few other pairs fit my needs pretty well. I just wonder if there was any another pair for cheaper that had better or equal sound quality for less money before I commit to buying. I'm really starting to lean towards the hd-25s to be honest. How are they in terms of comfort? Are there any cons you can think of? Out of curiosity exactly what setup do you currently have Hero Kid? Thanks again for your input BTW.
