The sticks, Sony's attempt at a universal, portable storage medium for everything from cameras to computers, only work with properly equipped computers and peripherals. As you can see, the cost of the player isn't your only concern. If you don't want to be copying your favorite songs every time you want to listen to them, you'll need some sort of memory expansion option. Thus, when considering the cost of a player, consider how much it'll cost to add more storage, either now or in the future. Power to the people and big name sound The final two components to consider are battery life and the fidelity of the headphones included with each player.
Some players run off of rechargeable lithium batteries.
Some have car lighter adapters, others have DC input jacks. Just like any portable stereo, though, you'll eventually have to change the batteries. Expect about eight to 10 hours of play per charge. Some players claim more, but if you expect a battery swap for every eight hours you listen, you probably won't be far off. Some players, especially those using primarily built-in memory, can be sensitive if you don't change the batteries relatively soon after they die.
