The Sony SRS-XV500 is a party speaker with a powerful sound and long battery life. It is IPX4 rated, which means it can withstand splashes and spills. The speaker has a built-in light show which can be customised using the Sony Music Center app. However, the speaker does not have an optical port, so it cannot be used as a soundbar for a TV. Overall, the Sony SRS-XV500 is a good option for people who are looking for a portable speaker with a powerful sound. However, the lack of an optical port may be a dealbreaker for some people.
