Description
This is a portable Bluetooth speaker sold under the SOWO Audio name, in a cylindrical black body measuring 4.25 inches across by 9.8 inches high and weighing 1.59 pounds. The listing specifies a 3 inch woofer, a 1.5 inch tweeter, an IP67 rating, colored lighting, 12 hours of battery life, a 2.5 hour charge time, and an auxiliary input alongside Bluetooth. The box contains the speaker, an auxiliary audio cable, a hanging line, a USB-C charging cable and a manual.
One thing to note about the listing itself: the product title names no brand at all, describing the item generically as a wireless waterproof Bluetooth speaker. The manufacturer field gives SOWO Audio and the model number field simply reads “Portable Bluetooth Speaker”. That is characteristic of unbranded or lightly branded listings, and it is worth knowing before buying, because support and warranty on such products can be harder to pursue.
The Two-Way Driver Arrangement
This is the most interesting specification and it is uncommon in a speaker this size. The listing gives a 3 inch woofer and a separate 1.5 inch tweeter, which makes this a two-way design: one driver handles low and mid frequencies and a second handles highs.
Most portable speakers of this size use a single full range driver, sometimes with passive radiators for bass. A single driver has to reproduce everything, and physics makes that a compromise: a cone large enough to move air for bass is too heavy to respond quickly at high frequencies. Splitting the job across two drivers lets each work within its range. Whether the result sounds better depends on the crossover and the tuning, which the listing does not describe, but the arrangement itself is a real engineering choice rather than a marketing term.
The channel configuration is listed as 2.0. Note that a single speaker with one woofer and one tweeter is a mono two-way design regardless of what the channel field says, and the title’s reference to stereo sound should be read as marketing language unless the manufacturer confirms two separate channels. Signal to noise ratio is listed at 75 dB.
Water Protection and Battery
The title states IP67. That is a specific and useful rating: the 6 means complete dust protection, and the 7 means protection against temporary immersion in water to a depth of one meter for thirty minutes. Unlike an IPX rating, which leaves dust untested, IP67 covers both. For beach, poolside and camping use that is the rating you want, and it is stated clearly here rather than left as a vague waterproof claim.
Battery life is quoted at 12 hours with a 2.5 hour charge time and a 5 volt DC input over USB-C. Twelve hours is a moderate figure and, as with every portable speaker, applies at moderate volume rather than at maximum. USB-C charging is the right connector for a product of this age.
An auxiliary input is included with a cable in the box, which is genuinely useful for older sources and for situations where Bluetooth is unreliable. A single microphone is listed, which suggests speakerphone capability, though the listing does not describe call handling.
Highlights
- Two-way design with a 3 inch woofer and a 1.5 inch tweeter.
- IP67 rating covering full dust protection and temporary immersion.
- Quoted 12 hours of playback with a 2.5 hour charge time.
- USB-C charging at 5 volts DC.
- Auxiliary input alongside Bluetooth, with a cable supplied.
- Colored lighting for party and outdoor use.
- 4.25 by 4.25 by 9.8 inch cylinder weighing 1.59 pounds.
- Ships with an AUX cable, a hanging line, a USB-C cable and a manual.
Things To Consider
The specification block on this listing contradicts itself repeatedly and contains at least one entry that is simply impossible:
- “Total Ethernet Ports: 1”. A portable Bluetooth speaker has no Ethernet port.
- Range is given as 39 feet in one field and 30 feet in another. Either way, both figures are considerably shorter than the 100 foot ranges quoted by competing speakers, so plan to keep the source device relatively close.
- “Speaker Size: 22 Centimeters” describes the enclosure height, not a driver, while a separate audio driver size field reads 5 centimeters.
- “Subwoofer Connectivity Technology: Wireless”. The drivers are inside the unit; there is no separate subwoofer.
- “Control Method: Touch” in one field and “Controller Type: Button” in another.
- “Speaker Type: Subwoofer” and an age range description of “Teen”, neither of which describes the product usefully.
The listing states no output power figure, no frequency response and no distortion specification, so this page makes no claim about how loud it goes or how it sounds. The phrases loud, extra bass and intense bass in the marketing text are not measurements.
Two further points. The 30 to 39 foot Bluetooth range is the practical limitation to plan around: this is a speaker you keep in the same room or the same corner of a garden as your phone, not one you leave at the far end of a yard. And the listing does not state whether two units can be paired for stereo, which is a common feature at this size and would be worth knowing.
Who Should Buy It, and Who Should Not
Buy this speaker if you want an inexpensive outdoor speaker with a genuine IP67 rating, you value the two-way driver arrangement over a single driver design, and an auxiliary input matters to you. At 1.59 pounds it is light enough to carry easily, and the dust and immersion protection is stated properly rather than implied.
Do not buy it if you need long Bluetooth range, if brand support and warranty handling matter to you, or if you want documented output and frequency specifications. For a larger and louder outdoor speaker, the Monster Adventurer Max is the step up in size, and the Ultimate Ears MEGABOOM 4 offers a longer range and a floating body at higher cost. Similar budget options include the BUGANI Bluetooth speaker and the Anker Soundcore Boost. Our portable Bluetooth speakers category covers the field.
