Unbeatable sound all day long.

We turn it up our way—anywhere.
The all-new JBL Boombox 4 is bigger, bolder, and better than ever, with powerful JBL Pro Sound that stays loud and clear, with deep thumping bass. AI Sound Boost analyzes our music in real time and adjusts the sound to give us more power with less distortion, even when we turn it all the way up. It packs two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. When we want to fine-tune the vibe, we just switch between deep or vibrant punchy Bass Boost settings to match our mood. We gave the classic Boombox design a fresh upgrade—it’s larger but lighter, so we can take it wherever the party goes: the beach, the block, or the backyard. It’s IP68 waterproof and dustproof, so weather’s never a dealbreaker. And, with up to 34 hours of playtime (thanks, Playtime Boost), we’re set for the long haul. With the JBL Boombox 4, we carry the mood and the energy, everywhere we go.

General Features

We’re talking massive sound with deep and punchy bass. The redesigned JBL Boombox 4 packs in two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. And with AI Sound Boost, we don’t have to lift a finger—this smart tech analyzes our music in real time and adjusts the sound to give us more power with less distortion, even when we turn it all the way up.

Keep the vibe alive from party to party... to party, for up to 28 hours on a single charge. Forgot to charge up for the next one? It’s all good. JBL Playtime Boost adds up to 6 hours of extra popping, locking, sliding, or whatever moves you got left in that bag.

The JBL Boombox 4 is IP68 waterproof and dustproof, so it can handle whatever the weather—or our clumsiest friends—throw at it.

Wouldn’t it be great to share the whole mood with the whole crew? With Auracast™, effortlessly stereo pair two Boombox 4 speakers for a wider sound stage or connect multiple Auracast™-enabled JBL speakers to cover more ground with the same playlist.

When it comes to bass, we like having options. Fire up the JBL Boombox 4 and you’ll get that classic JBL signature bass we all love. Want to take it deeper? Hit the Bass Boost button on the top panel—the JBL Horn mark glows orange, and boom, you’re in Deep Bass mode, where those two woofers and three passive radiators go all in. Want something tighter and more energetic? Tap the button twice, the Horn mark turns white, and you’re in Punchy Bass mode. Whatever the mood, we’ve got the bass to match.

The JBL Boombox 4 sounds bigger and better than ever—but here’s the real win: we redesigned it to be lighter than before. So now it’s way easier to set the tone wherever we go.

Want to hear every detail? Plug into your laptop or other audio device using the Boombox 4’s USB-C port* to enjoy lossless audio playback. It’s perfect for real audio fans who want more from their music. Just make sure your source offers lossless audio.
*Requires compatible lossless audio content from supported apps or services.

The JBL Boombox 4 incorporates post-consumer recycled plastic and recycled fabric for the speaker grille. It’s also packaged in FSC-certified paper printed with soy ink.

MUST READ BOOK!!
Format: Kindle
I was in a huge reading slump, when one of my favorite authors recommended this book in her readers group (The amazing Marie Mistry 🫶) and I absolutely DEVOURED this book. Now I’m in the club crying about having to wait until December for Term 2! This book is about a girl named Pandora who has suffered a life that nobody would ever wish to have. This book is about Pandora learning how to live, learning about herself and what she really wants. She has a long journey to find out all of these things, but she took the first steps in this book and it was beautiful to read. Some of the men in this book are our dream men, Hunter and Reed 😍 and then we have the men who need some work and who we all really just want to beat up until they admit what they really feel, Skel, Bram and Dexter. But that cliffy was a killer and I absolutely cannot wait until the next book!! You have written an absolute dream of a book Lyra and I eagerly await the next installment in this series!!!

Addicting!
Format: Kindle
I could not stop reading. It was so refreshing to have a series start so completely different than most fated mates/fantasy academy rh I’ve been reading. From the desert scenery to the magic and feeding plus the psychological trauma the characters are there to deal with. Pandora is absolutely adorable and I totally relate to hiding behind my hair. I love that she’s literally the most scary type of demon but it’s not the usual “badass mc” persona (which I do love a badass that can fend for herself and kick ass from the start but it was a nice change of pace). I’m not usually a big fan of bully within the harem but each character has their reasons for their actions and also conflicting feelings about them. I adore Dex and Reed! Complete opposites but their personalities and inner monologues made them instant favs. I can’t wait to see the character growth with the guys and continued strength for Pandora. The captivating characters and references to the Fate Hallow series added so much depth and now I need another reread while I wait for book 2. The concept of magic and the unique feeding habits of the demon characters were intriguing. I can't wait for the next book to continue this thrilling journey. In summary, this book is a must-read for fantasy and magic academy rh fans. With its enchanting characters, nods to the Fate Hallow series, and imaginative concepts, it offers an immersive reading experience that hwill leave you craving for more.

Best academy I've read this year
Format: Kindle
I need a few things when it comes to a first book of a PNR romance series 1-Good world building (which this totally did) 2-An FMC I can root for (oh hell yes, Pandora is someone I can cheer for) 3-Good drama (can you say GROVEL BOYS!) 4-Enough story to make you feel like you really read something with meat (you saw this book is like 600 pages, yeah?) 5-A hook at the end so I want more! (please, Lyra, gimmie more?!? I need more!!) Be aware this book is a slow burn, but damn do I feel like there'll be some big payoff when it finally happens. Who doesn't like the buildup?

Pandora’s Pain, Power, and Passion
Format: Kindle
I absolutely love this new world Lyra Winters has created! The spin on a Demon Academy setting was fresh, unique, and completely addictive. Pandora is a character who immediately captured my heart. Thought to be powerless and enduring years of brutal abuse from her mother, it’s no surprise that her powers emerge at the exact moment she needs them most. After her mother’s death, Pandora discovers her father is none other than Death himself, a soul eater with a dark legacy. Her journey at the academy is anything but easy, filled with challenges tied to her father’s infamous reputation, her barely controlled abilities, and the cruelty of those around her. Pandora is easy to root for, you feel every ounce of her pain, resilience, and growth. Along the way she meets Reed, a half-human dream demon who’s kind, steady, and the kind of friend everyone wishes they had. There’s also Hunter, a vengeance demon and counselor connected to her father, who adds another intriguing layer to her story. Then there are the bullies: Dexter, a brooding shadow demon; Bram, a chaos demon with a drinking problem and deep hatred for demon nobility; and Skel, a fear demon wrestling with his own darkness. They might hurt her, but they also can’t seem to stay away when she’s in danger, making for some deliciously complicated dynamics. This book hits so many of my favorite tropes: friends to lovers, enemies to lovers, and of course, the irresistible “who hurt you?” storyline. I devoured it, and I’m already diving straight into book two!

So good!
Format: Kindle
Oh my goodness! What did I just read? Lyra Winters you have some serious explaining to do! That cliffhanger killed me! I am so happy to be back in the world of Kalista. This is definitely darker than Fates Hollow but oh so good. This is a fated mates reverse harem which I absolutely love. Pandora had a very hard and rough upbringing. She lives in pain constantly and it makes it hard on her. She struggles with everything because she was kept so isolated and is new to her magic. Pandora gets sent to the Reform Academy and all of them have reasons why they are there. I love how, after everything she has been through, she is still a nice person. She is growing and becoming stronger too. Love her character. The guys all act like jerks at first but all have a back story that helps understand why even though want to smack them. I'm here for the groveling that I'm sure will come. I love them all. They each bring something for her. They are all drawn to her though. This is a slow burn book but there will be more books in the series so sure it will build. Man, that cliffhanger was a doozy and need book 2 now!
