frustrated headphones

The phones that SanDisk provides with its players are ok enough, especially as an accessory, but much better phones, including at low prices, are available.  (And note that it is unlikely that SanDisk itself makes the phones–rather, it likely buys large quantities of them from a Chinese manufacturer.)  Sources like anythingbutipod.com and its forum can lead you to good options–there is a headphone sub-forum there.  .
