Travel Carrying Strap for JBL Boombox 3 Waterproof Portable Bluetooth Speaker, TXEsign Shoulder Strap with Two Side Covers Travel Carrying Pouch for JBL Boombox 3(Black)

Product Information

It’s a portable speaker that can deliver a massive sound, and it delivers it well. The audio is crisp, clean, and precise and the bass booms. The battery lasts a massive 24 hours, and the IP67-resistant design allows you to take the speaker anywhere without worrying about it. The Boombox 3 boasts a very similar design to the Boombox 2. The only immediate difference is the handle. It’s now a metal handle with silicone grips that sits on top of the speaker instead of blending into the ends like on the Boombox 2. It looks good. We managed around 22 hours of use before needing to recharge the speaker. This was close to the maximum volume as well. As far as the comparison with Tribit’s challenger named Stormbox Blast was concerned, the first thing that amazed us was the Stormbox Blast’s tight performance for a significantly lower price – at least at moderate volume. Vocals sounded as pleasingly natural over both, and both also offered an exceedingly rich bass. But at medium levels, the JBL Boombox 3 seemed to ignite a kind of booster and set itself further and further apart as the volume increased. Quite obviously, JBL is not simply getting paid for the name here. There’s also a lot of oomph behind it.

To ensure this, the new JBL Boombox 3 has a particularly robust design. The JBL Boombox 3 is IP67 certified and therefore resistant to water and dust, so in principle it can be used in any environment and in all weather conditions. It’s not surprising that the Boombox 3 is power-hungry and requires a mains connection for battery charging as well as for maximum power operation. Nevertheless, it needs a whopping 6.5 hours until an empty battery is full again. JBL provides specs for both AC and battery modes. If you plug it into AC, you get 80 watts (W) for the sub, 40W for the midrange drivers, and 10W for each of the tweeters. On battery, power decreases slightly: 60W for the sub, 30W for the midrange drivers, and 8W for each tweeter. Meanwhile, the subwoofer expands the frequency range to 40Hz-20KHz (up from 50Hz-20KHz on the previous model). As we discuss later, this additional range makes an appreciable difference. The bass capabilities are impressive, delivering powerful and clean lower frequencies without sounding distorted. Midrange and high frequencies also sound clean. A weakness of a lot of portable speakers is the audio starts to sound tinny at higher volumes. The Boombox 3 does an excellent job of keeping the sound well-balanced and precise throughout the volume spectrum.Though it costs more than Tribit's Stormbox Blast, the 11.7-pound Rave Party 2 is a more attractively designed speaker and arguably sounds slightly better. Its two 4-inch woofers and two 2-inch tweeters deliver aggressive, punchy sound with enough volume to fill larger rooms (the Tribit's bass goes a little deeper, but I was pretty satisfied with this speaker's low-end capabilities). For even bigger sound, you can wirelessly link multiple Rave Party 2 and other Soundcore speakers that support the company's PartyCast 2.0 feature.

The Boombox 3 boasts an IP67 resistance rating, meaning the speaker is waterproof. It will survive being submerged in up to 1m of water for 30 minutes and is protected from dust. This means you can take it to the beach, use it at a pool party or wash it off in the sink without worrying about it getting damaged. There’s an equaliser, a user guide and a PartyBoost option. PartyBoost is JBL’s software that allows you to connect up to 100 different speakers wirelessly. It’s easy and works well. Once again, the new JBL Boombox 3 is said to be characterised by particularly rich sound, whereby the manufacturer speaks of an even more powerful performance than the previous generation. JBL Boombox 3 with JBL Original Pro Sound On the contrary: Its subwoofer seemed to really get going when the volume control was turned halfway up and pushed more and more vehemently up to a certain point as the level increased. The punch was very rich, just the way you like it with dance music beats. At the upper end of the transmission range, the JBL Boombox 3 produced fresh, but by no means sharp highs. Cymbals and other high-frequency impulses not only flashed magnificently. They also had a pleasant effortlessness about them. Freedom with the equalizerThe Boombox 3 is compatible with Bluetooth 5.3 and supports the SBC codec, but not AAC or AptX. Sonic fidelity is less important outdoors, but we expect higher-end codec support in light of the premium price. Again, this doesn't really affect the powerful bass or impressive volume output, but anything to help with audio clarity over Bluetooth is welcome.
