Overview
The NOTABRICK Vi Portable Bluetooth Speaker arrived in late 2025 as a compact, cylindrical unit targeting the party-and-lifestyle crowd. NOTABRICK isn't a household name yet, but the Vi makes a solid first impression — the metallic build feels sturdier than you'd expect at this price, and unboxing it reveals a tighter fit and finish than many competing speakers in the same bracket. At roughly 8 inches tall and under 1.5 pounds, it slides into a backpack without any hassle. The RGB light show is clearly front and center as a selling point, pulsing visibly even in daylight and genuinely adding to the speaker's personality rather than feeling tacked on.
Features & Benefits
The Vi runs on dual full-range drivers with a combined claimed output of 30W — though it's worth noting the spec sheet lists 15W per channel, so take the headline figure as marketing shorthand rather than a strict audio measurement. Real-world volume is still respectable for the size, handling outdoor spaces without struggling. The IPX7 waterproof rating is genuinely useful, meaning rain, splashes, or shower steam aren't a concern. Battery life is a standout: the 3600mAh cell is rated for just over 16 hours of continuous play, and USB-C charging brings it back up in under four hours. Bluetooth 5.0 holds a stable connection up to 100 feet, and the TWS stereo pairing option — linking two units for 60W combined — is a nice upgrade path for larger spaces.
Best For
This waterproof Bluetooth speaker is an easy pick for anyone who needs reliable outdoor audio without babysitting the weather forecast. Beach trips, pool days, and backyard barbecues are natural fits — the waterproofing holds up to full submersion, not just surface splashes. It also works well as a shower or kitchen speaker that happens to look good doing it, thanks to the beat-synced lighting. Buyers considering a second unit should know TWS pairing works across both Bluetooth and AUX modes, which is more flexible than most competitors offer. If you're chasing precise soundstage, this isn't your speaker. But for casual listeners who want volume plus ambiance at a fair price, the Vi genuinely delivers where it counts.
User Feedback
With over 300 verified ratings at a 4.6 average, this portable RGB speaker has built a credible track record for a brand that only launched this model in mid-2025. Most buyers lead with praise for battery endurance — many report it lasting well beyond a single day of casual use without reaching for the charger. The lighting draws consistent compliments for looking more premium than the price suggests. On the critical side, a handful of reviewers note that bass thins out at higher volumes, which is honest feedback for a speaker of this physical size. A few mention early pairing quirks in TWS mode, though those appear isolated. Build durability after extended outdoor use draws mostly positive notes, with no widespread reports of hardware failures.
Pros
- IPX7 waterproofing holds up to full submersion, making it genuinely pool and beach safe.

- USB-C fast charging brings the unit back to full in under four hours, which is convenient.
- The beat-synced RGB lighting looks more premium than the price suggests and adds real ambiance at night.
- Bluetooth 5.0 maintains a stable connection at distances up to 100 feet without frequent dropouts.
- TWS stereo pairing supports two units over both Bluetooth and AUX modes, offering flexible expansion.
- At under 1.5 pounds, the NOTABRICK Vi is light enough to toss in a bag without a second thought.

Cons
- Bass quality softens and loses definition at higher volume levels, which is a real limitation.
- The 30W output claim conflicts with the 15W-per-channel spec — the marketing figure is misleading.
- NOTABRICK has a limited long-term track record, making durability over multiple years harder to assess.
- Some buyers report early pairing instability in TWS mode, particularly during initial setup.
- A single unit may struggle to fill larger outdoor spaces without distortion creeping in.
- No companion app means you cannot adjust EQ settings or customize lighting behavior beyond onboard controls.
- The cylindrical tabletop form factor limits placement options — it does not hang or mount easily.
- Color availability is limited to Metallic Black, which may not suit all buyers.

Suitable for:
The NOTABRICK Vi Portable Bluetooth Speaker is a strong match for casual outdoor enthusiasts who want reliable, waterproof audio without spending a lot. If your typical use case involves beach days, poolside hangouts, backyard gatherings, or even just a lively shower playlist, the IPX7 rating and respectable battery life make this a practical daily companion. It suits people who appreciate visual personality in their gear — the beat-synced RGB lighting genuinely adds atmosphere at evening gatherings and costs nothing extra. Buyers who might eventually want to expand their setup will appreciate that TWS pairing with a second unit is supported over both Bluetooth and AUX, which is more flexible than most options in this price range. It also works well as a kitchen or desk speaker for someone upgrading from a cheap, tinny unit and wanting noticeably better volume and clarity without a major investment.
Not suitable for:
The NOTABRICK Vi Portable Bluetooth Speaker is not the right call for listeners who prioritize audio fidelity above everything else. At this size and price point, deep, controlled bass is simply not in the cards — high volumes can thin out the low end noticeably, which will frustrate anyone who takes bass-heavy genres seriously. The brand is still relatively new and lacks the long-term reliability track record of established names, which matters if you need confidence in warranty support years down the road. The advertised 30W output figure requires scrutiny, as the spec sheet reflects 15W per channel — buyers expecting concert-level loudness from a single unit may find real-world performance more modest than the marketing implies. If you need a speaker for a large indoor space, a conference setting, or serious listening sessions, this waterproof Bluetooth speaker punches below what those scenarios demand.
