DOSS Extreme Boom+ Outdoor Bluetooth Speaker – 100W Stereo, IPX6, 20H Playtime, PartySync

Unleash Giant-Sized Sound Outdoors

The DOSS Extreme Boom+ packs 100W of stereo power into a rugged portable speaker. With dual 40W woofers, dual 10W tweeters, two passive radiators, and two DSP technologies, it balances deep bass with clear highs for outdoor listening that feels immersive.

In practice, the bass responds with authority as you raise the volume, while the treble stays crisp. Engaging Extra Bass Mode boosts low-end for larger spaces or louder gatherings, without compromising clarity. The passive radiators push air within the enclosure to deliver a fuller low end even in tighter setups.

Water-Ready, Weather-Ready, Anywhere-Ready

IPX6 waterproof design means rain, pool splashes, or a breezy beach day won’t derail your soundtrack. The speaker’s rugged construction is built for camping trips, backyard parties, and outdoor adventures, letting tunes follow you from sunup to sundown.

Light Up the Moment with Beat-Synced LEDs

The built-in LED system offers six modes that sync to your music. From breathing pulses to rippling waves and rolling patterns, the lights help create atmosphere that matches tempo and mood for any gathering.

Long-Lasting Power with Built-In Charging

A 10400mAh battery supports up to 20 hours of playback at moderate volume, with longer times possible at lower volume or without LED effects. A built-in USB-A port can charge a phone in a pinch. Pro tip: fully charge on receipt and use the M+O option to manage battery-saving modes if needed.

Scale Your Sound with PartySync

PartySync lets you pair two speakers or up to 100 Extreme Boom Pros for a bigger, wider soundstage. For intimate get-togethers or larger outdoor events, this feature helps you tailor the vibe while keeping setup simple. Bluetooth 5.3 keeps pairing fast within about 99 feet, with wired options via 3.5mm line-in or Micro SD for versatile playback.
