Tribit StormBox Micro 2 review

The best cheap speaker on the market, and a better buy now than it was at launch.

The Tribit StormBox Micro 2 is the best cheap Bluetooth speaker we know of: IP67 sealed, twelve hours of battery, a properly tuned passive radiator, and a molded rubber strap that mounts it to a handlebar or a pack with no accessory. A Micro 3 now exists, which is precisely why this one is such good value.

This is the clearest illustration of the tactic that saves the most money in this category. The Micro 2 was an excellent speaker when it launched and it is an identical speaker now — the only thing that changed is that a successor arrived and the price fell. Nothing about the product got worse.

What it does well

The passive radiator is properly tuned. People consistently guess the speaker is larger than it is, which is the whole point of the design — an undriven cone resonating with the main driver genuinely extends usable low end, costs nothing to run, and is the correct engineering answer to a small cabinet. Why cheap speakers sound cheap covers the physics.

The strap is the best in the category. A molded rubber loop that wraps a handlebar, a rucksack strap, a tent pole or a boat rail and tensions against itself. It costs the manufacturer almost nothing and it fundamentally changes where the speaker can go — which is why it beats far more expensive rivals on bike and golf cart duty.

IP67, not IPX7. Certified dust-tight as well as waterproof, at a price where that is genuinely unusual. Several speakers costing three times as much only manage IPX7.

315 g. Light enough that it lives permanently in a bag rather than being packed deliberately, which is the difference between a speaker you own and a speaker you use.

Where it cuts corners

Ten watts is ten watts. Outdoors with any wind it runs out of headroom quickly, and a passive radiator extends bass rather than creating it. This is a close-range speaker and pushing it does not work.

It does not float. Fine beside a pool, wrong in one. The UE Wonderboom 4 is the pick if the speaker will end up in the water.

It is superseded. That is the source of the value and also a real caveat: color choices and stock are thinning, and Tribit discontinues quickly. If you find one at a good price, that window tends to be short.

Support is thin. Tribit's warranty handling and firmware cadence are noticeably behind Anker's and JBL's. At this price that is a rational trade, but it means this is the wrong choice for a speaker you expect to be replaced when it fails.

If you want a carabiner instead of a strap

JBL Clip 5

The carabiner is the whole product, and it is a genuinely good one.

What it does well: A metal carabiner hooks onto fixed points — a shower caddy, a bag loop — more easily than a strap wraps them. Same IP67 rating, same twelve hours, plus Auracast and JBL support.
Where it cuts corners: Considerably more expensive, and less bass than the Micro 2 despite the price.
Who it is for: Showers and bags with fixed hooks.

Battery: 12 hours, plus up to 3 more in Playtime Boost mode
Water rating: IP67 — submersible to 1 m for 30 minutes, dustproof

If you want to spend less still

Soundcore Select 4 Go

The honest answer at the very bottom of the market.

What it does well: IP67 and twenty quoted hours — nearly double the Micro 2 — at an even lower price, from a brand with better support.
Where it cuts corners: Five watts against ten, and bass is effectively absent rather than merely limited. The strap is less substantial.
Who it is for: Showers, tents and single-person listening.

Battery: 20 hours
Water rating: IP67 — submersible to 1 m for 30 minutes, dustproof
Output: 5 W
Weight: 265 g

The Micro 2 itself, summarized

Tribit StormBox Micro 2

The best-argued cheap speaker on the market, and now a last-generation bargain.

What it does well: IP67, twelve hours, a properly tuned passive radiator and the best integrated mounting strap in the category — at last-generation pricing.
Where it cuts corners: Ten watts is thin outdoors, it does not float, support is thin, and stock is thinning as it is phased out.
Who it is for: Cyclists, hikers, travelers and anyone who wants maximum speaker per dollar.

Battery: Up to 12 hours
Water rating: IP67 — submersible to 1 m for 30 minutes, dustproof

Who should skip it

Anyone hosting outdoors. Ten watts will not cover a patio of people.
Anyone buying for a pool. It sinks.
Anyone who wants long-term support. Tribit's is thin, and this model is being phased out.
Anyone prioritizing battery. The Anker Soundcore 2 doubles it for similar money.

Where it appears on this site

The Micro 2 is our best overall pick on best under $50, bike speakers and camping speakers, best value on best under $100 and best for the money, and the value alternative throughout Tribit vs JBL and JBL alternatives.

Frequently asked questions

Is the Tribit StormBox Micro 2 worth buying?

Yes — it is the best cheap speaker we know of, with IP67 sealing, twelve hours of battery and the best integrated mounting strap in the category. Its successor's arrival has made it better value still.

Should I buy the Micro 2 or the Micro 3?

The Micro 2, unless the Micro 3 fixes something you specifically need. The outgoing model is unchanged in quality and cheaper for it, which is the single most effective money-saving tactic in this category.

Does the StormBox Micro 2 float?

No. It is IP67 rated so a dunk is survivable, but it sinks. For in-pool use the UE Wonderboom 4 is the pick.

Is 10 watts enough?

For one or two people at close range, yes — the passive radiator makes it sound larger than the number suggests. Outdoors with wind or a group, no.

Is the strap actually useful?

It is the best feature on the speaker. It wraps handlebars, pack straps, tent poles and rails without an accessory and tensions against itself, which is why it beats more expensive rivals for bikes and camping.
