Sirens were goddesses that trapped men on their island by singing. But Circe told Odysseus that he had to avoid their singing to get to his destination. She told him that his men had to put beeswax in their ears. Odysseus had to listen to the singing though.
Odysseuss: Quick tie me up and put beeswax in your ears and don't listen to anything i say while we are here
Odysseus: Their voices are so beautiful, we should go sing with them
Odysseus men didn't listen to him and they made it out safely
Odysseus men untied him and he thanked them for their service
Odysseus and his men sailed off to their next journey!
