I've been having intermittent problems with what I *think* is the audio plug. I'm invoking my warranty and returning the X5 dell for a new unit.

However, I'd like to know what would be the optimal setup for playing MP3s. I don't expect iPod perfection, but I'd be ever so pleased if if I could listen to a song all the way through without losing sound in one ear.

So what are best things to have, as far as:

- OS versions and patches
- MP3 player
- headphones
- accessories
- anything else you can think of

If whoever has a setup that they've really found optimal, could you please list the details.

Thanks.

I've tried several different players and gone back and forth with formats (wmp or mp3) and here's what I'm using now:

Axim X5, with Windows Mobile 2003 (never patched or updated since Sep 2003.)
Player is GS Player which looks like it had a recent update to 2.0. I'm still using 1.96.
Format I use is mp3 at a 96 rate. 64 just didn't sound good enough in my car. 96 was the compromise between sound quality and storage quantity.
I use just the basic Sony walkman type headphones or a cassette adapter in my car. The cassette adapter was the standard Target/WalMart variety for less than $20. For longer trips I'll also plug the Axim into the car charger cable to keep it fully powered up.
Songs are stored on a 1gb CF card. I did have problems using wma files on the CF card, but mp3 has been fine (on the same card!)

This set up has worked for me.
