The StormBox Micro 3 is most compelling as a mounting-friendly speaker. A strap and magnetic base let it occupy spaces where a conventional box is awkward, while a long moderate-volume battery rating and USB-C power output add practical flexibility.
Sound quality is competitive enough to consider, but the buying case should start with those conveniences. What Hi-Fi? liked its midrange and bass yet preferred the less expensive JBL Go 5 for overall sound. 1
The Micro 3 uses a single driver with passive radiators, with XBass for quick emphasis and app EQ for more deliberate adjustment. Its compact enclosure makes placement particularly relevant. Attaching it behind clothing or pointing it away from the listener can matter more than a small change to a preset.
What Hi-Fi? heard a clear, personable midrange and useful bass grip, but also found occasional top-end hardness and preferred the JBL Go 5 in direct listening. 1 That makes the Micro 3 a feature-led recommendation. A buyer interested only in music quality should compare the alternatives at the same price before deciding the battery and mounting extras are worth it.
Two Micro 3 speakers can split left and right channels in TWS or play the same audio in Party Mode. Tribit explicitly limits pairing to the same model, so an older Micro 2 should not be assumed to join. That detail matters if the purchase is intended to extend a speaker already owned.
The built-in microphone handles calls and a connected phone’s assistant. There is no AUX input. USB-C serves power roles, including a 5 W output for a phone. It has no documented USB audio input. These choices suit a simple phone-centered kit.
Tribit specifies 24 hours with default EQ at 50% volume, twice the older Micro 2’s advertised runtime noted by What Hi-Fi?. 1 That is a meaningful generational change for long moderate-level use, while the setting and content still determine actual endurance.
The claimed two-hour recharge requires a suitable 5 V, 3 A supply. Below 20% battery, the speaker reduces output slightly for stability. That means the last portion of a charge may not behave exactly like a freshly charged session. A phone top-up also shares the same battery, so preserving a reserve is useful if both devices need to last.
Tribit specifies the strap for poles around 30 mm in diameter. That is useful information for a handlebar or similar attachment, because overstretching it can shorten its life. The magnet is intended for static metal surfaces, and the manufacturer warns against relying on it on moving vehicles.
IP68 and a stated 1.22 m drop test add reassurance for outdoor use. The port cover must remain sealed in wet conditions. The combination of low weight and several placement options is the real advantage, provided the mounting method matches the surface and movement involved.
The PocketGo is lighter at 220 g and adds memory-card playback, useful for a small offline music library. The Micro 3 is the stronger fit for mounting and phone charging. Existing Micro 2 owners should upgrade for those particular improvements or endurance, with awareness that the new model will not form a mixed-generation pair.
Choose the Micro 3 when a strap, magnetic base and long moderate-volume playback solve practical needs. Its charging features are useful additions, and the mounting limits are clearly documented. For a speaker that will simply sit on a desk, compare sound and price before paying for capabilities that may go unused.

Reviewer found clear midrange and useful bass, but occasional hardness and stronger-value sound from JBL Go 5. Micro 2 predecessor had a 12-hour rating versus 24-hour Micro 3 claim.
