Soundcore Boom 3i Portable Bluetooth Speaker

The Soundcore Boom 3i isn’t just another rugged Bluetooth speaker—it’s designed for people who actually take their music outdoors. Whether you’re floating down a river, hosting a pool party, or setting up camp by the beach, this speaker stays loud, clear, and upright no matter what the environment throws at it.

Industry-First Floating Playback

What really sets the Boom 3i apart is its floating, sound-forward design. Even in moving water, it stays upright so the audio doesn’t get muffled or distorted. No sinking. No flipping. Just consistent sound while kayaking, swimming, or relaxing in the pool.

Powerful 50W Sound with BassUp™ 2.0

Don’t let the compact size fool you. With 50W output, BassUp™ 2.0, and advanced DSP tuning, the Boom 3i delivers deep bass down to 56Hz with clean mids and crisp highs. It’s punchy enough for outdoor gatherings and clear enough to enjoy detailed music, even in open spaces.

IP68 Waterproof & Built for Saltwater

This speaker is IP68 waterproof and dustproof, meaning it’s fully protected against water, sand, and dirt. It also goes a step further with 5× saltwater resistance, making it perfect for beach trips, boat rides, and sweaty summer days—without worrying about rust or corrosion.

Tough, Travel-Ready Design

The Boom 3i is made to take hits. It’s drop-tested from 1 meter, weighs 780g, and includes a detachable strap for easy carrying. From camping trips to picnic setups, it’s built for movement and rough use.

Smart Features & All-Day Playtime

With up to 16 hours of battery life, the music doesn’t stop early. Through the Soundcore app, you also get access to smart features like:

Voice Amplifier for clear announcements
Emergency Alarm for safety situations
Buzz Clean to shake out trapped water

Plus, Bluetooth 5.3 ensures a stable connection, and TWS pairing lets you connect two Boom 3i speakers for a wider, louder soundstage.

If you want a floating Bluetooth speaker that’s loud, durable, waterproof, and actually designed for real outdoor use, the Soundcore Boom 3i checks every box. It’s a true adventure speaker—ready for water, weather, and whatever comes next.
