The speaker at the top of this list weighs 6.5 kilograms. The one in seventh weighs 700 grams. Both are sold as "portable", and the ranking has an opinion about which is better that you should probably overrule.
Power output and bass extension are what this category scores on, and both scale with box size. So read the score as loudness and depth, then apply the question the score cannot ask: will you actually carry it? Every figure below is the live computed Mars Score.
Highest score in the catalog: JBL Boombox 3
Mars Score 87.5 at $499. 180 W and bass down to 40 Hz — the deepest in the category by 5 Hz and nearly a third more power than anything else here — with IP67, 24 hours of battery and a power-bank output.
It also weighs 6.5 kg, two and a half times the next-heaviest speaker on this list. This is a thing you put in a car, not in a bag.
The one most people should buy: JBL Charge 6
Mars Score 81.9 at $199. 45 W, 55 Hz, IP68 — the only fully submersible speaker here — 28 hours of battery, a power bank out, and 1,010 g. It scores second on a sixth of the leader's weight and 40% of its price.
Who should buy it: anyone who wants one speaker for the beach, the shower and the kitchen.
Most power per dollar: Anker Boom 2 Plus
Mars Score 81.8 at $199 — the same price as the Charge 6 with 140 W and 45 Hz, three times the power and much deeper bass, at 2.7 kg. If the speaker lives on a patio rather than in a rucksack, this is the better $199.
Best big-speaker compromise: JBL Xtreme 4
Mars Score 80.9 at $379. 100 W, 53 Hz, 2.15 kg, 24 hours, power bank out. It is the point on the curve where a speaker is still carryable with a strap and still fills a garden.
Best sound quality for the size: Bose SoundLink Max
Mars Score 80.7 at $399. 120 W and 45 Hz from 2.36 kg — the best bass-to-weight ratio in this top ten, and the reason Bose charges what it does.
Lightest serious speaker: Marshall Emberton III
Mars Score 79.3 at $179. 700 g and 32 hours of battery — the longest runtime here — with IP67. Its 20 W output is the lowest in this top ten by a wide margin and its 60 Hz floor is the shallowest, which is exactly what a speaker this small should be honest about.
Who should buy it: people who want music in a room, not a party in a field.
Best-looking: Bang & Olufsen Beosound Explore and Beosound A1 (3rd Gen)
79.4 at $199 and 78.3 at $349 respectively, both 60 W, both around 600–630 g, both IP67. The Explore is the outdoor-shaped one with 27 hours; the A1 reaches 5 Hz deeper and costs $150 more for materials rather than for sound. Neither has a power-bank output.
The one with a missing number: Logitech MEGABOOM 4
Mars Score 78.0 at $249. 60 Hz, IP67, 20 hours, 1.23 kg — and Ultimate Ears does not publish a wattage figure, so we record it as absent rather than guessing. That gap is why this speaker's score is computed from fewer inputs than its neighbours, and it is a deliberate choice: an invented number would rank it confidently and wrongly.
Best sound at home: Sonos Move 2
Mars Score 76.7 at $449. 70 W, 47 Hz, 3 kg, and IP56 — the weakest water rating in this top ten by a distance (splash-resistant, not washable). It is last here because it is not really competing in this category: it is a Sonos home speaker with a battery, and its argument is multi-room and Wi-Fi streaming, neither of which this category scores.
How to choose, in four questions
- Weight: 600 g to 6,500 g. Be honest about the trip you actually take. The top of this list is not portable in any normal sense.
- IP56 to IP68. Only the Charge 6 survives being dropped in a pool. IP67 handles rain and a sink; IP56 handles a splash.
- Power-bank output is on four of these ten and is the feature people find most useful after the fact.
- Bass floor, 40 Hz to 60 Hz, is the difference you hear immediately — and it is the specification that forces the size.
