JBL Boombox 4 VS LG XBoom Stage 301

Despite occupying nearly identical overall volumes (both just under 29,000 cm³), the JBL Boombox 4 and LG XBoom Stage 301 take fundamentally different physical approaches. The Boombox 4 is built wide and low — 506.4 mm wide but only 212.9 mm deep — giving it a classic horizontal boombox silhouette that sits close to a surface. The XBoom Stage 301, by contrast, is more cubic and upright at 312.42 × 327.66 × 281.94 mm, which may suit tighter spaces or tabletop placement better. Both weigh in at the heavy end — 5,890 g versus 6,169 g — so neither is designed for easy portability; the weight difference is negligible in practice.

The most consequential design difference is water protection. The Boombox 4 carries an IP68 rating, meaning it is fully dustproof and can be submerged in water beyond 1 meter — making it genuinely pool- or beach-ready. The XBoom Stage 301 is rated only IPX4, which covers splashes and sweat but nothing more. For outdoor or wet-environment use, this is a significant gap. On the other hand, the XBoom Stage 301 includes RGB lighting, which the Boombox 4 lacks entirely — a clear aesthetic advantage for party or ambient-lighting scenarios. Its larger 165 mm built-in subwoofer (versus 127 mm on the Boombox 4) also hints at a design philosophy that prioritizes low-frequency output within the same cabinet volume.

Overall, the JBL Boombox 4 holds a clear edge for rugged, outdoor-oriented design thanks to its superior IP68 protection and lower profile form factor. The LG XBoom Stage 301 trades that durability for visual flair and a larger subwoofer driver, making it better suited for indoor entertainment settings where weather resistance is a non-issue.

The raw power figures alone tell a striking story: the JBL Boombox 4 delivers 4 × 200W of audio output — 800W total — while the LG XBoom Stage 301 produces just 3 × 40W (120W total). That is a more than sixfold difference in rated output power, which in practice translates to dramatically higher maximum volume levels and greater headroom before distortion sets in. For large outdoor gatherings or filling a big room, the Boombox 4 operates in an entirely different class of loudness.

Speaker configuration reinforces this gap. The Boombox 4 features stereo speakers and a dedicated subwoofer, meaning bass, midrange, and treble are handled by purpose-built drivers with proper channel separation — a setup that produces spatial depth and punchier low-end. The XBoom Stage 301 lists neither stereo speakers nor a subwoofer in this spec group, which is a notable contrast given its larger physical subwoofer driver noted in the design specs. On frequency range, however, the LG edges narrowly ahead at the low end: 20 Hz versus 37 Hz for the Boombox 4, meaning the XBoom Stage 301 theoretically reaches deeper into sub-bass territory — though the real-world audibility of this difference depends heavily on driver performance.

The JBL Boombox 4 holds a commanding advantage in this category. Its combination of massively higher output power and a proper stereo-plus-subwoofer configuration makes it the clear choice for listeners who prioritize volume, spatial soundstage, and dynamic range. The XBoom Stage 301's slightly wider frequency floor is an interesting data point but is far outweighed by the Boombox 4's structural and power advantages.

Battery capacity is nearly identical between these two speakers — 4,584 mAh for the JBL Boombox 4 versus 4,700 mAh for the LG XBoom Stage 301 — yet their real-world battery life diverges dramatically. The Boombox 4 is rated for an exceptional 34 hours of playback, while the XBoom Stage 301 manages just 12 hours. This near-threefold difference from a near-identical cell strongly suggests that the Boombox 4 operates at significantly lower average power draw, which aligns with its much lower total amplifier wattage relative to the XBoom's configuration.

Charging efficiency also favors the Boombox 4. It replenishes fully in 2 hours compared to 3 hours for the XBoom Stage 301 — meaning not only does the JBL last far longer per charge, it also gets back to full capacity faster. For extended outdoor use or situations where access to power is limited, this combination is a meaningful practical advantage. Both speakers share the same baseline conveniences: a battery level indicator, a rechargeable non-removable cell, and no wireless charging.

The JBL Boombox 4 wins this category decisively. A 34-hour battery life that charges in 2 hours is genuinely class-leading for a speaker of this size, and the XBoom Stage 301's 12-hour runtime — while adequate for a day's use — simply cannot compete for multi-day or high-endurance scenarios.

Connectivity is strikingly similar across both speakers, with a few meaningful distinctions worth unpacking. Both share a 10 m Bluetooth range, a single USB Type-C port, and support for Auracast — a Bluetooth broadcast feature that allows one source to stream simultaneously to multiple listeners or speakers, which is a forward-looking addition neither competitor commonly includes at this price tier. Neither device offers Wi-Fi, AUX input, or a 3.5mm jack, so wireless Bluetooth is the sole audio transmission path for both.

Where they diverge is in Bluetooth version and codec support. The JBL Boombox 4 runs Bluetooth 5.4, the newer standard, which brings marginal improvements in connection stability and efficiency over the Bluetooth 5.3 found in the LG XBoom Stage 301. More practically relevant is that the XBoom Stage 301 supports AAC, while the Boombox 4 does not — meaning Apple device users streaming via the LG will benefit from a higher-quality compressed audio codec rather than falling back to the baseline SBC codec. Neither speaker supports any of the higher-fidelity codecs such as aptX, LDAC, or aptX Adaptive.

This category is essentially a near-tie, with each product holding one advantage over the other. The Boombox 4 offers a marginally newer Bluetooth version, while the XBoom Stage 301's AAC support makes it a noticeably better pairing for iOS and macOS users. For everyone else, the connectivity experience is functionally identical.

Across every feature data point provided, the JBL Boombox 4 and LG XBoom Stage 301 are a perfect match. Both support wireless operation and remote smartphone control, meaning users can manage playback from their phone without touching the speaker — a standard but welcome convenience for a device of this size. Both also include voice prompts and a sleep timer, rounding out a functionally identical feature set.

This is a complete tie. Based strictly on the provided specs, there is no differentiator in this category that favors either product — every listed capability is shared equally between the two.

This category comes down to a single but genuinely useful differentiator: stereo pairing. The LG XBoom Stage 301 supports pairing two units together for true stereo sound, while the JBL Boombox 4 does not. For users who own — or plan to own — two of the same speaker, this capability allows one unit to handle the left channel and the other the right, creating a spatially separated soundstage that a single speaker physically cannot replicate. It is a feature that meaningfully expands the LG's versatility in home or event setups.

The LG XBoom Stage 301 takes a clear edge here. While this is the only data point in this group, it is not a trivial one — stereo pairing is a deliberate design choice that adds real value for users willing to invest in a two-speaker setup.
