IPX6 Waterproof: Adventure-Proof, Rain or Shine

Life’s adventures don’t pause for rain, and neither does the D300. Its IPX6 waterproof rating laughs off pool splashes, beach waves, or sudden showers. Lounge by the lake, hike through a drizzle, or grill by the river—your music stays loud, proud, and waterproof.

20-Hour Soundtrack + On-The-Go Charging: Power That Keeps Up

A single charge fuels 20 hours of nonstop music at 50% volume (with bass and lights off). That’s a full day of beach trips, backyard gatherings, or solo hikes without a battery worry. And when your phone needs juice? The built-in USB-A port lets you charge your device on the move.

Wireless Stereo Pairing: Double the Speakers, Double the Immersion

Want to turn your space into a concert venue? Pair two D300 speakers with one tap for a wireless stereo system. Independent left and right channels flood your yard, deck, or living room with balanced, theater-like sound—no wires, no fuss. Double the sound, double the fun.

Beat-Driven Lights: Your Party’s Visual Rhythm

Let the music show itself. The D300’s built-in LED lights sync to every bass drop, pulsing and changing colors in perfect time with the beat. Whether it’s a rave-worthy bash or a cozy night in, the lights transform any space into a visual spectacle that matches the music’s energy.

Bluetooth 5.4 + USB Playback: Seamless Streaming, Everywhere

With Bluetooth 5.4, enjoy a stable connection up to 82 feet away—stream playlists without skips or interruptions. Prefer a USB drive? The D300 supports USB flash drive playback (drive not included) for even more listening flexibility.

Built to Go Anywhere: Portable Power for Every Journey

Lightweight and equipped with a built-in carrying handle, the D300 is made for life on the move. Take it to hiking trails, festival crowds, or a quiet riverside spot—your soundtrack goes wherever you do.
