I’ve seen a lot of Bluetooth speakers come and go over the years, but every once in a while, a product pops up that makes me stop and take a closer look. Atlantic Technology’s Nexa 1 is one such device. At first glance, it looks like your typical mid-sized wireless speaker, sleek and portable, ready for a day by the pool or a backyard BBQ. But dig a little deeper and you’ll find it has something pretty rare in today’s streaming-dominated audio world — a microSD card slot.
Why A microSD Card Slot Still Matters in 2025
In a time when everything is about Spotify, Apple Music, and streaming your playlists from the cloud, a microSD card slot might sound like a relic from a bygone era. But that’s what makes the Nexa 1 so fascinating. This feature opens a door to offline, standalone playback without needing a phone or Wi-Fi connection at all. You can load your favorite tracks onto a microSD card, pop it in, and let the music flow freely. No buffering, no interruptions from calls or notifications, just pure, dedicated music playback.
I find this especially useful for outdoor environments or remote spots where internet access is patchy or non-existent. Whether it’s a camping trip deep in the woods, a lazy afternoon at the beach, or even just an area in your backyard with spotty reception, having music that doesn’t rely on streaming is a huge bonus. And for those who like to curate specific playlists for different occasions, the microSD slot lets you carry those playlists anywhere without lugging around your phone or worrying about battery life.
Design and Build: A Speaker That’s Ready for Life Outdoors
Atlantic Technology didn’t just slap in a microSD slot and call it a day. The Nexa 1 looks like it was engineered with serious care and a clear vision for portable power. It sports two 2.5-inch aluminum full-range drivers paired with a rear elliptical passive radiator to boost the bass, delivering a surprisingly full sound for its size. When you’re used to the usual tinny sound from many portable Bluetooth speakers, this one stands out.
What impressed me even more is its IPX5 rating, meaning it can handle splashes, rain, and the occasional dunk near the poolside without breaking a sweat. While I wouldn’t recommend taking it for a swim, you can confidently set it by the water’s edge or use it on a rainy day without fear. For outdoor enthusiasts like myself, that level of durability means it can follow me almost anywhere.
The power output is no joke either — 60 watts from a compact frame is a solid performance. For perspective, the popular JBL Charge 5 offers 40 watts, so Nexa 1 punches well above its weight. You get a robust, room-filling sound that can cut through ambient noise at parties or casual gatherings. The aluminum drivers also give it a clean, crisp tone without sounding harsh or artificial.
Connectivity and Controls: Simple Yet Flexible
On the connectivity front, the Nexa 1 covers all the essentials. Aside from Bluetooth 5.3, which ensures a stable and quick wireless connection, it offers a 3.5mm auxiliary input for wired connections — perfect if you want to plug in an older MP3 player or laptop. The microSD slot, of course, is the standout here, allowing you to switch seamlessly between streaming from your phone and playing directly from your card.
The speaker also supports one-touch stereo pairing, so if you happen to have two Nexa 1 speakers, you can easily link them for a more immersive, wider soundstage. That’s a feature often reserved for higher-end speakers, so it’s nice to see it in this price range. Plus, the built-in microphone lets you handle hands-free calls with clarity, which adds to the speaker’s versatility.
Charging is done via USB-C, a welcome modern touch that ensures fast charging and compatibility with a wide range of cables and power banks. Interestingly, the USB-C port can also be used to charge another Nexa 1, which is a clever way to share power and keep your music going longer.
Battery Life: Enough Juice to Last the Party
With about 15 hours of battery life per charge, the Nexa 1 isn’t the longest-lasting speaker on the market, but it’s more than enough for most day-to-night uses. From morning workouts to evening hangouts, I found it keeps pace without the constant worry of running out of power. Considering its power output and sound quality, the balance Atlantic Technology strikes here is commendable.
For users who are always on the move or tend to forget to charge their gadgets, it’s smart to carry a portable charger or pick up an extra Nexa 1 for stereo pairing and shared charging.
Price and Availability: A Competitive Offer for U.S. Buyers
The Nexa 1’s MSRP is \$199, which might sound steep at first glance given the crowded Bluetooth speaker market. However, Atlantic Technology has been running promotions dropping the price to around \$149, making it a very tempting option. I stumbled across some glitches on their website where the product page disappeared briefly, so I’d keep an eye on their official store to snag a deal when it reappears.
If you prefer shopping through U.S.-based retailers, platforms like Amazon, Best Buy, and B\&H Photo Video are good bets for availability and competitive pricing. Amazon frequently offers fast shipping and customer reviews to help make the purchase decision easier. Best Buy’s brick-and-mortar presence also allows you to test out similar models and compare before buying online or in-store. B\&H is another trusted source, especially for audio enthusiasts, often bundling deals or extended warranties.
How Does Nexa 1 Stack Up Against The Competition?
In the \$150 to \$250 price range, you’re swimming in a sea of options from big names like Sonos, JBL, and Marshall. For instance, the Sonos Roam 2 often grabs headlines for its balanced sound and smart home integration, and it’s currently going for about \$143 on sale. That’s close to Nexa 1’s promotional price, but it lacks a microSD slot, so it depends on how much you value offline playback.
JBL’s Charge series offers rugged design and decent sound, but again, no microSD slot and usually lower wattage. Marshall’s portable speakers lean heavily into retro design and branding with sound tuned for rock and roll vibes, but they come at a higher price and with fewer playback options.
What sets the Nexa 1 apart is that rare combination: solid sound quality, water resistance, a microSD slot for offline music, and a price point that undercuts some premium offerings when on promotion. For those who want a versatile speaker that doesn’t force you to rely solely on streaming, it’s a rare find.
Personal Impressions: Music Freedom and Practicality Combined
I’ve had a chance to test the Nexa 1 in different environments — indoors, outside at a picnic, and even poolside. The microSD slot quickly became my favorite feature. There’s something gratifying about loading a card with your top jams and not worrying about phone calls or Bluetooth dropouts interrupting the vibe.
Sound-wise, it’s punchy and clear. Bass is impressive for the size, and the mids and highs come through nicely, making vocals and instruments shine. The aluminum drivers definitely contribute to that refined sound profile. Plus, the speaker’s weight and size make it easy to carry around but still feel substantial enough to sit securely on any surface.
I also appreciate the straightforward controls — no complicated apps or gimmicks needed. Just plug, play, and enjoy. The IPX5 water resistance means I don’t stress if it gets a splash or two, which is liberating when you want music outside without babysitting your gear.
Where to Buy in the U.S.

A Unique Speaker in a Crowded Market
Even though the microSD card slot feels like a throwback, it’s actually a smart differentiator for Atlantic Technology’s Nexa 1. This speaker isn’t just about pumping out sound — it’s about giving listeners freedom to play music their way, wherever they want, without the usual reliance on smartphones or internet connections.
If you crave quality audio with a splash-proof design and the unusual flexibility of offline playback, this speaker deserves a serious look. It’s a reminder that sometimes, mixing old-school features with modern tech creates the best of both worlds.
