Not only do they hold the plug tighter, they hold the wiring in them tighter in most cases and, as you say, they hold up a lot longer than cheaper ones (which stop holding the plug pretty fast). In theory, a better physical connection means the power transfers better. Does that mean that it sounds better? I can't say, but for the price of them, the risk to reward is way on the positive side.
