After the excellent debut with LEGO® 10302 Optimus Prime, and the later release of LEGO® 10338 Bumblebee, LEGO® 10358 Soundwave becomes the first official Decepticon to land in the LEGO® Icons line.
An absolute icon of the G1 generation, Soundwave arrives in a LEGO® version filled with details, surprising features, and a sincere tribute to the original 1980s character.
With 1,505 pieces and a retail price of €189.99, this set is designed both as a display piece and as a building challenge, cleverly mixing Technic and System elements in a truly original way.
In this review, we will take a closer look at LEGO® 10358 Transformers Soundwave: from the building experience to the G1-inspired transformation, including the play features, the included minions, and a direct comparison with the original 1980s toy.
What’s inside the box?
At the heart of the set, of course, is Soundwave, fully transformable into the classic cassette player, just like in the G1 series. But the appeal doesn’t stop there.
Alongside him, you’ll find:
Laserbeak and Ravage, both cleverly recreated and able to transform into real microcassettes,
and a miniature version of Soundwave, designed to enrich the display with a direct nod to the character’s mass shifting ability, accompanied by two printed tiles depicting the minions in cassette form, reproduced at a smaller scale.
A display plaque is also included, adding elegance and a true collector’s touch.
Among the extras, a sound brick stands out, seamlessly integrated into Soundwave’s chest, reproducing sounds inspired by the analog aesthetic of the 1980s.
Finally, two small but meaningful details: the option to switch the eyes (red for the animated version, yellow for the original toy), and an instruction manual full of insights, with 12 numbered bags to guide you step by step through the build.
Building Experience
The LEGO® 10358 Soundwave offers a construction journey divided into distinct phases, each featuring mechanical, aesthetic, and functional solutions designed to impress not only LEGO® fans but also enthusiasts of robotics and 1980s pop culture. Let’s break them down:
Building the minions: Laserbeak, Ravage, and Mini-Soundwave
The opening stage focuses on three accessories that immediately showcase the level of care put into this design.
Laserbeak: built with a clever shaping of the wings using slopes and wedge plates, and with an extraordinary attention to symmetry and balance. The printed tiles and clips perfectly emulate cassette details, while the side weapons cleverly repurpose flat silver minifigure heads, creating a striking visual effect.
Ravage: more articulated than Laserbeak, featuring segmented legs, a flexible tail, and a body built with vertical layering. In cassette mode, every detail locks perfectly into place thanks to a clever design that ensures both compactness and precision.
Mini-Soundwave: a micro tribute to the main character, designed for display and built with printed tiles that echo the classic G1 packaging. It’s not just a decorative piece: with its display base, it adds a narrative touch, becoming a small easter egg that symbolically interacts with the main model.
Soundwave
The construction of the LEGO® 10358 Soundwave body alternates between System bricks and Technic reinforcements, with a modular design that makes the assembly smooth yet never trivial. The squared structure, a hallmark of the G1 character, lends itself perfectly to the LEGO® building language, resulting in a compact, solid robot with an unmistakable silhouette.
The chest and the sound brick
Soundwave’s chest is one of the most rewarding moments of the build: an interplay of plates, tiles, and slopes forms the iconic transparent window with the printed Decepticon logo. The hatch opens through a clever lever mechanism, allowing the minion cassettes to be inserted inside.
The LEGO® sound brick (code 6488969) is flawlessly integrated and completely hidden from the outside. The “Play” button is not just a decorative detail: pressing it activates the brick, which plays Soundwave’s digitized catchphrases, making him not only faithful to the original but also more interactive than ever before.
Head and interchangeable eyes
The head is compact and detailed, with sharp lines and a printed visor. A unique feature is the option to swap the interchangeable eyes, choosing between the yellow visor of the original toy version and the red one from the animated series. A neat touch that allows collectors to personalize the look based on their own memories.
Arms and shoulders
The shoulders are built with a reinforced ball-and-socket joint, allowing for wide rotations and stable bends. The forearms house the cannons and feature refined details using printed tiles and inverted slopes. The articulated hands provide a good range of poses, with each finger mounted on an independent clip—an elegant solution, though slightly fragile.
Legs and transformation
The legs are solid and robust, built with overlapping layers and an internal Technic joint that ensures stability in robot mode and perfect alignment when converting to the tape recorder. The transformation is the heart of the set: it happens without removing any parts, thanks to the smart use of brackets and hidden pins.
In robot mode, Soundwave looks imposing, faithful, and with the right stage presence.
In tape recorder mode, the front is clean and convincing, with compact and symmetrical proportions; the back, however, is noticeably less “clean” and inevitably shows joints and folded arms.
The transformation: simple, clean, elegant
One of the biggest challenges in LEGO® Transformers is maintaining the dual form without sacrificing aesthetic consistency. Here, Soundwave truly shines:
The transformation requires no disassembly.
The movements are guided, fluid, almost “choreographed,” in perfect continuity with the Hasbro G1 model.
The final result in “tape recorder” mode is compact and symmetrical.
It’s an old-school transformation, but refined with modern techniques.
The sound brick
One of the most surprising and unexpected features of the LEGO® 10358 Transformers Soundwave set is the inclusion of a fully functional sound brick (LEGO® code 6488969), seamlessly integrated into the model’s chest. It’s not just a “gimmick,” but a narrative choice that turns the build into a multisensory object.
The brick has been programmed to reproduce a series of Soundwave’s iconic catchphrases, with digitized audio that recalls the electronic distortions typical of the character’s voice in the G1 series. Among the included lines are:
“Danger, Autobots detected!”
“Strikeforce assembled”
“Decepticons are awesome”
“Soundwave superior”
From a construction perspective, the integration of the module was designed with great care: a system of plates and wedges transfers the pressure from the button to the sound brick, maintaining alignment without interfering with either the transformation or the model’s stability.
The result is twofold: on the one hand, it amplifies nostalgia, evoking the 1980s atmosphere of the original Transformers; on the other, it adds a unique experiential dimension, turning Soundwave into a set that you don’t just look at or transform, but one that actually… talks.
Comparison with the original G1 Soundwave
The LEGO® 10358 Transformers Soundwave is not just a construction set—it’s a love letter to one of the coldest and most fascinating icons of the Transformers universe. To fully understand its significance, it’s essential to place it side by side with its historical counterpart: the G1 Soundwave, distributed by Hasbro in 1984 and based on the original Takara “Micro Change MC-10 Cassette Man” mold.
To be precise, the one shown in the photos next to the LEGO® version is not the 1984 release, but the Hasbro/Takara reissue from 2024 celebrating the 40th anniversary of Transformers. A faithful replica, and the perfect reference for our comparison.
From the very first glance, the LEGO® 10358 Transformers Soundwave conveys the same visual identity as the G1. It’s a job well done, where every key element finds a consistent translation into the language of LEGO® bricks. Even the weapons are reproduced with surprising accuracy, to the point of seeming traced directly from the original model.
The original G1 toy had a clear purpose: to be playable, transformable, and recognizable in both forms. It achieved this, but with the limitations of its time: simple joints, limited articulation, and fragile plastics. LEGO® embraces that legacy, reinterpreting it through a modern lens, but always in a consistent and respectful way. It’s a set that will satisfy even the most demanding collectors.
Some inevitable differences remain. On the G1 (in cassette mode), there was a volume wheel on the left side and a button on the right: details that, in the LEGO® version, were omitted because they would have overlapped with the folded legs at the back. A reasonable choice.
The arms, too, were different: the G1 had retractable hands operated by a small lever, sliding them in and out to make the robot more compact in tape recorder mode. In the LEGO® set, the hands are fixed and articulated, but also somewhat fragile. It might have been interesting to incorporate at least part of that mechanism, even at the cost of sacrificing the gripping effect—which isn’t really necessary anyway, since the weapon is simply “slotted in” rather than firmly held.
Despite these differences, the overall fidelity is impressive: it feels as though you are holding a “brick-built” yet deeply respectful version of the classic Soundwave. Even his “minions,” Laserbeak and Ravage, were recreated with great care: a few color variations (such as in Laserbeak’s wings) don’t compromise a result that successfully captures the G1 spirit in LEGO® form.
In the end, the greatest value of this set is not just technical, but emotional. If the G1 toy had the task of convincingly representing a character, the LEGO® Soundwave has the mission of reactivating emotional memory: that of those who, as children, pressed the Eject button and watched Laserbeak fly off on a mission.
And that’s exactly where the set hits the mark. Because when you finish the build and place Soundwave on your desk, you don’t just see a robot or a tape recorder: you see a fragment of yourself. You see that afternoon in 1986 when your mother said: “Alright, choose a Transformer.”
And you chose Soundwave.
✅ Strengths
Faithful G1 design: a satisfying tribute to the original look.
Smooth transformation: intuitive yet never trivial, with well-thought-out steps that don’t compromise either robot or tape recorder mode.
Integrated sound brick: a brilliant feature that adds interactivity and a unique narrative touch.
Laserbeak and Ravage: true companions, fully transformable and perfectly compatible with the chest compartment.
Refined building experience: alternates System and Technic pieces with advanced and rewarding solutions.
Exclusive elements: printed tiles, interchangeable eyes, display base—details that elevate the perceived value.
18+ target & nostalgia factor: designed for collectors and longtime fans, it’s more of a display piece than a playset.
❌ Weaknesses
Fragile hands and fingers: tend to come off easily.
Limited articulation: especially in the legs, reducing poseability compared to a modern action figure.
Messy back in cassette mode.
Price: may seem high when judged solely by piece count, though the Hasbro license adds significant value.
Conclusion
If you are a Transformers fan, or have a personal connection to the G1 generation, this is a purchase worth every cent. It’s a set that combines clever engineering, nostalgia, and display presence like very few others, truly capturing the spirit of the original Soundwave with the elegance of LEGO® bricks.
For those simply looking for a build-and-rebuild set, or who judge the price exclusively by the “pieces per euro” ratio, it might not be the ideal choice. But for true fans… it’s a direct hit to the heart.
The LEGO® 10358 Transformers Soundwave is much more than just a display set: it’s a bridge between past and present. It faithfully reinterprets the legendary 1984 G1 model, bringing back its transformation, details, and charisma—but with the strength and ingenuity of LEGO® design.
Minor flaws, such as fragile fingers or reduced poseability, fade into the background when faced with a set that celebrates the legacy of Transformers and turns it into a unique building experience.
There’s no doubt: this Soundwave is destined to become one of the bestsellers of autumn and Christmas 2025, uniting two generations of fans under the same symbol—between nostalgia and innovation.
