ULTIMEA M20 Pro or Apollo S40 Pro: which budget soundbar wins?

Display / screen quality

There’s no display or screen here, so this category is really about how clearly each soundbar helps you hear what’s on screen. On that front, the Apollo S40 Pro has the edge because it includes VoiceMX for clearer dialogue, plus HDMI support for a more reliable TV connection. If you watch a lot of BBC dramas, ITV soaps, Channel 4 box sets, or late-night films where dialogue gets buried, that extra clarity matters more than raw wattage. Winner: Product B.

Performance

The Poseidon M20 Pro is the louder-looking spec sheet on paper: 132W peak power versus 100W on the Apollo S40 Pro, plus a built-in subwoofer in a compact 16-inch body. That suggests stronger all-in-one output and potentially more punch for small to medium rooms. However, the Apollo S40 Pro counters with a 2.2ch design, BassMX tuning, and a detachable layout that can improve stereo separation and placement flexibility. For sheer headline power, Product A wins; for balanced everyday TV sound and clearer voices, Product B is likely the better performer overall. Winner: slight edge to Product B for real-world listening, but Product A wins on raw power.

Build quality and design

The M20 Pro is the simpler product: a compact 16-inch all-in-one soundbar with a built-in subwoofer, which makes it neat, space-saving, and easy to position under smaller TVs or on a desk. The Apollo S40 Pro is more versatile thanks to its 2-in-1 detachable design, which is useful if your setup is awkward or you want more placement options. For a tidy one-box solution, Product A is more straightforward; for flexibility and a more premium-feeling feature set, Product B takes it. Winner: Product B.

Battery life

Neither product is battery-powered, so this is not a relevant differentiator. Both are mains-powered soundbars designed to stay under the TV, not portable speakers. Winner: tie.

Price and value for money

This is where the decision gets much easier. Product A costs £49.99, while Product B costs £75.99, a difference of £26.00. Both have the same 4.4/5 rating from 2,770 reviews, which is important: you are not paying more for a clearly better user score. If your goal is simply to improve TV audio on a budget, the Poseidon M20 Pro delivers the better value because it gives you strong specs for a much lower outlay. Winner: Product A.

Game library / features

There’s no game library here, but there are gaming-relevant features. The M20 Pro is billed as an all-in-one PC soundbar for game use, and its Bluetooth 5.4 plus app control make it attractive for a monitor or small desk setup. The Apollo S40 Pro is more TV-focused, with HDMI, Optical, Aux, BassMX, and VoiceMX, which makes it better for console or living-room use where lip-sync and dialogue matter. If you want a desk-friendly bar for PC and casual gaming, Product A is appealing; if you want broader TV connectivity and better voice clarity for games and streaming, Product B wins. Winner: Product B.

Overall user experience

Both products are from the same brand, share the same rating, and sit in the same budget-friendly ULTIMEA family, so you’re not choosing between good and bad, but between simple value and extra refinement. The Poseidon M20 Pro is the easier recommendation for anyone who wants the cheapest route to much better TV audio, especially in a smaller room or as a basic all-in-one setup. The Apollo S40 Pro feels more complete: HDMI support, detachable design, BassMX, and VoiceMX all point to a more polished experience for people who care about dialogue and flexibility. Overall winner: Product A for value, Product B for features.

Overall summary: if you want the best buy on pure value, the Poseidon M20 Pro is the stronger choice because it is £26 cheaper, has higher peak power, and matches the Apollo S40 Pro’s rating. If you want the more capable and better-rounded soundbar, the Apollo S40 Pro wins on connectivity, dialogue clarity, and design flexibility. For most UK buyers on a budget, Product A is the smarter purchase; for those who want the nicer all-round package, Product B is the premium pick.
