Ultimate Ears Boom 3 Waterproof Portable Speaker – Night Black (Renewed)

Meet the Ultimate Ears Boom 3

Designed for everyday adventures, the Boom 3 blends bold, immersive sound with a compact, rugged form. In Night Black, the two‑tone fabric hides a speaker built to withstand splashes, with a soft touch that’s comfortable in hand and bag. This Renewed unit has undergone inspection to ensure reliable performance as you rediscover your playlists.

Rich sound for any space

BOOM 3 creates expansive 360‑degree sound with punchy bass and careful highs, so you can hear every note across a room or around a campfire circle. The tuning aims for balance, so vocals stay clear while low‑end depth remains present.

• Up to 15 hours of playback on a full charge for day trips or late‑night listening
• Optional POWER UP charging dock (sold separately) for wireless recharging, keeping the music going

Rugged and ready for outdoors

Waterproof and buoyant, BOOM 3 can float if dropped near water and is designed to survive life's inevitable splashes and bumps. The exterior uses a shimmering two‑tone fabric that combines durability with a premium feel.

• Waterproof up to 1 meter for 30 minutes
• Durable fabric and build suitable for travel, beach, or backyard gatherings
• FCC certified (FCC ID JNZS00170) for regulatory compliance

One‑tap control and seamless party mixing

Use the Magic Button to control playback on the fly, while PartyUp lets you wirelessly link 2, 3, 4, or more than 150 speakers across generations for larger gatherings.

Real‑life use cases

Imagine a sunlit porch, a rainy balcony, or a dorm room jam session. The Boom 3’s sound stays balanced with clear vocals and satisfying bass. Its portability and waterproof nature reduce worries about spills or wet hands when you reach for the controls.
