Which MP3 players are built to resist sweat and impact during exercise?
Almost all flash memory based MP3 players are suitable for use during exercise. Avoid the hard disk based players, though. Hard disks are not built to withstand constant movement. Sweat should not really be a problem, but if you’re concerned about that, you can buy a waterproof case for your MP3 player. You should also consider where to put your player during exercise. Some manufacturers offer special sports utilities. .
