The Tribit Stormbox Micro 2 is a compact, rugged Bluetooth speaker designed for portability and outdoor use. With an IP67 rating against water and dust ingress, and a built-in strap for easy attachment to bags, panniers, and bikes, it's well-suited for on-the-go listening. It also features Bluetooth 5.3 for multi-device pairing, can be paired with a second speaker for stereo sound, and includes a USB-C port that doubles as a power bank to charge your phone.
Our Verdict
The Tribit Stormbox Micro 2 is a tiny speaker, so it can't deliver an immersive music listening experience. It has a forward-facing design and downmixes your audio to mono, so don't expect a lush stereo soundstage. Its small size also means it can't put out much low-end, but it has enough high-bass to keep basslines audible, and its mid-range and treble are well-balanced, so voices and instruments sound accurate. Its companion app also comes with a flexible 9-band EQ, so you can tailor its sound to your liking. In general, although this speaker scores poorly, it does a good job given its constraints.

The Tribit Stormbox Micro 2 isn't well-suited for watching videos or movies. It's a very small speaker, so it can't reproduce deep rumbles from explosion effects. It downmixes stereo audio to mono, so your audio doesn't feel very immersive. It also doesn't get very loud, and at max volume, it compresses your audio. Finally, this speaker has fairly high Bluetooth latency on both Android and iOS, which can cause noticeable lip-sync issues. However, some apps and devices may help offset this with built-in latency compensation. All that said, this small speaker won't be your first choice for watching movies, but if you're at a park and desperate to show your friends a funny YouTube video, it'll do the trick.

The Tribit Stormbox Micro 2 is satisfactory for listening to podcasts. The mid-range is well-balanced, so voices do come through clearly, though they may sound a touch honky depending on pitch of the speaker. The built-in strap makes it easy to attach the speaker to a bag or handle, and it's very small, making it easy to carry around with you. But since it uses front-facing drivers, you'll usually want to ensure the speaker is facing you.

The Tribit Stormbox Micro 2 portable speaker doesn’t have a built-in voice assistant, so you'll need to rely on the assistant from your connected smartphone, without support for hands-free activation. On the upside, it does an excellent job picking out your voice from background noise when you're nearby, but it has difficulty recognizing voice commands from a distance.

The Tribit Stormbox Micro 2 is decent for its intended purpose of use outdoors. It has an excellent build quality, and its IP67 rating means it'll withstand both heavy rain and dusty conditions alike. Its battery lasts about eight hours at our calibrated testing volume of 80 dB. After that, it drops about 5 dB. In all, the battery will get you through a day at the park, but it's probably not enough for a weekend camping trip. Still, you can use the speaker to charge devices like phones, which is a nice touch. Since it's so small, it's highly portable, and its built-in silicone carrying strap makes it easy to attach the speaker to bags or bikes. It'll fit in larger coat pockets, too. Of course, its small size means it also can't get very loud or reproduce much bass, but its balanced mid-range means most audio still sounds accurate, if a touch thin. It also downmixes audio to mono by default, though you can pair it with a second unit to enjoy stereo playback.

Differences Between Sizes And Variants
The Tribit Stormbox Micro 2 comes in three color variants: 'Black,' 'Blue,' and 'Red.' We tested the 'Red' variant, and you can view its label.
If you encounter any other variants of this speaker, let us know in the comments, and we'll update the review accordingly.
Compared To Other Speakers
The market for small, portable, outdoors-focused Bluetooth speakers is very competitive. If size is your top priority, the best alternative to the Tribit Stormbox Micro 2 is probably the Anker Soundcore Select 4 Go. It has a larger volume than the Tribit but is a bit lighter in weight. Neither of these tiny speakers can reproduce much bass, but the Anker's design means the sound varies a bit less with your listening angle. Of the two, only the Tribit has a built-in microphone for use with your device's voice assistant. If battery life is important to you, the Sony SRS-XB100 is well worth considering. For a similar price to the Tribit, it offers a 360-degree design that lets you enjoy the same sound from any angle (although it still downmixes your audio to mono) and has a fantastic 20-hour battery life while still being small enough to fit into the palm of your hand. Finally, if you're looking for a highly portable speaker that offers great sound (for its size), the Ultimate Ears WONDERBOOM 4 is a great choice. It's a bit bigger than the Tribit and usually a little more expensive, but its mid- and treble-ranges are virtually flat, and it plays back stereo audio beautifully from its 360-degree design. However, the Ultimate Ears doesn't support voice assistants.

The JBL Clip 5 and the Tribit Stormbox Micro 2 are the same weight, although the Tribit's smaller volume makes it a bit easier to fit into a coat pocket. Still, both these speakers are tiny, highly portable, and come with IP67 ratings to protect them from rain and dust. Neither speaker puts out any low-bass, which is to be expected given their size, but the JBL's inflated high-bass means your audio sounds a bit warmer than the Tribit's. Still, some people might find that warmth a little boomy, but both speakers offer EQs in their companion apps, so you can tailor their sound to your liking. On balance, the Tribit is the better speaker because it has a built-in microphone, and you can charge your phone with it.
The Tribit Stormbox Micro 2 and the Anker Soundcore Select 4 Go are comparable speakers with different strengths. They're both tiny enough to fit in coat pockets and have built-in carrying hooks, making them easy to take on a hike. Since they're both so small, don't expect these to do justice to your favorite techno tracks, but they'll pack a bit more punch than your phone's built-in speaker. Of the two, only the Tribit has a built-in microphone for use with your device's voice assistant, and you can also use it as a battery pack to charge your phone. That said, the Anker is cheaper.
The Sony SRS-XB100 is a better portable speaker than the Tribit Stormbox Micro 2, with a couple of caveats. The Sony's 20-hour battery life is twice as long as the Tribit's, and it has a 360-degree design, so your audio sounds the same from any angle. The Sony also puts out a fair bit more bass than the Tribit. On the other hand, the Tribit's companion app has an EQ, so you can tailor the sound to our preferences, and you can also use it like a battery pack to charge your phone.
The Ultimate Ears WONDERBOOM 4 is a better speaker than the Tribit Stormbox Micro 2, although that's to be expected since it's a bit bigger and more expensive. The Ultimate Ears offers razor-flat mids and treble and plays back your audio from its 360-degree design without downmixing it to mono. That said, the Ultimate Ears doesn't support voice assistants, and you can't use it like a battery pack to charge your phone, unlike the Tribit.
Test Results
The Tribit Stormbox Micro 2 has a compact, square shape with a low-profile design. It comes in three colours: 'Blue,' 'Black,' and 'Red.' We tested the 'Red' variant. The front face has the Tribit logo along with three buttons. Its small size makes it easy to slip into a backpack or a larger coat pocket. A built-in silicone strap on the back allows you to attach the speaker to a hook or bag, and it can also help the speaker stand upright on a flat surface.
The Tribit Micro 2 is remarkably portable. It fits in the palm of one hand and will slip into larger jacket pockets with ease. It also has a small silicone strap that can attach to a bag for added convenience.
The Tribit Micro 2 has an excellent build quality. It's covered in a durable-feeling silicone and is solid and well-built enough for outdoor use, especially since its IP67 rating means it will withstand both a downpour of rain and a dusty, windy day. It also floats in water, but not well enough to keep your audio sounding clear. The back of the speaker is covered in a rubberized plastic and has four raised feet for added grip and durability. On the front, the speaker drivers are covered by a tightly woven mesh that feels tough and protective.
There's a silicone strap on the back, which you can use to attach the speaker to bike handles or to position the speaker vertically. The strap unhooks on one side via a small nub and feels unlikely to break. If there's an obvious weak point, it's the lack of a cover on the USB-C charging port. That said, the speaker's IP67 rating means that it shouldn't be an issue, but it's worth noting.
The Tribit Micro 2 has very good controls. There are three physical controls on the front of the unit, all of which produce a satisfying click, making them easy to access and use. Unsurprisingly, the plus and minus buttons control the volume while the circular central button serves several purposes. You press it once to play or pause audio, twice to skip forward, and thrice to skip backward. Pressing and holding it will activate voice assistant mode. Finally, a short press accepts a call, and a long press rejects a call. You can see the rest of the controls in the manual.
The power and Bluetooth buttons are located on the side of the unit. You press and hold the Bluetooth button to enter pairing mode, and once paired, the Bluetooth LED turns solid blue. You can also use the Bluetooth button to pair the speaker with other Stormbox Micro 2 units for stereo playback or Party mode.
The speaker offers clear audio and visual feedback, including chimes for power, pairing, and max volume. The power button changes color based on battery level. However, there's no chime for minimum volume, and the volume LEDs only light up when the volume is being adjusted; they don't actually show the current level.
The Tribit Micro 2 has middling frequency response accuracy. Since it's a very small device, it doesn't produce much bass at all, so don't expect this to get a techno party started. That said, there's enough high-bass to keep basslines audible. The mid-range is well-balanced, so instruments and voices sound accurate and true-to-life. The treble is also reasonably well-controlled. It's ever so slightly recessed, but since this speaker produces little bass, that helps to ensure your audio doesn't sound too bright. You can also adjust the sound to taste via a 9-band graphic EQ in the companion app. We measured the effect of various EQ presets on the sound of this speaker when in an upright position.
We tested this speaker in an upright position because that produced a more balanced frequency response than it did lying on its back. That said, as you can see in the Soundstage box, the speaker has better directivity when on its back. It's also worth noting that although there is a peak on the frequency response graph at 58.2Hz, this isn't audible with regular content.
The Tribit Stormbox Micro 2 has a middling soundstage. It downmixes stereo audio to mono, but that's unsurprising given its small size. Still, since it has a forward-facing design, its directivity isn't very good, so your audio sounds different depending on your listening angle. That said, the directivity is better if you place the speaker on its back, with the drivers pointing upward.
The Tribit Stormbox Micro 2 has a disappointing dynamics performance. Its max volume isn't very loud, but that's to be expected from a speaker of this size. For comparison, it reaches similar volume levels to the JBL Go 4. It also compresses your audio a fair amount at max volume, reducing the overall bass output. That said, this small speaker doesn't put out much bass in the first place.
It's worth noting that if this speaker is positioned on its back, it offers a slightly better dynamics performance.
This speaker has a decent battery life. The brand advertises that you'll get 12 hours of play time, but we've listed the battery life as just over eight hours. After that, the playback volume dropped by about 5 dB in our tests. This drop happened regardless of the playback volume. In order to ensure a fair comparison between different speakers, the time we've listed is how long the speaker played back audio at 80 dB, which is our calibrated testing level. That said, battery life varies depending on your use and playback volume.
The speaker turns off after about 15 minutes of inactivity or five minutes without connecting to another device. You can change the power-saving settings in the app. The speaker also has a white LED light that displays the battery level during use and charging.
It's worth noting that you can also use this speaker as a battery pack, meaning you can charge devices like phones via its USB-C port.
The speaker doesn't have built-in voice assistant features. You'll need to use the assistant on your paired smartphone, but this means voice activation isn't supported. On the plus side, it does an excellent job separating your voice from any ambient noise around you, provided you're close to the speaker. It struggles to understand voices from far away.
This speaker comes with a disappointing app. It lets you change between six EQ presets (Music, Audiobook, Rock, Party, Classical, Jazz) and also make your own using the 9-band graphic EQ. You can store up to 20 of these personalized presets, which is a nice touch. Still, beyond that, the app doesn't offer many extra features. You can upgrade the firmware, perform a factory reset, change the voice prompts, and set the auto-shutdown battery-saving feature. The app doesn't let you link this speaker to other units for either stereo playback or Party mode, but you can do so using the Bluetooth button on the unit.
The Tribit Stormbox Micro 2 can't play audio via a wired connection. You can use its USB-C port to charge the speaker or, in a nice twist, charge another device. If you're out and about and your phone lacks a little juice, just connect it to the speaker, and it'll charge.
The Bluetooth connectivity is good. The speaker uses Bluetooth 5.3, and you can pair up to two devices at once with it. That said, you have to pause the audio on one device before hitting play on the other. The latency with both iOS and Android is high enough to cause slight lip-sync issues when watching content, although different apps and devices compensate for latency in different ways.
