Powerful JBL Pro Sound with deep, punchy bass

The JBL Boombox 4 is engineered to deliver full-bodied sound with strong bass presence and clear high frequencies. Its redesigned acoustic system features two 5-inch woofers, two 0.75-inch tweeters and three passive radiators. Together, these components help reproduce music with impactful low frequencies, defined vocals and detailed high notes.

From bass-heavy playlists and dance music to pop, hip-hop, Afrobeats and everyday listening, the JBL Boombox 4 is designed to make music sound energetic and immersive. Its frequency response of 37Hz–20kHz gives you a broad audio range, while the speaker's output is designed to maintain a powerful, enjoyable presentation.

The speaker delivers different rated output depending on its power source:

• When connected to AC power: 2 × 65W RMS woofer output and 2 × 40W RMS tweeter output.

• When operating on battery: 2 × 60W RMS woofer output and 2 × 40W RMS tweeter output.

These figures describe the rated output of the individual driver groups. Actual listening results depend on the music, volume, placement and environment.

AI Sound Boost for powerful, controlled audio

Turn up your music with JBL AI Sound Boost. This technology analyses the audio signal in real time and adjusts the speaker's response to help deliver greater output while managing distortion.

This is particularly useful when listening to energetic tracks or enjoying music at higher volume levels. Instead of relying on bass alone, the speaker combines its acoustic design and real-time audio processing to help preserve a clear, powerful listening experience.

Choose your preferred bass with two Bass Boost modes

Different playlists call for different sound profiles. The JBL Boombox 4 includes two Bass Boost settings so you can choose the character that suits your music and mood.

• Deep Bass: Choose this mode when you want a deeper, fuller low-frequency presentation.

• Vibrant Punchy Bass: Choose this mode for a more energetic, punchy bass character.

Switch between the modes to suit your playlist, gathering or listening preference.

Up to 34 hours of playback

Keep your music going for longer with the JBL Boombox 4's rechargeable 99.02Wh lithium-ion battery pack. JBL specifies up to 28 hours of standard playback, with an additional six hours available through Playtime Boost, giving a combined maximum of up to 34 hours under suitable conditions.

Actual battery life varies with volume, audio content and usage conditions. Playing music loudly or using different audio settings may reduce the total listening time.

When it's time to recharge, the manufacturer specifies an approximate charging time of three hours. The speaker uses an AC power cable for charging.

IP68 waterproof and dustproof construction

Take your music beyond the living room. The JBL Boombox 4 has an IP68-rated design, offering a high level of protection against dust and water under the applicable test conditions.

This makes it suitable for many outdoor listening situations, including garden gatherings, picnics and trips where exposure to dust or splashes is a concern. However, water resistance is not a reason to handle the speaker carelessly. Follow JBL's care instructions, and avoid charging a wet speaker or exposing its ports to moisture.

Bluetooth 5.4 wireless connectivity

Pair the JBL Boombox 4 with a compatible smartphone, tablet or other Bluetooth audio source to stream music wirelessly. Bluetooth 5.4 supports convenient everyday wireless listening, while the speaker's A2DP 1.4 and AVRCP 1.6 profiles support audio streaming and compatible playback controls.

Enjoy your playlists without needing a wired audio connection between your phone and speaker. Wireless range and connection stability depend on the connected device, obstacles and surrounding radio interference.

Connect compatible speakers with Auracast

The JBL Boombox 4 supports JBL Auracast, allowing it to participate in compatible multi-speaker listening setups. Auracast-enabled speakers can be connected for a broader shared audio experience, depending on the devices and connection arrangement.

This feature is useful when you want compatible speakers to play audio together. Check the specifications of the other speaker and the manufacturer's instructions before purchasing for a particular multi-speaker setup.

Portable design for music on the move

The JBL Boombox 4 brings substantial sound performance into a portable enclosure with a built-in carry handle. It weighs approximately 5.89kg, making it portable for moving between rooms, taking to the garden or transporting to an outdoor gathering, although it is heavier than a compact pocket-size Bluetooth speaker.

Its approximate dimensions are 506.4 × 262.9 × 212.9mm. Consider these measurements if you intend to carry the speaker in a vehicle, store it on a shelf or take it on trips.

USB-C and powerbank functionality

The JBL Boombox 4 includes a USB-C connection and supports powerbank functionality. This can be useful when you want to use the speaker as part of your mobile entertainment setup and provide power to a compatible device.

USB-C availability does not mean every USB-C function is supported in every situation. Consult the manufacturer's instructions for supported charging, audio and device-compatibility details.

Lossless audio playback

JBL lists lossless audio playback among the Boombox 4's features. To take advantage of this capability, you need compatible lossless audio content and a supported app or service, together with the required connection method. Availability can depend on the source device, software and playback setup.

A more considered materials choice

The JBL Boombox 4 incorporates post-consumer recycled plastic and recycled fabric in its speaker grille. JBL also specifies FSC-certified paper packaging printed with soy ink. These material choices are part of the product's design and packaging approach.

Replaceable battery design

The JBL Boombox 4 is designed with a replaceable battery, offering a potential option for extending the speaker's usable life when its battery eventually needs replacement. The replacement battery is sold separately and is not listed as an included box item. Confirm compatible replacement parts and servicing arrangements before purchasing a replacement battery.
