Not all speakers are created equal. Some can provide the soundtrack to your life while taking on dust, dirt, and rain. Emberton III does exactly that and more. It’s not for display, it’s there to join the party, wherever the party ends up. You can chuck it in a bag, throw it in the back seat of your car, take it on a cross-country ride, or hit the beach, completely stress free. Emberton III is ready for the fast lane. While you’re busy living life to the fullest, you’ll experience absolute 360° sound. True Stereophonic is a unique form of multi-directional sound from Marshall – where every spot is a sweet spot. No matter where you’re standing, the music will sound vibrant, balanced and loud. Just like it should. With 32+ hours of portable playtime, and battery preservation features built for almost endless listening sessions, you can keep the music playing on repeat. We’ve also updated Emberton III’s design to make it more straightforward and convenient to use while staying true to its rock ’n’ roll heritage. The classic grill, textured sleeve and iconic Marshall script hark back to our legendary amps with the added benefit of a built-in mic. Emberton III will go the distance and back again.

The soundtrack to our life, right in the palm of our hands. The JBL Flip 7 is undefeated JBL sound that travels with us wherever we go. Because music has no boundaries, and neither should we. Whether we're hosting a beach party, relaxing in our backyard, or setting the mood for a cozy night in, the Flip 7 is designed to enhance any experience, anywhere life takes us. And now, our signature sound is bigger and bolder than ever, thanks to JBL's AI Sound Boost. The end result? The Flip 7 leaves our friends and family wondering where all that big, glorious sound could possibly be coming from. But it's not just pretty and powerful. The Flip 7 takes a beating without missing a beat, boasting industry-leading IP68 waterproof, dustproof and drop-proof. Plus, with new Playtime Boost we can enjoy up to 16 hours of playtime—because the moment should only ever stop on our terms. Wouldn't it be great to share the sweet sound of JBL far and wide? Now we can. Effortlessly connect with other Auracast-enabled JBL speakers to cover more ground (and more ears) with the same playlist, whether we're touring the town with our cycling crew or extending our dinner party to the back patio... and the front yard. In short, this is not the average portable speaker. It's a pint-sized audio boss.

Cue the connection with the back and better-than-ever SoundLink Micro (2nd Gen). Deceivingly small, this portable powerhouse can fit in the palm of your hand, yet still deliver up to 12 hours¹ of crisp sound. Powerful enough to break any silence, anywhere.
