"SlimX is one of the few new generation portable players that I have seen which has some beef in its headphone out. At 12mW per channel, the player should have no problem driving almost all ear buds and many phones to earsplitting levels. Most portable players today have a headphone out of between 3mW - 7mW so that manufacturers can squeeze as much battery life as possible." ~ T-Break
