FAQs

How does the AI Sound Boost actually improve the audio quality?
The AI Sound Boost uses a sophisticated algorithm to predict speaker movement and power response in real-time. This allows the speaker to push its drivers to their absolute limit safely, resulting in a much wider dynamic range and more powerful bass than standard portable speakers.

Is the 34-hour battery life guaranteed even at high volumes?
Playtime depends on volume levels and music content. The "28+6" hour estimate is based on moderate volume levels. Using the Playtime Boost feature optimizes the performance to stretch the battery life when you need those extra few hours of music.

Can I use the Boombox 4 as a power bank for my phone?
Yes, like previous premium JBL models, the Boombox 4 features a power-out port, allowing you to charge your smartphones or tablets directly from the speaker's massive internal battery so you never lose your music source.

What is the advantage of the IP68 rating over older IPX7 models?
While IPX7 only protected against water, the IP68 rating means the Boombox 4 is also completely "dust-tight." This makes it much more durable for use in sandy environments (like beaches) or dusty outdoor trails without risking internal damage.

Can I connect my older JBL speakers to the Boombox 4?
The Boombox 4 uses Auracast™ technology for the most stable multi-speaker connection. While it works seamlessly with other Auracast-enabled devices, you can also use the JBL Portable app to check compatibility and link with various speakers in the JBL ecosystem.

Customer Reviews

Based on 2576 reviews.

"I was a bit skeptical about buying a refurbished iPhone initially, but I’m so glad I did. I ordered an iPhone 13 in 'Excellent' condition and it arrived looking brand new—not a single scratch. The battery health is at 94%, which is a steal for the price. Fast shipping too, it arrived in just 24 hours."

"Picked up a MacBook Pro for university. The savings compared to buying new were huge. The laptop is clean and performs perfectly. The charger wasn't the original Apple one, but it works fine. Customer service was super helpful answering my questions about the warranty before I bought it."

"This is my third purchase from this store. This time I went for an Apple Watch. As always, the packaging was great (I love that it's eco-friendly) and the device works perfectly. It feels good to save money and make a sustainable choice for the planet at the same time. Keep it up!"

"Bought an iPhone 12 for my son. I chose the 'Good' condition to save some money. There are a few tiny scuffs on the side, but once the case is on, you can't see them at all. The screen is flawless and the phone runs smoothly. Highly recommended."

"Top-notch customer service. The phone I ordered had a minor audio glitch (these things happen with used tech), but they replaced it in record time without charging me for return shipping. You really see a company's true colors when there is an issue to fix. great job."

"Unbeatable value for money. I was looking for an iPad for work and found the best deal here. The tablet looks like it just came out of the factory. I really appreciate the transparency regarding the aesthetic grades described on the site; it matched exactly what arrived."

"Ordered an iPhone 14 Pro Max. Honestly, it’s spectacular. It came with a cable and the SIM tool. The battery life is amazing; I don't notice any difference from a new one, except for the much lower price tag. Will definitely be back for Christmas gifts."

"Reliable and intuitive website. I really appreciated the included 12-month warranty, it gives me peace of mind. The phone (iPhone 11) works great, no overheating and very responsive. Tracking was provided immediately and delivery was on time."

"I traded in my old device and upgraded to a refurbished one here. The trade-in process was simple and the valuation was fair. The new phone (Samsung Galaxy S22) arrived in impeccable condition. Very satisfied with the service."

"Everything was perfect, from browsing the site to the unboxing. The product was well-protected in the box. I tested the camera and microphone immediately, and everything is 100% functional. If you want quality tech without breaking the bank, this is the place."
