I have x50mix but its bothersome juggling btw its settings and the native settings in Mortplayer and TCPMP so most of the time I don't bother with it. Sometimes the hissing appears when the pre-amp setting is turned up too high, but I don't have it otherwise.
This should let you continue using whatever low-impedance headphones you want, but block off the noise.
I have decent ($109 Westone UM1) low-impedance IEMs, and that would be the best solution for me...but I don't mind the hiss, so i'll be frugal and save 10 bucks =)
I have great hearing, and I hear zero hiss with TCPMP. Maybe you need better headphones.
Suggestion for the peeps that are saying TCPMP is too loud: Try mapping whatever button you use for volume to control fine volume instead of regular volume, it takes smaller steps, so your minimum volume is much quieter. Also, I have it set up so that my main volume is independent of TCPMP's volume, and I keep it at about 50% when listening with headphones. I think you'll find this works pretty well.
I have UM1, k81dj and ksc75. Of these, the hiss is only apparent with UM1 and only when no music is playing. I'm using mortplayer and tcpmp. I found that using a resistor in the line cuts down practically all of the hiss. I had 2 built, one 50ohm, one 75ohm.

pardon the n00bness, but how does one build an in-line resistor for a earphone?
Also, if you do a search on hiss in this forum, you'll notice a guy posting in all the threads that using a 32 ohm earphone instead of a 16 ohm one solves the problem. Is he right?
Basically, the higher the resistance, the less hiss you get. Just don't put too big a load in the line or else your ax won't be able to drive your earphones properly as it takes up too much power.
I just build a short length of extension cable, about a couple inches long, with a male plug on one end and female on the other. Then I just solder a resistor to each signal bridging the cable and the female plug. Since its so small, the whole thing fits into the barrel of the female plug so you can't see anything at all.
You could get a Shure or a Ultimate Ears attenuator to save the trouble, but the shure one has a bulky volume control pod and the load is very heavy, 250ohm in each channel. The UE one is a nice looking solid plug, but the lack of flexibility may cause stress on the headphone jack if you yank it accidently. My solution only cost a couple bucks for the DIY parts.
for everyone who is saying there is no hiss, maybe you need to get your ears cleaned. I'm not trying to be insulting, that's exactly what I did. Before I went to the ear nose and throat doctor to get a ton of wax taken out, I thought there was no hiss in my Creative ep-630's plugged into x51v. After I left the doctor's, i could hear everything so much better, and noticed the hiss for the first time. Also, before any of you flame me and say you have "great hearing", note that I felt the same way even BEFORE i went to the doctors. It's just that when I came out, my hearing was 10 times better. I couldn't even take a shower for like 2 days because the noise was just so loud.
This hiss occurs everywhere, including mp3 players and my friend's HP4700 pocket pc. It's independent of the volume. Same noise level hiss at every volume level. Of course the hiss goes away if I turn all sound off.
I just bought a pair of Creative Aurvanas (42 ohm) and I Hope it gets rid of it. For the impedance thing, I tried it with my friend's $9 TDK CP-100 headphones, which are 16 ohm. No hiss whatsoever. Weird huh? I highly doubt it's my EP-630's that are the problem, though. Look online for reviews and they are all highly positive. Maybe it's because I had wax taken out like 2 weeks earlier so I'm the only one that hears this hiss. But it is loud as hell, almost like a fan 5 feet away from your head.

would you like to post some pictures of how you DIYed your attenuator? =P
It hisses every time it plays audio. When it's sitting on the today screen doing nothing, i'm guessing the audio chip isn't active. When a sound is played, like even the click sound of the start menu, it hisses after the click maybe for half a second, until the audio chip stops outputting completely. I don't think it's a solvable thing; I think it's just the chip we have. Quality is still quite good hiss withholding, so no worries there (for me, as long as music is playing i'm happy).
I have decent earphones in Westone UM1s as well.
For all you guys complaining about the "noisy" audio on your Axim, have you ever plugged headphones into a laptop? My laptop is 10x worse than my Axim -- if you have it turned up you can hear noise from the chipset, the cpu, the hard drive; even when you move the mouse around the screen. At work I use my axim to listen to music rather than the laptop for just this reason.
Yes, there is a small amount of noise present in the Axim's audio subsystem. But it is a MINOR thing, lets not go nuts over it.

Norseman, I tried my friend's Creative Aurvanas (42 ohm). The hiss on my axim (as well as all other portable players) is the same as with my 16 ohm creative ep-630's. When I plug my ep-630's into my harmon kardon pc speakers there's no hiss. When I plug the aurvanas in there, there is a hiss that IS proportional to the volume. From this one experience, I would conclude that if anything, higher resistance does nothing for the hiss, if not makes it outright worse!

You also have to factor in the isolation provided by the headphones - the Aurvanas probably isolate more than the ep-630s and therefore the hiss is more audible.
Have you tried plugging them both directly to the source? Maybe the speakers have additional circuitry that comes into play, I have no idea. My (limited) experience comes from using laptop/dap/pda --->cable--->headphones.
