The SoundLink Plus positions itself as the more refined, heavyweight option in the Bose lineup. Built with a powder-coated steel grille, rubberized controls, and an IP67 rating that makes it dustproof, waterproof, and even float-capable, it blends durability with style. This is the model for people who want deep bass and clear mids in a speaker that handles poolside and living-room use equally well.
On the other hand, the SoundLink Flex (2nd Gen) leans into portability. Compact, lightweight, and designed with a built-in loop for easy carrying, it suits music lovers who want to take their sound anywhere. Despite its smaller footprint, the Flex still sounds bold and layered. It works on hikes, beach days, or quick backyard parties without weighing down your bag.
The SoundLink Plus brings a longer 20-hour battery life and even doubles as a 15W USB-C power bank, making it a practical choice for extended trips or heavy listening sessions. The SoundLink Flex 2nd Gen, with its 12-hour battery life, counters with extreme portability and rugged durability that can withstand water, dust, rust, and sand. Each model shares Bose’s advanced features like multipoint Bluetooth connectivity, stereo pairing, and EQ customization through the Bose app, but the experience of using them day-to-day feels distinct.
In simple terms, the SoundLink Plus is for anyone who wants fuller sound and doesn’t mind a larger body, while the SoundLink Flex (2nd Gen) is for those who prize convenience, portability, and outdoor toughness. Below we cover design, performance, features, and pricing so you can pick the right one.
Product Overview
The SoundLink Plus is Bose’s newest portable powerhouse, designed to deliver bigger sound, longer battery life, and extra functionality, including a power bank. Meanwhile, the SoundLink Flex (2nd Gen) takes everything people loved about the original Flex and refines it into a more travel-friendly, rugged, and affordable package. Both models share Bose’s balance of clarity and bass, but their designs, features, and ideal use cases differ.
Bose SoundLink Plus – What You Need to Know
Debuting on June 26, 2025, the Bose SoundLink Plus is the latest midrange portable speaker from Bose, positioned between the compact SoundLink Flex (2nd Gen) and the beefier SoundLink Max. Priced around $269 in the U.S., with options in Black, Blue Dusk, and a limited-edition Citrus Yellow, the Plus aims to hit that sweet spot of powerful performance and everyday usability.
It uses a single mid/bass driver, a tweeter, and four passive radiators crammed inside a rugged, backpack-ready body. With an IP67 rating, it’s built to withstand dust, full submersion in water, and even floats, so it works at the beach or indoors. It runs on Bluetooth 5.4, supports SBC, AAC, and aptX Adaptive codecs, and even lets you charge your phone via its 15W USB‑C charge-out port.
If you’re all about long listening sessions, the 20-hour battery life (with roughly a 5-hour charge time) gives it the longer battery of the two. Plus, it offers multipoint Bluetooth so you can switch between two devices, and connects via the Bose app for EQ tweaks and software updates.
The SoundLink Plus suits music lovers who want refined, full sound in a rugged portable package. If you prioritize bold bass, crisp clarity, extended battery life, and a built-in power bank, this is your pick. It is heavier than its smaller sibling, so weigh that if you often carry it on long hikes or travels.
Bose SoundLink Flex (2nd Gen) – What You Need to Know
First arrived in September 2024, the SoundLink Flex (2nd Gen) isn’t a full overhaul but a smart evolution of its 2021 predecessor. At around $149, it retains the same candy-bar silhouette, durable silicone-rubber body, IP67 protection, and lifestyle loop, but now includes some upgrades.
Bluetooth 5.3 replaces the older 4.2, adding Snapdragon Sound for higher-fidelity streaming via aptX (when paired with compatible phones), plus a redesigned control strip and shortcut button to improve usability. The battery life remains around 12 hours, and while that’s fine for casual listening, it’s not a leap over the original.
The Flex 2 is convenient. It’s super lightweight (about 589g), still floats on water, and holds up like a champ through beaches, hikes, and poolside drop-ins. The sound is balanced, with decent bass and clarity, and already solid, though you may need some EQ adjustment in the Bose app for the best results.
This model caters to the adventure-seeking audiophile or vibe-conscious listener who wants Bose-level sound in a speaker that snaps right onto your pack or hangs from a hammock loop. If you need high ruggedness, automatic orientation tuning (PositionIQ), and small-form portability without compromising too much on audio quality, the Flex (2nd Gen) checks all those boxes, especially now that it’s often discounted, even dipping below $100 in summer deals.
Design and Build Quality
Both the SoundLink Plus and SoundLink Flex (2nd Gen) combine premium aesthetics and rugged durability, and both go from a polished living room to a dusty trail.
Bose SoundLink Plus
The SoundLink Plus has a premium vibe that doesn’t sacrifice toughness. You’ve got a powder-coated steel grille, soft-touch silicone controls, and a reinforced housing that’s both shock- and rust-resistant. Bose says it’s built to handle tumbles. Its IP67 rating means it’s fully dustproof, waterproof, and yes, it floats, so you can take it poolside or drop it in the sand without worry.
The Plus is no featherweight. It measures about 231 × 86 × 104 mm and weighs roughly 1.53 kg (3.29 lb), so it feels substantial in hand. Despite its heft, it looks sleek thanks to its matte-finish and clean silhouette. You get Black, Blue Dusk, and a limited-edition Citrus Yellow, all slick and slightly playful.
Bose SoundLink Flex (2nd Gen)
Now, the SoundLink Flex (2nd Gen) is the minimalist, grab-and-go option. Silicone rubber covers its body, making it durable, edge-friendly, and able to withstand shocks, rust, or random drops. With a solid IP67 rating, it’s dust- and waterproof, floatable, and made for your next adventure.
Smaller and lighter than its Plus sibling, the Flex clocks in at 203 × 45 × 89 mm and weighs about 589 g (1.3 lb), which is easier to pack. It has a handy nylon utility loop, making it easy to clip onto your backpack or hang right where you play.
While colors can vary depending on the market, limited-edition shades like Petal Pink or Twilight Blue show up in special deals, adding a dash of style for trend-sensitive buyers.
Sound Performance
Design and features might draw you in, but sound performance decides whether a speaker becomes your daily driver. Bose has built its reputation on delivering audio that feels bigger than the box it comes from, and both the SoundLink Plus and SoundLink Flex (2nd Gen) live up to that legacy in very different ways. The Plus aims to be a mini powerhouse, with a driver setup and acoustic design that prioritizes a full sound, layered detail, and a bass response that feels substantial without drowning out the mids. The Flex 2nd Gen, on the other hand, is more about precision and adaptability, balancing frequencies across the board while leaning on Bose’s DSP and PositionIQ technology to optimize playback no matter how or where you place it.
Sound quality depends on clarity, but also on how a speaker performs at different volumes, indoors versus outdoors, and across genres. These two models shape sound differently. The SoundLink Plus emphasizes power and depth, sounding bigger in medium to large spaces, while the Flex 2nd Gen focuses on versatility and balance, making it the better pick for travelers and casual listeners who want consistent audio in any setting.
Here is how each model handles driver setup, sound signature, loudness, and clarity, and how they respond to indoor versus outdoor environments, along with Bose’s digital processing, DSP and PositionIQ.
Bose SoundLink Plus
Under the hood, the SoundLink Plus uses a simple but powerful setup: a single mid/bass driver paired with a tweeter, boosted by four passive radiators that pump up its low-end presence. This combo delivers a sound that feels open, detailed, and bold, with vocals coming through clean and highs that shimmer without sounding harsh.
When you crank the volume, it’s shockingly loud for its size, though reviewers note that extreme volumes can make bass feel a bit dull and lose rhythmic punch. In standard listening zones, its clarity shines, especially on acoustic tracks where every string and breath feels true. Indoors, the sound feels spacious without overkill. Outdoors, the bass still hits, but with lighter walls to bounce off, the radiators do their job mixing depth with reach.
On the tech front, it supports aptX Adaptive for fuss-free Android hi-fi streaming, plus multipoint Bluetooth so you can bounce between your phone and laptop effortlessly. Bose’s basic 3-band EQ helps tweak tonal balance, though it’s not as flexible as more advanced EQs out there.
Bose SoundLink Flex (2nd Gen)
Despite the smaller body, the Flex (2nd Gen) delivers a more balanced, safe sound out of the box, with all frequencies (bass, mids, highs) present but not screaming for attention.
You won’t win any loudness wars with it, but dialing in the EQ (boosting bass by +6 and treble by +3) brings the energy back in, giving kick drums punch and synth layers clarity. Indoors, it’s more midrange‑focused than full-sounding; outdoors, it’s still vivid enough to drive a small hangout playlist. At volumes past ~80%, Bose’s DSP chips in to soften bass, so no rattling your car’s windows accidentally.
It also rolls with PositionIQ tech that auto-styles your sound based on placement (flip it, lean it, or hang it), though it’s subtle and you can’t turn it off.
At a Glance
| Feature | SoundLink Plus | SoundLink Flex (2nd Gen) |
|---|---|---|
| Acoustic Setup | Driver + tweeter + 4 radiators | Balanced driver(s), compact design |
| Sound Signature | Bold, spacious, slightly bass-heavy at volume | Clean, balanced, needs EQ for flavor |
| Volume Behavior | Very loud, some bass slowdown at peak | Moderate volume, DSP tames bass over 80% |
| Orientation Tech | Subtle auto-adjust via PositionIQ |
Features & Smart Technology
Both the SoundLink Plus and SoundLink Flex (2nd Gen) go beyond basic Bluetooth playback, with features like customizable shortcuts, app-based controls, multi-device connectivity, and pairing modes that let you tailor your listening experience. Each model has its own mix, including quick voice access, library-level linking, and two-speaker syncing.
Bluetooth Version & Connectivity
The SoundLink Plus ships with Bluetooth 5.4, the newest spec in the Bose portable lineup, offering faster, more stable connections and improved energy efficiency. It supports SBC, AAC, and aptX Adaptive, giving Android users high-resolution wireless audio with low latency. That makes it a strong choice for both music streaming and casual video playback. The SoundLink Flex (2nd Gen), meanwhile, upgrades from the first Flex’s Bluetooth 4.2 to Bluetooth 5.3. It doesn’t quite have the Plus’s codec arsenal, but it still benefits from stronger stability, longer range, and more reliable multipoint performance than its predecessor. Both speakers handle multipoint pairing, so you can keep two devices connected at once and switch from your laptop to your phone without reconnecting.
Voice Assistant Integration
Neither model has built-in Alexa or Google Assistant, but they do support voice assistant access through your smartphone. Hold the multifunction button and you can trigger Siri, Google Assistant, or Alexa, depending on which phone you’re paired to. It’s a useful feature for hands-free controls when your device is out of reach, though it still depends on your phone’s ecosystem rather than being fully standalone.
App Support
Both speakers work with the Bose Music app, which acts as the control hub. From here you can adjust playback, tweak the three-band EQ, rename your speaker, and manage software updates. For users who want finer control, the app is where the tuning happens. Nudging up bass and treble on the Flex 2nd Gen gives it a livelier sound profile, while balancing mids on the Plus refines its fuller sound. The app also makes pairing multiple speakers a painless process.
Stereo Pairing & Multi-Speaker Setup
You can connect two identical models in stereo mode for true left/right separation, or use Party Mode to sync multiple Bose speakers together for a bigger soundstage. Imagine lining up a pair of Flex 2nd Gens at a beach party or dropping two Plus units in a living room for a DIY surround vibe. It scales your sound without extra hardware.
Unique Bose Enhancements
The SoundLink Flex (2nd Gen) comes equipped with PositionIQ, Bose’s placement detection technology. Lay it flat, stand it upright, or hang it by its loop, and the DSP automatically adjusts to maintain balanced audio output. While it’s subtle, it ensures consistent sound in varied environments. The SoundLink Plus doesn’t use PositionIQ but instead relies on its more advanced acoustic hardware and codec support for higher fidelity playback, giving listeners more raw performance without needing adaptive processing.
Battery Life & Charging
Battery life separates the two clearly. The SoundLink Plus is the endurance champion, offering up to 20 hours of playback on a single charge. Real-world testing shows it can stretch close to 21 hours at moderate listening levels, which means you can get through a full weekend trip without worrying about recharging. It takes about five hours to fully recharge over USB-C, which is on the slower side, but Bose adds a perk: the Plus doubles as a 15W USB-C power bank, letting you charge your phone or another device in a pinch. It’s not as fast as a dedicated charger, but when you’re out camping or at a festival, that little extra versatility can be a lifesaver.
The SoundLink Flex (2nd Gen) suits shorter, lighter sessions. Bose rates it for 12 hours of playback, but in testing at consistent 80 dB levels, it managed closer to seven hours before powering down. That’s a noticeable gap between marketing and reality, but for casual listening at moderate volume, the 12-hour estimate still holds up. Charging runs over USB-C as well, and it gets back to full battery in about four hours, quicker than the Plus, which makes it easier to top up before you head out for the day.
When comparing the two in real-life use cases, the contrast is straightforward. The SoundLink Plus is best suited for long, uninterrupted play sessions: backyard parties, day-long road trips, or extended gatherings where stopping to recharge isn’t practical. Its longer battery life and backup charging feature make it the reliable workhorse. The SoundLink Flex (2nd Gen), however, is the lighter, more agile option. While its runtime is shorter, the smaller size makes it ideal for hiking, beach days, or travel, and its faster charging cycle means it’s easier to keep powered up between outings.
| Feature | Bose SoundLink Plus | Bose SoundLink Flex (2nd Gen) |
|---|---|---|
| Rated Battery Life | Up to 20 hours | Up to 12 hours |
| Real-World Performance | ~20–21 hours at moderate volume | ~7–12 hours depending on usage |
| Charging Port | USB-C | USB-C |
| Full Charge Time | ~5 hours | ~4 hours |
| Extra Functionality | 15W USB-C charge-out (power bank feature) | None |
| Best Use Cases | Long sessions, parties, travel weekends | Short trips, hikes, casual day use |
Portability & Everyday Use
How each speaker fits into your daily life matters as much as how it sounds. For a hike, a beach bag, or a kitchen counter, the difference in weight, form factor, and carrying options will heavily influence which model feels more practical. Bose designed both speakers with durability in mind, but the way they handle portability makes them appeal to different types of listeners.
The SoundLink Plus leans toward the larger, more substantial side. At just over 3 pounds (1.53 kg), it feels hefty in the hand, and while still compact compared to a full-size home speaker, you’ll notice the weight if you’re carrying it for long stretches. Its rectangular design makes it easy to place on flat surfaces, giving it stability whether indoors or outdoors. For everyday use, it works well as a home speaker that can also tag along for road trips or backyard parties. You get the benefit of powerful sound and long battery life, but it’s not the type of speaker you’d casually clip to your backpack for a day hike.
By contrast, the SoundLink Flex (2nd Gen) targets true grab-and-go convenience. Weighing around 1.3 pounds (589 g), it’s light enough to toss in a bag without a second thought. Its slimmer profile makes it easier to carry, and the built-in utility loop adds extra flexibility: you can hang it on a backpack strap, a carabiner, or even a tent pole. This makes the Flex ideal for activities like hiking, beach trips, or biking, where portability is everything. It is also durable: with IP67 protection and a rubberized body, it can handle drops, splashes, and dust without complaint.
For everyday scenarios, the Plus is best suited for parties, extended hangouts, or as a semi-permanent speaker you move between rooms. The Flex 2nd Gen, on the other hand, feels at home outdoors and in more adventurous settings, while still working perfectly as a kitchen or desk speaker when you’re back inside.
Price and Value
Bose isn’t shy about charging for the logo, so the question is whether performance, durability, and extras justify the price. The Bose SoundLink Plus and SoundLink Flex (2nd Gen) land in two very different price lanes.
The SoundLink Plus comes in at $269, positioning itself squarely in the mid-to-high range of portable speakers. It’s meant for people who want a speaker they can rely on for years, with features like 20-hour battery life and even a USB-C charge-out function to keep your phone alive when the party runs long. In the premium portable segment, it’s competing with heavy hitters like JBL Charge 6 and Sonos Roam SL, but Bose leans hard into sound quality and brand polish to justify its price. For someone who values bigger soundstage, endurance, and multipurpose utility, the Plus earns its keep.
The SoundLink Flex (2nd Gen), by contrast, is the budget-friendly adventurer in Bose’s lineup. Retailing around $149, but often dipping to $129 or even $99 during big sales, it packs good value. At that lower price point, you’re essentially getting a rugged IP67-rated, floatable, travel-ready speaker from a premium brand at an entry-level cost. That’s why the Flex often feels like the smarter buy for people who don’t need the longest battery life or loudest output but do want dependability and portability. It’s the speaker you can toss in a backpack, take to the beach, or bring on a hike without stressing over scratches or splashes, and when it’s discounted, it punches way above its class.
The better investment depends on how you weigh sound versus lifestyle. If you want the confidence of a speaker that can power through all-day events and double as a phone charger, the Plus is worth the premium. If you care more about affordability, mobility, and ruggedness, the Flex (2nd Gen) makes a compelling case, especially when you catch it on sale.

Bose SoundLink Plus vs SoundLink Flex 2nd Gen: Which One Should You Buy?
Choosing between the Bose SoundLink Plus and the SoundLink Flex (2nd Gen) comes down to lifestyle and priorities. Both deliver the Bose audio signature, but they suit different listeners.
The SoundLink Plus is the more premium option. With its larger frame, dual-driver system, and four passive radiators, it delivers bigger, fuller sound than casual speakers. Add in a 20-hour battery life, multipoint Bluetooth with aptX Adaptive support, and the ability to double as a 15W power bank, and you have a long-haul companion that also charges your phone. It’s a good fit for anyone who wants full sound indoors, backyard parties that run into the night, or long road trips where recharging often isn’t an option. Audiophiles who want more depth and fidelity from a portable speaker will also gravitate toward the Plus, since it has the bigger soundstage and aptX Adaptive codec support.
The SoundLink Flex (2nd Gen) takes a different approach. Compact, lightweight, and designed with a built-in utility loop, it’s the go-anywhere speaker. While it doesn’t push as much volume or bass as the Plus, its sound is still well balanced, and thanks to Bose’s PositionIQ technology, it automatically adjusts based on whether you set it flat, stand it upright, or hang it on a bag. With IP67 dustproofing and waterproofing, it can survive hikes, camping trips, and beach days without breaking a sweat. At around $149 retail, often dropping to $129 or even $99, it’s also the more affordable option, making it a great value pick for students, travelers, and casual listeners who want rugged dependability without spending top dollar.
If you’re an audiophile, party host, or someone who needs all-day battery life and richer sound, the SoundLink Plus is the smarter choice. Its higher price buys better acoustics plus phone charging and codec support for higher-quality streaming. On the other hand, if you’re a traveler, outdoor adventurer, or casual listener who values portability, durability, and affordability, the SoundLink Flex (2nd Gen) is your winner. It might not shake the walls, but it will survive your backpack, pool, or camping trip while still delivering that signature Bose clarity.
Verdict: The SoundLink Plus is the better choice for those who want premium sound and battery life in a portable form, while the SoundLink Flex (2nd Gen) is the better buy for on-the-go lifestyles where portability and ruggedness matter more than raw power.

Frequently Asked Questions
Common questions about the Bose SoundLink Plus vs SoundLink Flex (2nd Gen), covering loudness, bass, waterproofing, battery life, pricing, and portability.
Is the Bose SoundLink Plus louder than the SoundLink Flex 2nd Gen?
Yes, the SoundLink Plus is louder than the SoundLink Flex (2nd Gen). With its larger driver setup (a dedicated mid/bass driver, tweeter, and four passive radiators), the Plus produces a more powerful soundstage that fills medium to large rooms with ease. It’s designed to handle higher volumes without noticeable distortion, making it ideal for parties or outdoor gatherings. The Flex 2nd Gen, while strong for its size, leans toward balanced listening in smaller to mid-sized spaces. It’s perfect for personal use, hikes, and beach outings, but if raw volume and presence are your priority, the Plus has the edge.
Which Bose speaker has better battery life, SoundLink Plus or SoundLink Flex 2nd Gen?
The SoundLink Plus wins the battery life battle with up to 20 hours of playback, compared to the Flex (2nd Gen)’s rated 12 hours. In real-world testing, the Plus often stretches close to 21 hours at moderate volume, while the Flex tends to average between 7–10 hours depending on listening levels. This difference makes the Plus better for long events, road trips, or weekend getaways where charging isn’t always convenient. The Flex’s shorter battery life is still respectable for casual daily use, but travelers and heavy listeners will appreciate the endurance of the Plus.
Is the Bose SoundLink Flex 2nd Gen waterproof?
Yes, the SoundLink Flex (2nd Gen) is fully waterproof with an IP67 rating. That means you can submerge it in up to one meter of water for 30 minutes without damage. It’s also dustproof and rugged enough to survive sand, dirt, and splashes, making it a true outdoor companion. A bonus feature is that it floats, so if it falls into a pool or lake, it won’t sink. This makes it a reliable choice for beach trips, pool parties, and camping adventures.
Does the SoundLink Plus support stereo pairing?
Yes, the SoundLink Plus supports both Stereo Pairing and Party Mode when paired with another SoundLink Plus. In Stereo Pairing, one unit acts as the left channel and the other as the right channel, creating a wide stereo image. Party Mode, on the other hand, syncs both speakers to play the same audio for a larger coverage area. This is especially useful for filling bigger spaces or outdoor environments where a single speaker might not be enough. The Flex (2nd Gen) also supports these modes but only when paired with another Flex of the same generation.
Which speaker is better for outdoor use?
If you’re going strictly by portability and ruggedness, the SoundLink Flex (2nd Gen) is the better outdoor speaker. It’s lightweight, has a built-in loop for clipping to backpacks or carabiners, and features Bose’s PositionIQ technology, which automatically adjusts sound depending on how it’s oriented. The Flex is easier to take hiking, camping, or to the beach. If your outdoor setup is more stationary (think backyard barbecues or poolside parties), the SoundLink Plus delivers more volume and deeper bass to entertain larger groups.
How portable is the SoundLink Plus compared to the Flex?
The SoundLink Plus is less portable due to its larger size and weight (over 3 pounds), whereas the Flex (2nd Gen) weighs just 1.3 pounds and easily slips into a backpack or clips to gear. The Plus feels more like a “move it from room to room or car to picnic table” speaker, while the Flex targets true on-the-go portability. If you’re looking for something to carry on hikes or long travel days, the Flex is far more convenient. If portability matters less than sound power, the Plus is still manageable but bulkier.
What’s the price difference between Bose SoundLink Plus and Flex 2nd Gen?
The SoundLink Plus retails for $269, while the SoundLink Flex (2nd Gen) retails for $149. However, the Flex frequently goes on sale for $129, and has dropped as low as $99 during big seasonal promotions. That creates a price gap of at least $120 between the two models, sometimes more. The Plus holds closer to its MSRP, rarely dipping below $249. If budget is tight, the Flex is the better value. If you can stretch your budget, the Plus delivers stronger performance and additional features like power-out charging, but it’s a much bigger investment.
Do both speakers work with the Bose Connect app?
Both the SoundLink Plus and Flex (2nd Gen) are fully compatible with the Bose Music app. Through the app, you can adjust the 3-band EQ, rename your speaker, install firmware updates, and manage multipoint connections. The app also makes it easy to enable Stereo Pairing or Party Mode between two matching speakers. For the Flex, the app enhances PositionIQ performance, while for the Plus it unlocks codec control and better sound fine-tuning. The app experience is nearly identical across both and gives more customization than the onboard buttons.
Which speaker is better for bass lovers?
For bass enthusiasts, the SoundLink Plus is the stronger option. Its larger chassis and four passive radiators deliver deeper, punchier bass that holds up even at higher volumes. It’s designed to fill space with low-end energy without overwhelming the mids. The Flex (2nd Gen) does produce respectable bass for its size, but at high volumes, Bose’s DSP reduces low-frequency output to prevent distortion, so it doesn’t hit as hard. If bass is a top priority, especially for genres like hip-hop, EDM, or R&B, the Plus is the safer bet.
Which one is the best Bose speaker for under $300?
Both models fall under the $300 mark, but they serve different audiences. The SoundLink Plus ($269) is the best pick if you want a premium Bose portable with long battery life, rich sound, and extra features like charge-out capability. It’s essentially the “all-rounder” for buyers who want high quality without jumping to the $399 SoundLink Max. The SoundLink Flex (2nd Gen) ($149, often $129 or less) is the best option for shoppers who want rugged portability and affordability without giving up Bose’s tuning. If you’re strictly asking which one is the best value under $300, the Flex 2nd Gen takes the crown when discounted, while the Plus is the best performance option under $300.
