How does Odysseus and his men avoid being enchanted by the songs of the Seirenes?

Odysseus was a clever man. He wanted to pass by the Sirens with the boat, but he also wanted to hear the melody of the Sirens.

So he came up with this idea : He told his men to put wax into their ears, so they couldn't hear the Sirens singing, but he asked them to tie him with a rope to the mast, so that he could listen and enjoy the melody, but not be afraid to be enchanted and leave the boat.

So, while Odysseus was driven crazy, tied to the mast, his men sailed the boat safely far away past the Sirens.
