You can use the JBL Xtreme 3 and JBL Xtreme 4 in every situation where you want to enjoy your favorite music. The speaker is waterproof, so you can take it with you to the beach, the pool, or the park without problems. That way, you can stream your favorite music anywhere. When it's dirty, you can rinse it with water. Thanks to the 24-hour battery life of the JBL Xtreme 4, you can listen to your favorite music for days. The Xtreme has passive radiators, so the bass sounds more powerful. You can easily take the speaker on the go with the included carrying strap.
