It will work if you use an adapter. You can buy the adapters online or at radio shack. they run about 3 dollars. It works great with my Palm 755.

It work with 3.5mm jack. Although you can use an adapter but at this price, try Sony in-ear heaphones... they are really good.

NO! 100 times NO. The jack in reality looks NOTHING like the photo. It's fat and oval shaped.
