Bose SoundLink Plus First Look: is this the premium portable to beat?

It's mid-afternoon in the garden, the barbecue is finally behaving, and the little speaker you bought a few summers ago has just flashed its low-battery warning for the third time. You want something that lasts until the last guest goes home, survives a knock into the paddling pool and sounds like more than a tinny phone. Bose's SoundLink Plus is pitched precisely at that moment, but at around £250 it needs to earn its place in your basket.

At a glance: the confirmed numbers

Bose SoundLink Plus: What Exactly Is It? Positioning, Launch Details and UK Pricing

First, a bit of clarity, because Bose's naming can make this look like a sequel. It isn't. The SoundLink Plus was an entirely new model when it arrived in 2025, not a follow-up to some earlier SoundLink Plus, and Bose doesn't label it "1st Gen". It launched alongside the SoundLink Micro (2nd Gen), according to Bose's UK press release.

Bose announced it in the UK on 12 June 2025, and it went on sale on 26 June 2025 at an RRP of £249.95. That was well over a year ago, so this is now a settled, widely reviewed product rather than a fresh unknown. RTINGS, SoundGuys, WIRED, What Hi-Fi?, Expert Reviews and TechRadar have all published verdicts, and RTINGS refreshed its review as recently as August 2026.

There's one size and one hardware configuration. The Amazon UK listing covered here is the Black colourway; at launch Bose also offered Blue Dusk and a limited-edition Citrus Yellow, then added a limited-edition Sunset Peach, which was available in the UK by April 2026. Colour is the only difference: same drivers, same battery, same features.

On price, think of £249.95 as the ceiling rather than what you must pay. Bose's own UK store's pricing varies by colourway: the Citrus Yellow page has listed it at £199.95, while other colour pages have shown the full £249.95. Promotions at Amazon and Argos have previously brought it down to around £199 too. Across the Atlantic, Bose itself cut the US price from $269 to $179, a sign of how promotional this corner of the market is. Check the current figure for your chosen colour before you commit.

Inside the Enclosure: Drivers, Materials and Why Bose Won't Talk Wattage

Pop the grille off in your imagination and you'd find a fairly busy little box. Bose uses one subwoofer/mid-bass driver, one tweeter and four passive radiators. That last number is the interesting one: four radiators is an unusually generous allocation for something this size, and it goes a long way towards explaining the weighty, bass-forward character reviewers keep describing.

Passive radiators are unpowered diaphragms that move in sympathy with the air pressure inside the box, helping a small enclosure produce low-end it otherwise couldn't. More of them generally means more bass reach without a bigger cabinet, which is exactly the trick Bose is pulling here.

What Bose won't tell you is just as revealing. There's no driver diameter, no amplifier wattage and no frequency-response range in its specifications. TechRadar specifically called out the missing frequency-response and amplifier-power figures in its review.

Toughness Audit: IP67, Floatation and Whether It Can Actually Live Outdoors

This is where the Plus starts to make a case for its price. It carries an IP67 rating, meaning it's sealed against dust and rated to survive immersion. In Bose's terms, that's up to roughly 1m of water for up to 30 minutes. And if it goes over the side of a paddleboard or into the lake, it floats.

What Hi-Fi? dunked its review sample in a sink and reported no ill effects, which is reassuring for anyone who's watched a cheaper speaker give up after one wet afternoon. Reviewers broadly agreed the Plus feels like a credible outdoor product: the steel grille, grippy silicone and fixed carry loop all point to something built for gardens, campsites and beaches rather than a mantelpiece.

For context, SoundGuys' comparison lists the JBL Charge 6 with an IP68 rating, which is technically a step above IP67. In practice, both are well beyond splash-proof. The Plus's floating design is the more practical party trick if you're near open water.

The 20-Hour Promise: What Bose Claims vs What Independent Labs Measured

Battery claims on portable speakers are often optimistic. Bose's "up to 20 hours" claim for the SoundLink Plus holds up unusually well, and this is the single strongest argument for buying one.

Bose's figure is based on fairly specific conditions, so it's worth knowing what they are before comparing:

Now the independent results. SoundGuys ran the speaker at a steady 80dB SPL and recorded 20 hours 55 minutes, comfortably beating the claim. RTINGS logged 19.1 hours on its own test, which it described as almost 20 hours. Two different labs, two different methods, both landing within a whisker of Bose's number.

Runtime figures from SoundGuys, RTINGS and Bose documentation. Bars scaled to a 22-hour maximum.

Translate that into real life and you're looking at a long weekend camping at sensible volume, or a full day of garden listening with plenty left over. SoundGuys considered that endurance a highlight, and it's better supported by independent data than many speaker battery claims.

The slow lane: charging

Here's the flip side. Bose quotes up to five hours to charge from empty using a 15W (5V/3A) USB-C supply, and there's no mains adaptor in the box, just a USB-C-to-USB-C cable. RTINGS measured about 4.6 hours; Expert Reviews put it at roughly five and called that unusually slow. WIRED and RTINGS also flagged it, and Android Central reported just over five hours.

There's no fast-charge mode, but you can play music whilst it charges. The practical habit is simple: plug it in overnight before a trip, and use a proper 15W charger rather than an old low-power phone brick, which will stretch that wait even further.

Does It Actually Sound Like a £249 Speaker? Reviewer Consensus Decoded

Sound is where opinions diverge a little, though less than you might expect. The broad consensus: full, punchy and entertaining, with more scale than its size suggests, but not the tightest or most refined presentation at its price.

SoundGuys provides the most objective view through its MDAQS scoring system, which models how listeners would rate a speaker's sound. The Plus scored 3.3/5 overall, which SoundGuys described as good but not exceptional for a speaker of this size.

SoundGuys MDAQS scores for the Bose SoundLink Plus.

Read those scores together and a clear picture forms. Timbre, essentially how natural instruments and voices sound, is the strong suit. Immersiveness is weaker, which makes sense for a single mono box. The distortion score suggests it doesn't stay perfectly clean as it's pushed, which chimes with RTINGS' observation of compression at maximum volume blunting punch and clarity.

The subjective reviews flesh that out. WIRED praised weighty, room-filling sound with robust bass and more power than the size suggests, and particularly liked the clarity on vocals, acoustic guitar and woodwinds. What Hi-Fi? called it rich, full-bodied, bold, punchy and entertaining. Expert Reviews found it substantially punchy, with useful timbral detail and enough dynamic headroom when a recording builds.

Where they push back is bass control. What Hi-Fi? found rivals' bass tighter and snappier, and Expert Reviews said the low frequencies can feel detached from the rest of the presentation. RTINGS described a broadly balanced response with boosted high bass but limited deep-bass extension. In other words, lots of thump, less of the deepest rumble, and not always perfectly in step with the rest of the music.

Bose's Walled Garden: App, Codecs, Multipoint and the Features That Are Missing

Connectivity is modern where it counts, if a little sparse around the edges. What Hi-Fi? summed up the feature set as comparatively bare-bones, and that's fair, but the essentials are well covered.

Setup and controls follow the Bose pattern: connect through the app, tweak the sound if you want, and leave it be. If you already use Bose headphones or a Bose soundbar, it'll slot in with very little fuss, and SimpleSync gives it a role indoors as well as out.

The missing pieces are worth thinking about before you buy, because none of them can be added later.

£249.95 Buys What Exactly? Weighing Up the Premium Portable Market

To judge whether the Plus is worth its RRP, it helps to see how reviewers framed it against the speakers people most often cross-shop. A clear note first: the JBL Charge 6, JBL Xtreme 4 and Bang & Olufsen Beosound A1 3rd Gen appear here only as context drawn from reviewer coverage. They aren't picks in this article.

SoundGuys ran a head-to-head against the JBL Charge 6 with an identical battery test. The Bose lasted 20 hours 55 minutes at 80dB; the Charge 6 managed 13 hours 15 minutes under the same conditions. That's a clear Bose win on endurance, more than seven extra hours.

Despite losing on battery, the JBL still scored higher overall with SoundGuys, 8.4 against 7.6. SoundGuys rated the Bose's value at just 6.0/10, arguing cheaper rivals deliver comparable performance, and recommended waiting for a sale. It credited the Bose with longer endurance, floatation and aptX Adaptive, while judging the JBL the better value overall.

The JBL Xtreme 4 is the other name that came up repeatedly. What Hi-Fi? reviewed it at around £249, so it's priced alongside the Bose's RRP. It's a larger speaker that plays louder, and What Hi-Fi? found it more nuanced and cohesive, with tighter, snappier bass. The Bose answers back with a smaller, more portable body, aptX Adaptive and the ability to float.

TechRadar compared the Plus with the Bang & Olufsen Beosound A1 3rd Gen and ultimately preferred the B&O, citing its 24-hour rated battery, built-in microphones for calls and more refined, immersive sound. Still, TechRadar considered the Bose a strong choice, particularly when discounted, and noted its more rugged, rough-and-ready design and typically lower UK price on sale.

Who Should Actually Put This in Their Basket

Strip it back and the SoundLink Plus is a specialist rather than an all-rounder. It does a few things very well and skips several things entirely. That makes the buying decision refreshingly clear.

A gentle word of caution for the "I'll just buy two for stereo later" plan. Two Plus speakers would cost you roughly double the outlay, so if stereo is important to you from day one, weigh that against a single larger stereo speaker such as Bose's own SoundLink Max, which RTINGS considered better for music.
