If you want a speaker that reads like a prop from a space‑sci‑fi set and delivers big, cinematic sound to match its looks, the Mars Pro is one of the most compelling mid‑range choices you can buy in the UK for roughly £199.

Design: a Miniature Mech that Owns the Room

The Mars Pro looks intentionally like a piece of movie hardware — a compact orb of machined metal perched on three articulated tripod legs, with an aesthetic that riffs on retro‑futurism, mecha and rugged sci‑fi props. The main shell is made from zinc alloy, giving the unit a cool metallic sheen and a satisfying, weighty feel that separates it from ordinary plastic speakers. The sculpted panels, visible fasteners and layered surface textures read as mechanical detail rather than mere ornamentation, so the speaker feels like a small probe or a battle‑scarred drone you’d expect to find in a film set.

The three legs aren’t just decorative: they’re articulated and poseable, changing the speaker’s stance and silhouette so you can present it as a surveying sentinel or a squat, stable display piece. That tripod silhouette — equal parts robotic tripod and studio prop — makes the Mars Pro a natural focal point for streaming backgrounds, gaming desks and curated shelf displays.

RGB Lighting, Controls and Tactile Showmanship

At the heart of the Mars Pro is an RGB core and multiple light zones that can pulse, cycle or sync with music to create a tiny light‑show. Gravastar builds in several dynamic lighting modes (six common modes across models) that let the speaker glow as ambient decor or react to beats for an immersive visual/audio moment. The lighting transforms the piece from gadget to stage prop, especially in low light.

Top‑mounted controls are touch sensitive: a volume slider with LED feedback and convenient tactile buttons for power, Bluetooth pairing, playback and lighting modes keep the silhouette clean while feeling futuristic to use.

Materials, Heft and Presence

This is not a pocketable novelty. The zinc alloy shell and robust legs make the Mars Pro a display‑first object; at about 2.5 kg (roughly 5.5 lb) it sits on desks and shelves like a small sculpture rather than a travel speaker. The metal construction delivers a premium heft and gives the Mars Pro a durable, collectible feel.

Sound: Cinematic, Immersive, and Characterful

Gravastar tunes the Mars Pro for presence. Expect punchy lows, sparkling highs and an overall voicing that favours immersion and excitement rather than studio neutrality — ideal for space‑sci‑fi playlists, cinematic scores and gaming sound design where atmosphere matters. For listeners who prioritise strictly neutral, analytical reproduction, dedicated reference monitors will be preferable; for most fans who want memorable sound to match bold visuals, the Mars Pro shines.

Colourways, Limited Runs and Collectible Finishes

The Mars Pro is offered in standard finishes (Black and similar core colours) plus a rotating set of special and limited editions. Hand‑finished models such as the War‑Damaged Yellow and numbered Captain editions bring weathered paint, scuffs and individualized patinas that sell to collectors. Gravastar has also produced themed tie‑ins (for example a branded Assassin’s Creed edition) and more stylised runs like Aurochs and Shark‑14 — each variant leans into storytelling through paint and texture.

Pricing: Simple, Straightforward

The common UK retail price for the standard Gravastar Mars Pro is about £199. Limited or hand‑painted editions typically carry a premium and commonly fall into higher price bands (individual special editions and limited runs often retail in the £200–£280 range depending on rarity and finish). If you want a special or numbered edition, expect to pay more — and move quickly, because limited runs often sell out.

Where to Buy and Practical Tips

For genuine stock and clearer warranty terms, buy from Gravastar’s official store or an authorised UK retailer; the Mars Pro is carried by major UK outlets which helps with returns and local support. If you want a particular limited finish, follow Gravastar’s channels and be ready to order when new runs drop — hand‑painted and themed models often disappear fast. When pairing, the Mars Pro supports TWS/stereo linking in supported configurations, so buying a second unit can widen the soundstage for cinematic listening.

Who Should Buy This — and Why it’s Perfect for Space‑Sci‑Fi Fans

If you curate a space‑sci‑fi aesthetic — think synth-wave dens, streaming cockpits, model displays or gaming theatres — the Mars Pro gives you a tactile, characterful object that instantly reads as part of the fiction. It’s ideal for streamers who want on‑camera charisma, gamers who want immersive, bass‑heavy sound and collectors who prize limited, hand‑finished hardware pieces. If you demand clinical monitoring for critical listening or prioritise ultra‑broad aftercare networks above look and character, mainstream hi‑fi brands will still cater better to that niche.

A Quick Note on Longevity and Support

The Mars Pro’s metal build and collectible finishes give it a durable, cherished feel, but as with many design‑forward products, availability, edition pricing and regional service can vary. Buying through official or authorised UK channels will give you the best path to warranty handling if you need it.

Final Thought — a Prop that Plays Music

Gravastar’s Mars Pro is more than a speaker: it’s a small, weighted piece of sci‑fi stagecraft that happens to make satisfying, cinematic sound. For fans of space‑sci‑fi aesthetics who want their tech to communicate a story as well as fill a room with music, the Mars Pro is a rare object that marries design theatricality with credible audio performance — and for the UK buyer, it’s available around £199 for the standard model, with collectible variants at higher prices for those who want a one‑of‑a‑kind finish.
