I use these with the Sansa m250. I find they are both tough as nails.



I found the earbuds early last summer along the highway (we all find stuff, don't we?).
When these break--all earbuds eventually break, some sooner than others, but these have been particularly robust--I'll up for another set.

For a good seal, a little before insertion does the deal.



Regarding the mp3 gizmo (its two-years old at this point), this one has an armband/pouch that I use to tuck it inside my left arm, and all its functions can be accessed without looking at it, once one memorizes the steps (like effing with the bass equalizer setting/s as needed). Essential in my book.

And, it's pure drag-and-drop, so no funky software nonsense.

I do wish it could scroll within a particular file, but it doesn't. Otherwise it's good.

An Eveready rechargable can make it go the whole day too.
