Compare Bose SoundLink Flex Portable Speaker, 2nd Gen vs Tribit StormBox Mini+ Bluetooth Speaker

The app experience is mixed: reviewers like the simple interface and EQ access, but some call it limited and one reports firmware-update trouble.

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

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

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 respectable, with a 12-hour rating and real tests ranging from about 9.5 hours with lights and higher volume to 13 hours with lights off.

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

Bluetooth codec support is solid for the class, with repeated confirmation of Bluetooth 5.4 plus SBC and AAC support.

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

Bluetooth connection stability is consistently strong, with reviewers reporting quick pairing, stable operation, and no drops or stutters.

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

Bluetooth range is positively supported by 30m or 100ft claims and real-world notes about stable range during normal indoor/outdoor use.

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

Cabinet/exterior construction is sturdy for the price, with reviewers citing fabric weave, rugged mesh, rubberized parts, and a sturdy body.

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

Charging time is consistently around 2.5 hours, which reviewers generally frame as acceptable for this compact speaker.

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

Cohesive presentation is generally good for casual listening, with reviewers noting dynamic playback, blend, staging, and surprisingly good overall sound.

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

Control buttons are a strength overall, with reviewers praising tactile feedback, responsiveness, large buttons, and easy poolside operation.

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 broadly positive, with compact proportions, rugged fabric, a premium look, and practical portable styling.

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

Detail retrieval is better than expected for the price, with reviewers citing detailed vocals, distinguishable percussion echoes, and crisp acoustic tracks.

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

High-volume performance is mixed: one reviewer heard almost no distortion at full volume, while others reported quality dips, bass distortion, or distortion past about 80%.

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

Drop resistance has limited but positive evidence: one reviewer dropped it several times and said it continued working fine.

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

Dust resistance is weak because reviewers note the IPX rating has no dust-protection rating.

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

Dynamic headroom is limited when pushed hard because PCMag reports DSP reducing dynamic range at higher output.

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 useful strength, with app presets and custom EQ options, though a few reviewers still find the app basic.

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 for showers, travel, casual rooms, kids, backyard use, and routine listening rather than serious hi-fi use.

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

Float capability has limited but direct support from WIRED, which says the speaker floats upside down.

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 respectable for the price, especially mids and vocals, but bass depth is the most consistent limitation and one reviewer found the sound very thin.

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

The strap or lanyard is consistently useful for carrying, hanging, or clipping the speaker during travel and outdoor use.

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 a major strength; reviewers repeatedly highlight TWS or stereo pairing as a way to improve coverage and immersion.

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

The LED lighting is generally a fun, reactive, and ambient extra, especially at night or near a pool, though it remains simple.

Lighting effects are more mixed than the LED hardware itself because reviewers often mention only two modes, limited customization, or limited usefulness.

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.

Reviewers generally find the speaker loud enough for small rooms, personal outdoor use, or casual gatherings, but not for large parties or booming volume.

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

Low-volume and moderate-volume listening are generally favorable, with reviewers finding podcasts, relaxed music, and 25-50% listening clear or acceptable.

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

The built-in microphone is widely confirmed, but its usefulness varies from clear calls to backup-only or faint pickup.

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

TWS and multi-speaker pairing are a strong point, with reviewers describing the pairing as flawless, easy, or a major upgrade when using two speakers.

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

Multipoint is not supported; one review explicitly says the speaker cannot connect to a phone, laptop, or tablet simultaneously.

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

Omnidirectional sound is mostly positive, with several reviewers praising 360-degree consistency, although TechRadar found it underwhelming.

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

On-device controls are practical and well-covered, including playback, power, Bluetooth, lighting, and quick-press operation.

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 strongly positive, with reviewers repeatedly emphasizing the low price, aggressive affordability, and strong under-$40 value.

Privacy/data evidence is limited but positive because the app is said not to require an account.

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

Setup is simple across reviews, with quick pairing, no complicated setup, and easy Bluetooth connection.

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 minimal because the speaker does not rely on a smart assistant or voice platform.

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 modest: the app can handle firmware and playback controls, but the product lacks a native smart-assistant platform.

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 mixed: some reviewers report clear calls, while others say voices can sound faint or the microphone gain is low.

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

Status indicators are mixed: some buttons illuminate, but reviewers also note missing volume indication and limited battery indication.

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

Stereo improves with two speakers, but single-speaker separation is inherently limited; reviewers praised TWS separation while noting cramped or weak stereo from one unit.

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 broadly confirmed and positively noted across reviews.

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

Value for money is excellent in the evidence, with reviewers calling it surprisingly good, worth the price, and a winner for budget use.

Voice assistant access works in some tests, especially Siri activation, but one review found assistant responses too quiet.

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

Voice and vocal clarity are usually good for vocals, podcasts, videos, and spoken word, though one negative review compared it to a louder phone speaker.

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

Water resistance is one of the clearest strengths, with broad IPX7 evidence and multiple reviewers using it around showers, pools, sinks, rain, or water.

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 mixed; many reviewers find it easy to carry, but others call it heavy or weighty for the size.

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 notable strength for a small waterproof speaker because several reviews confirm a 3.5mm aux input.
