The ULT button on the speaker provides an even deeper bass and fuller sound, so you can completely immerse yourself in your music. The speaker has an IP67 certification, so it's dustproof and water-resistant, so you can take it with you to the beach or pool without issues. The speaker is shockproof, so it can take a hit.
