Tribit Stormbox Micro 3: two-minute review

Four years after its predecessor launched, the Tribit Strombox Micro 3 has landed — and it’s been well worth the wait. This new model offers plenty of improvements over what came before, with a higher power output, extended battery life, faster charging, and a refined look. But is it worth picking over the competition? Here’s what I think after a week of testing.

First of all, we have to talk about sound. This speaker may be small, but it packs 13W of output power, which is nothing to sniff at. Its dynamic full-range driver links up with two passive radiators for impressive volume, and genuinely hard-hitting bass. When listening to low end-focused genres like House and Hip-Hop, I was wowed by the speaker’s bass output — it’s powerful and full-bodied, but never seems muddy or compromising to other sounds in the frequency range.

You also get clear mids and articulate treble, with solid balance using the speaker’s default sound signature. Sure, you’re not going to get the high-fidelity, openness, or detail that some more premium options in our best Bluetooth speakers guide offer, but the Stormbox Mini 3 still sounds admirable given its limited confines and tempting low price.

Something else I love about the Stormbox Micro 3 is its plentiful playtime. You get up to 24 hours here — double of what the Stormbox Micro 2 could deliver. Combine that with faster charging speeds and the capability to charge external devices, and you’ve got a seriously strong performer in the battery life category.

Other changes, like improved waterproofing, a newer Bluetooth version, and a novel magnetic base only help to make the Stormbox Micro 3 feel like a worthy successor to the Tribit Stormbox Micro 2 — a model we absolutely loved.

A lot of returning features, including a built-in mic, multi-speaker pairing, and extensive EQ options also stand Tribit’s small-sized speaker in good stead against the competition. The much-beloved JBL Go 4, say, doesn’t have hands-free calling capabilities, has a more humble output power, and lacks the detailed EQ controls you'll get here.

Still, that’s not to say that the Stormbox Micro 3 is perfect. I touched on its revamped design earlier, which gives it a more rounded look and provides the logo with a cleaner, more striking feel. But this speaker still isn’t the prettiest I’ve seen, and the lack of color options hold it back from greatness in terms of design.

Regardless, its dust and waterproofing, drop-proof build, and compact size ensure that the Stormbox Micro 3 is a highly practical model, and one that’s ideal for taking on the go. And many of my other complaints are mere nitpicks — the lack of backwards compatibility with the Stormbox Micro 2 plus a modicum of compression when listening at higher volumes, but these are extremely common gripes for speakers of this size.

All in all, the Tribit Stormbox Micro 3 is a very capable small-sized speaker. And the fact its price has barely changed from last time out makes it a seriously attractive proposition. At $64.99 / £62.99 (about AU$130), it’s an absolute steal, and considering the quality it posts across the board, I’d say that it’s one of the best value Bluetooth speakers I’ve ever tested. As a result, it’s an easy recommendation for me to make.

Tribit Stormbox Micro 3 review: price and availability

• List price of $64.99 / £62.99 (about AU$130)
• Released in April 2026

The Tribit Stormbox Micro 3 was first released in April 2026, about four years after the Stormbox Micro 2. Thankfully, the new speaker comes in at an extremely similar price to its predecessor — it will only set you back about $64.99 / £62.99 (about AU$130), which is a great price given its talents.

Tribit Stormbox Micro 3 review: features

• Battery life has been doubled to 24 hours
• Lots of customization options with Tribit app
• Multi-speaker pairing, but no backwards compatibility

The Stormbox Micro 3 has had quite the refresh in terms of features. The most striking is its improved battery life — you’re getting up to 24 hours this time out, which is double the amount of playtime you got on the Stormbox Micro 2. Of course, if you’re listening at higher volumes and using the XBass function, you’ll struggle to get that maximum 24 hours, but in my testing I found that number to be pretty accurate.

On top of that, the Micro 3 charges a lot faster than its predecessor. Tribit notes that you can get its lil’ speaker’s battery to 100% from empty in just 2 hours — a big leap from the 2.5-3 hours required to juice up the Stormbox Micro 2.

As we saw last time out, you can also use the Strombox Micro 3 to charge up other devices with a USB-C cable. That’s a pretty handy feature if you need to give your phone or wireless earbuds a boost, for instance, and the higher battery capacity makes this feature feel more worthwhile.

The new Stormbox Micro also has an improved Bluetooth version — it’s using Bluetooth 6.0, which gives you 45m of range, ideal if you want to keep the tunes moving while in a different room.

What’s more, the Stormbox Micro 3 packs 13W of power from its full-range driver (which is accompanied by a couple of passive radiators). That’s better than its predecessor’s 10W, and results in a louder, meatier sound.

Another nice inclusion is the built-in mic, which enables you to take calls hands-free like a speakerphone. I tried this out, and was genuinely surprised by the clarity of my speech. Given that a lot of rivals (JBL Go 4, I'm looking at you) skipped the mic, this was great to see.

You can also customize the sound of this speaker using the Tribit app. There are a nice range of EQ presets, including genre-specific options, and some designed for specific environments, like Outdoor. There’s also a nine-band equalizer, giving users the chance to tailor sound to their specific tastes.

In addition, there’s an XBass mode for those that really want to ramp up the low-end. I steered clear of this, though, as it just made the low-end sound overpowering, and caused the speaker’s battery to drain at a faster rate.

Finally, you can pair the Stormbox Micro 3 with a second, identical unit to activate stereo sound. Typically, audio will be downmixed to mono, so this is a useful feature — I just wish Tribit had let us pair with the Stormbox Micro 2 as well, something that would’ve given owners of that model a better reason to upgrade.

Tribit Stormbox Micro 3 review: sound quality

• Powerful, well balanced sound
• Seriously commendable bass from such a small speaker
• Lacks the mid and treble range finesse that premium rivals supply

Given its limited confines and low price, the Tribit Stormbox Micro 3 doesn’t sound perfect — you’ll experience some compression at higher volumes, and there are no fancy codecs like LDAC or aptX Adaptive. But still, the speaker performed pretty admirably in my testing.

I’ll start by saying that I spent most of the time using Tribit’s Signature EQ — XBass is here for a bumped-up low end, and there are a few other presets, but the standard tuning had a more balanced, controlled sound, so I rarely felt tempted to deviate from it.

For me, the most impressive thing about the Stormbox Micro 3 is its bass output. So many small-sized speakers fall flat here — even some more premium models sound as if there’s nothing going on whatsoever in the low-end, resulting in a thin, de-energized presentation.

But not the Stormbox Micro 3. In tracks like Harmony in the Distance by M-High, I was struck by the pumping, impactful bass that never sounded lethargic or bloated. Indeed, the low-end hit pretty hard considering this model’s small form-factor, but at the same time, it never drowned out synths in the mids or higher frequency percussion.

In this track, treble also sounded surprisingly sharp, with a rapid decay to ensure drums hit with rhythmic precision. They didn’t have the full-sounding fidelity you’d expect to hear on more premium speakers, though — something I’ll get onto shortly.

Moving over to one of my favorite tracks, Space Cowboy by Jamiroquai, and the Stormbox Micro 3 maintained impressive quality. Vocals were nicely weighted in the mix, and funky bass occupied a well-defined pocket, never seeming over-eager or muddy. At one point, the vocals and bass cut, as the tune built towards its euphoric climax, and the speaker recreated the re-entry of various instruments with finesse, indicating its solid dynamics.

With really deep, demanding records, such as Morning Wonders - Leo Pol Remix by Kolter, Tribit’s tiny speaker still managed to hold its own. The dark, rippling bass was perhaps a little too much for it to handle, but it still put up a valiant effort, while translating the aggressive higher-pitched percussion with control, rather than letting it fly off the handle.

So far, the Stormbox Micro 3 was doing pretty nicely, but I wanted to turn up the temperature, so I decided to test it against a pricier rival from a big name: the Bose SoundLink Micro Gen 2. Now, for all of my gripes with Bose’s small-sized speaker, I have to say it sounds pretty good, with vibrant treble, expressive mids, and clean bass. So how did Tribit’s mini rival compare?

I started with a tech house track, Good Luck from ADR (UK) and OUTTEN, and straight away, I realized how the Tribit replicated low-end sounds with much more confidence and vigor than its Bose counterpart. Despite lacking some low-end punch, the SoundLink Micro Gen 2 produced cleaner overall audio in my view, with more refined clarity in the treble range in particular.

It was similar in Shinchiro Yokota’s Do It Again, with Tribit conjuring up more regimented, full-sounding bass, but less polished highs. The Bose really did struggle with some of the darker sounds, though, and despite its impressive clarity further up the frequency range, you’d expect more given its hefty asking price.

It’s with softer tracks, though, like Yellow Giant Reprise by Tatsuhiko Asano, where the Stormbox Micro 3’s limitations are laid bare. Mids just sounded more detailed, open, and separated on its Bose rival, and although Tribit’s speaker still plated up perfectly clear and non-distorted sound, it failed to offer that premium edge.

Overall, though, this comparison showed me the fantastic sound for pound value of the Tribit Stormbox Micro 3. Sure, it lacked the nuance and grace of the SoundLink 2 in the mid-range and treble, but it still performed solidly in those areas, while also producing far more energized bass and higher volume potential than its Bose rival.

It’s also worth noting that I mainly kept the Stormbox Micro 3 upright, typically while magnetized to my fireplace. It sounded great with this configuration, but you can also lay it flat, which has a less rounded, but still enjoyable sound.

• Sound quality score: 4/5

Tribit Stormbox Micro 3 review: design

• New rounded design still not the prettiest
• Magnetic base with handy silicone strap
• IP68-rated and drop-proof

The Tribit Stormbox Micro 3 looks pretty similar to its predecessor, but it's got a slightly more rounded build and a neater, more striking logo at its center. It’s not the prettiest small speaker I’ve seen — the retro-style Marshall Willen II and modern Bose SoundLink Micro 2 have a more premium, eye-catching aesthetic, although they’re also quite a bit pricer.

What I do like, however, is the practicality of the Stormbox Micro 3. First of all, this new model comes with a magnetic base, which makes it easy to fix to a shower or fridge. I had the speaker attached to the fireplace by my desk, which worked fantastically.

There’s also a strap on the reverse side of the model (carried over from previous iterations), which makes it easy to hook onto a bag, bike, or hook, so this is a very versatile speaker placement-wise. And it’s incredibly compact, which means you could easily chuck it in a bag when it’s out of use as well.

What’s more, the Tribit Stormbox Micro 3 has an IP68 rating, meaning its fully dustproof, and can survive a 1.5m dunking underwater for as long as 30 minutes. That’s an improvement over the previous model’s IP67 rating, and while it’s fairly unessential, it’s pleasing to see Tribit keep up with the likes of JBL’s water-resistant tech.

The Stormbox Micro 3 is also drop-proof, making it ideal for taking on the go. Tribit says that it can survive being dropped from about 1.2m, in-line with US military standards — so you shouldn't have to worry about it taking the occasional tumble.

Other than its average looks, my only complaint would be the Stormbox Micro 3’s lack of color options. You can only grab it in Black at the moment, while its predecessor could be purchased in Blue, Red, or Mint instead. Hopefully more colorways will be released down the line, but that lack of vibrancy is a shame, particularly given the vivid options supplied by Bose and JBL, among others.

• Design score: 4/5

Tribit Stormbox Micro 3 review: value

• Plenty of improvements over predecessor with next to no price bump
• Strong sound at this price-point, with great bass output
• High battery life and durable build make it a slam dunk

When it comes to value-for-money, I’m not entirely sure you can do better than the Tribit Stormbox Micro 3. We already raved about its predecessor's high quality paired with a low price, and things are much the same here.

There’s been next to no increase in list price against the Stormbox Micro 2, in spite of macroeconomic pressures, and you get even more for your money this time. More power, better battery life, a magnetic design, a more rounded look…this is a worthy improvement over a speaker we already loved.

For just over $60 / £60, you’re going to make a few sacrifices. You don’t get the stellar detail, nuance, and open sound that some small-sized rivals can offer — but they’ll come at a significantly steeper price-point. The Stormbox Micro 3 still sounds very good overall too — even if it can be outclassed, the clarity and balance on offer is highly commendable.

And given that the Stormbox Micro 3 performs very nicely in the low-end — an area where a lot of small speakers struggle, you’re getting plenty of bang for your buck as far as sound goes.

I was also delighted by the Stormbox Micro 3’s exceptional battery life, which is higher than a lot of premium rivals. Combine that with a durable build, and almost everything you could want from a small speaker can be yours at a very modest price indeed.

How I tested the Tribit Stormbox Micro 3

• Spent one week testing
• Mainly streamed tunes over Tidal
• Reviewed by someone who’s tested more than 40 Bluetooth speakers

I spent one week testing the Tribit Stormbox Micro 3, predominantly using it at home — both stood upright and resting on its base.

When listening to music, I made sure to stream tunes over Tidal, starting with the TechRadar testing playlist, which features tracks from a wide variety of genres. I also bumped a range of tunes from my personal library, and tried out the speaker’s different sound modes and mic functionality.

More generally, I’ve spent in excess of two years testing audio gear here at TechRadar, which includes everything from the best wired earbuds through to premium wireless headphones. I’ve tried more than 40 Bluetooth speakers during my time here, and personally curated our guide to the best Bluetooth speakers, so I know exactly what is required for a model to stand out in this heavily convoluted market.
