This Cyber Monday deal isn’t just for an Ultimate Ears waterproof speaker

Now, the Ultimate Ears Boom 3 may be waterproof with an IP67 rating. But it also undergoes serious durability testing that includes testing for submersion at up to 1 meter of water for up to 30 minutes. Coupled with 15-hour battery life, 360-degree sound, and four EQ modes, the original price is already a good deal. But Ultimate Ears also couples this Cyber Monday-ready speaker with the Ultimate Ears app for “Partyup” mode. That means this speaker can be paired with up to and over 150 other Ultimate Ears-branded speakers. So buyers can get even bigger sound from the two 2-inch drivers and two 2-inch by 4-inch passive radiators. And, of course, these speakers are also designed to float. So regardless of whether the Night Black, Lagoon Blue, or Sunset Red variants are bought — the Ultraviolet Purple variant is not on sale, unfortunately — they can handle falling in the pool or lake without being lost in the depths. As added icing on that already great cake, up to 8 Bluetooth-enabled source devices can be paired. With up to two source devices at the same time. So more than one person can help keep control of the audio playback as needed. All without interrupting the flow of whatever gathering the speakers are being used for.
