Compare Bose SoundLink Flex Portable Speaker, 2nd Gen vs Bang & Olufsen Beosound A1 Speaker 3rd Gen

Review evidence says the A1 does not support AirPlay, so Apple users still rely on Bluetooth or wired USB-C rather than Wi-Fi/AirPlay streaming.

Multiple reviews cite the dual 30W Class D amplification or 60W total output, supporting unusually strong output for the compact chassis.

The B&O app is repeatedly described as helpful, responsive, and one of the best of its kind, though one reviewer could not get built-in radio working.

Audio format support is supported by SBC, AAC, aptX and higher-quality Android streaming references.

Audio format support centers on SBC, AAC, aptX Adaptive, and USB-C wired audio rather than Wi-Fi-based formats.

Backward compatibility is weak because multiple reviewers state the second-generation model cannot stereo-pair with the original Flex.

Backwards compatibility is a strength for stereo pairing because the third-generation speaker can pair with a second-generation A1.

Battery life is adequate but not a highlight, with reviewers citing up to 12 hours and much shorter runtime at high volume or in tests.

Battery life is consistently positive, with most third-generation reviews citing 24 hours and several testers finding that figure believable or conservative.

Codec support is a meaningful Gen 2 upgrade, with reviewers citing Snapdragon Sound, aptX, SBC and AAC support.

Bluetooth codec support is strong for the class thanks to AAC and aptX Adaptive alongside basic SBC support.

Bluetooth connection stability is praised by several reviewers, with notes on Bluetooth 5.3, Snapdragon Sound, no hiccups and no disconnections.

Connection stability is generally praised, with reviewers reporting no dropouts or solid pairing, though one garden-range test eventually cut out at distance.

Bluetooth range is only lightly covered, with one spec citing 30 feet and another reviewer saying they could walk a good distance before issues.

Range evidence is moderate, with one review citing about 10 meters outdoors and another suggesting real-world limits near the end of a garden.

Cabinet construction is praised through metal or steel grille references plus rubberized, silicone or aluminum casing materials.

Construction is one of the most consistent strengths, with reviewers praising premium aluminum, polymer, finish quality, and overall craftsmanship.

Charging is a recurring weakness: reviewers repeatedly cite about four hours to recharge, which some call slow or disappointing.

Charging time is functional but not fast; several reviews cite roughly three hours and describe it as long or leisurely.

Cohesive presentation is strong overall, with reviewers describing the sound as balanced, full, clear or unexpectedly capable for the size.

The A1 is repeatedly described as cohesive, unified, controlled, and spacious rather than scattered or disjointed.

Controls are mixed: some found them easy, but SoundGuys called the buttons mushy and Android Police found touch operation confusing.

Physical buttons are generally praised as responsive, tactile, clicky, and easier to use.

Design and aesthetics are a major consensus strength, with repeated praise for the premium feel, colors, slim body and attractive grille.

Design and aesthetics are a standout consensus strength, with reviewers repeatedly emphasizing the premium, stylish, minimalist look.

Detail retrieval is a strength for the size, with reviewers hearing crisp detail, nuance and separated musical layers.

Detail retrieval is strong across reviews, especially through the midrange, vocals, and small instrumental textures.

High-volume behavior is mixed: some reviewers say Bose processing keeps distortion controlled, while others heard clarity drop or distortion at higher volumes.

Distortion control is mostly strong at higher volumes, though one review notes distortion or strain on demanding bass-heavy tracks.

Durability is strong, with reviewers citing rugged construction, drop-proof claims, solid feel and protection against outdoor abuse.

Durability is mixed: IP protection and prior-generation bump resistance help, but several reviewers warn the aluminum can scuff or may not survive rough drops like rugged JBL rivals.

Dust resistance is strongly supported by repeated IP67 and dustproof references across the reviews.

Dust resistance is strongly supported by repeated IP67 references and explicit dustproof or dust-resistant descriptions.

Dynamic headroom is supported by TechRadar's bass comments, though the broader evidence suggests dynamics are good for size rather than huge.

Dynamic performance is capable for the size but not class-leading; some reviews praise dynamism while others say rivals offer larger dynamic swings.

Energy efficiency is only lightly supported, with one reviewer noting effective sleep behavior that avoids unnecessary battery drain.

EQ customization is one of the clearest upgrades, but reviewers generally describe it as useful while limited to basic bands or presets.

EQ customization is a clear app strength, with preset modes and a visual sound control repeatedly described as useful and approachable.

Everyday usability is strong for desks, bedrooms, travel, poolside use and small gatherings thanks to the compact design and easy operation.

Everyday usability is strong because reviewers find the speaker simple to operate, portable, and easy to live with in travel, desk, shower, and small-room use.

Float capability is directly praised by multiple reviewers, who note the speaker floats if dropped in water.

Most reviewers describe the sound as balanced, clear or full, with punchy bass for the size but not true party-speaker low end.

Frequency balance is generally warm, rich, and controlled rather than strictly neutral, with impressive bass for size and some caveats around bass depth or treble impact.

Google-related support appears through Google Fast Pair, making Android pairing easier alongside Microsoft Swift Pair and Apple-focused support.

The fabric loop or strap is useful for bags and hooks, though one reviewer wanted a more flexible loop or included carabiner.

The strap is usually praised as elegant or useful for carrying, though one review notes there is no carrying case and another notes leather may not suit every buyer.

Home theater integration is limited but present through Bose SimpleSync with compatible Bose smart speakers or soundbars.

Inter-speaker connectivity is supported through Bose speaker linking, stereo mode and party mode, but compatibility limits reduce flexibility.

Inter-speaker connectivity is strong because multiple reviews confirm stereo pairing, including pairing across second- and third-generation A1 units.

Latency is mostly described positively for video and streaming, though one reviewer still noticed a minor amount of video latency.

Reviewers say the Flex 2 gets loud enough for rooms, yards and small outdoor groups, but several note it is not the loudest or best for large spaces.

Maximum volume is good for the size and small spaces but not ideal for big outdoor parties or competing with larger JBL-style speakers.

Low-volume performance is only lightly supported, but TechRadar specifically heard clearer vocals at lower volume levels.

The built-in microphone is confirmed for calls and assistant access, though call quality evidence is limited.

Microphone support is well covered, with reviews describing built-in mics, mute controls, FarField technology, and speakerphone use.

Pairing reliability is generally positive when using compatible Bose speakers, though the ecosystem is limited and not backward-compatible with the original Flex.

Multi-speaker pairing is a strength in the included reviews, especially because the app supports stereo setup and cross-generation pairing works.

Multipoint is repeatedly confirmed, letting the speaker connect to two devices or manage multiple sources through the Bose app.

Multipoint connectivity is consistently supported, with multiple reviews describing two-device pairing and one YouTube reviewer calling it flawless.

Omnidirectional sound is a weakness; Tom's Guide specifically describes strong directionality and a narrow soundstage.

Omnidirectional sound is mixed: some reviews call it 360-degree or all-directional, while others say it is not truly 360-degree and depends on positioning.

On-device controls are generally useful and complete, but touch-finding and button feel vary by reviewer.

On-device controls are well implemented, with power, pairing, volume, playback, and mic controls placed around the speaker body.

Power-bank support is absent; reviewers explicitly say it cannot charge a phone or other devices.

Value opinions are mixed: several reviewers say the quality justifies the price or sales help, while others call it expensive or a Bose tax.

Price/value is the most repeated caveat: reviewers like the product but frequently call it expensive or weaker value than JBL alternatives.

Privacy evidence is limited but positive in one review because the removal of built-in Alexa means the speaker is not always listening for Amazon voice commands.

Setup receives direct positive support from one reviewer who called it easy to set up and easy to use.

Setup is generally simple, helped by Fast Pair, Swift Pair, quick Bluetooth discovery, and straightforward operation.

The shortcut button can access a phone voice assistant, but reviewers frame this as basic phone-assistant access rather than a full built-in assistant.

Smart assistant integration is weak for the third generation because several reviews say Alexa has been dropped or is not built in.

Smart features are limited: reviewers mention app controls, shortcuts, Spotify options and voice-assistant access, but repeatedly describe the feature set as lean.

Smart features are mixed: the app adds streaming, radio, EQ, and settings, but reviewers note no Auracast, no Wi-Fi, and no Alexa on the third-generation model.

Speakerphone quality is only lightly supported, with one reviewer saying the microphone works fine for quick calls but does not sound amazing.

Speakerphone quality is a useful strength, with several reviews saying calls are clear or successful and one caller rating it highly.

Status indicators are only lightly covered, with SoundGuys noting a status light above the shortcut button.

Status indicators are functional but mixed, with LEDs present for status and charging while one review wished the indicator were larger.

Stereo and imaging evidence is mixed: two-unit stereo mode can add separation, but the single speaker is directional and not especially wide.

Stereo imaging and separation are generally good for a compact Bluetooth speaker, with reviewers praising organized soundstage and instrument separation, though scale is limited.

Sustainability is a standout feature because reviews repeatedly cite Cradle to Cradle certification, modularity, repairability, and replaceable battery support.

USB-C charging is consistently confirmed, though reviewers also note the port does not provide wired audio or power-bank output.

USB-C charging is well supported and also doubles as a wired audio/data path in several reviews.

Value for money is mixed but generally acceptable: reviewers praise quality for the price while noting cheaper rivals exist.

Value for money is mixed: some reviewers say the premium is justified by build and sound, while others say cheaper JBL or other rivals are better buys.

Voice assistant responsiveness is only supported in the older included A1 review, where Alexa setup is described as working equally well once configured.

Vocals are consistently described as clear, easy to hear or delicate, supporting strong voice clarity for music and spoken content.

Voice clarity is a recurring strength, with reviewers praising vocal intelligibility, natural vocals, and clear speech reproduction.

Water resistance is a major strength: reviewers repeatedly cite IP67 protection or water immersion suitability.

Water resistance is strongly supported by repeated IP67 descriptions and sink, beach, pool, shower, and shallow-submersion references.

The speaker is widely praised as slim, light and bag-friendly, with reviewers repeatedly saying it is easy to carry or pack.

Weight convenience is good but not perfect; reviewers find it easy to bag or carry, while noting it is not the lightest option at its size.

Wi-Fi streaming reliability scores low because reviews repeatedly say there is no Wi-Fi on board, so Wi-Fi streaming is not available to evaluate.

Wired playback is a clear weakness: reviewers repeatedly state there is no 3.5mm jack and USB-C is for charging, not audio.

Wired input is a strength on the third-generation model because USB-C can handle wired audio as well as charging.
