Compare Soundcore Boom Go 3i vs Motorola Moto Sound Flow

The companion app is described as fast, useful, and uncluttered, with enough control for EQ, pairing, groups, updates, and UWB toggles.

Backwards compatibility was a notable weakness because Auracast support did not help it work with older PartyCast Soundcore speakers.

Standard Bluetooth and Wi-Fi remain useful on ordinary phones, but the most distinctive UWB features are limited by phone compatibility, especially for older Android phones and iPhones.

Reviewers generally found battery life strong for a compact speaker, with tested or real-world results close to claims and especially long runtime in easier modes.

Battery life is viewed positively: one hands-on test found real-world drain broadly consistent with the 12-hour claim, another matched the rating closely, and a third called it suitable for long sessions.

Bluetooth reconnection is praised as quick, with remembered devices reconnecting within a second or two after waking.

Bluetooth use was praised mainly for letting two devices connect so friends can share DJ duties, though reviewers did not discuss dropouts.

Bluetooth pairing is treated as simple and quick, covering conventional portable use when Wi-Fi or UWB is not the focus.

Build quality was described as dense, durable, and reassuring despite the speaker's plastic-heavy construction.

Build and material quality are consistently framed as premium, with restrained fabric construction and materials that fit the price segment.

Reviewers viewed the overall sonic package as capable and coherent for a small speaker, with a useful mix of sound quality, build, and features.

The speaker is described as mature and cohesive, prioritizing balanced, dynamic sound and avoiding cheap loudness.

Design reactions were mostly positive for the rugged, colorful, clean look, with the main design complaint being that it cannot stand upright on its own.

Design is a major strength across reviews, with praise for the restrained cylindrical look, premium fabric, decorative presence, and neutral Pantone finishes.

Instrument separation was a repeated caveat because the small driver layout lacks the separation reviewers heard from larger or tweeter-equipped models.

Reviewers note meaningful clarity and detail, including a sense of recording space and room-filling clarity rather than volume alone.

High-volume behavior is strong overall, with one reviewer saying it stays composed at high volume despite a small treble-hot caveat elsewhere in the same review.

Durability evidence was strong: reviewers praised rugged materials, felt reassured by drop protection, and one drop test reported no functional damage.

Dust resistance was treated as part of the rugged outdoor package, giving reviewers confidence around sand, travel, and rough use.

The IP67 dust and water rating is treated as useful for outdoor use, though only one source provides an opinionated dust-related judgment.

The speaker was credited with useful headroom and clarity-first behavior at higher output, even when bass thins out.

The 30W woofer/tweeter/passive-radiator layout is credited with real headroom for the speaker's size.

Eco-oriented runtime was praised for stretching battery life substantially, though it trades away lighting and some bass energy.

EQ customization was a clear strength, with reviewers saying the app can improve or reshape the sound and offers stronger control than rivals.

EQ customization is useful for trimming treble and tailoring the sound profile, with reviewers framing it as practical rather than overwhelming.

Everyday usability was praised for grab-and-go portability, simple outdoor usefulness, and a broad set of practical extras.

Daily use is helped by the charging dock and battery behavior, with reviewers calling the dock a quality-of-life upgrade and charging/battery management low-friction.

Float capability was a weakness because one reviewer specifically noted it does not float upright like the larger Boom 3i.

Sound balance was mostly good for size, but reviews repeatedly noted tradeoffs such as reduced bass at high volume or weaker treble/detail.

The tonal balance is praised repeatedly, with deep but controlled bass, breathable mids, and detailed audio rather than a bass-heavy portable-speaker profile.

The strap was repeatedly praised for easy attachment, sturdy feel, and practical two-mode use on bags, bikes, and outdoor setups.

Inter-speaker connectivity was split: same-model Auracast pairing worked well in one test, while pairing with JBL or PartyCast Soundcore speakers disappointed others.

Inter-speaker UWB behavior is praised for automatic channel handling when two units are used, although this depends on owning multiple speakers and compatible hardware.

Video latency was praised in two reviews as not being a practical issue for phone video watching.

LED effects were consistently praised as surprisingly visible, attractive, customizable, and personality-adding for this size and price.

The LED ring is described as discreet and functional, reinforcing the premium design while communicating pairing and status cues.

Lighting effects were also valued for practical safety use, especially visibility, SOS-style modes, and nighttime outdoor activities.

Lighting effects are subtle rather than flashy, with the charging feedback described as a refined daily-use touch.

Maximum volume was considered strong for the speaker's size, though reviewers framed it as small-group or outdoor-use loud rather than party-speaker loud.

Maximum volume is strong for the form factor, with reviewers saying it fills a medium room and produces clarity as well as loudness.

Magnetic mounting was a competitive weakness because reviewers noted rival speakers offered magnetic mounting versatility that the Boom Go 3i lacks.

The lack of a built-in microphone was a repeated negative for users who want calls or speakerphone use directly from the speaker.

Microphone pickup is strong for normal home calls, with the speaker making the reviewer sound clear and natural.

Multi-speaker pairing reliability was mixed, with fast pairing between two Boom Go units but repeated frustration pairing with some other Auracast or older Soundcore speakers.

Multipoint was viewed positively because it lets two people connect and share music control.

On-device controls were considered adequate to strong, especially when they let the user manage music or lights without pulling out a phone.

The power bank feature was widely seen as a useful emergency backup, though not a full replacement for a dedicated phone charger.

Price and value were major strengths, especially at sale prices around $60 or lower, though one reviewer cautioned against paying too much more.

Despite premium positioning, one reviewer frames the product as having very few real complaints, implying the package largely supports its price tier.

Setup and pairing were described as easy or simple in the reviews that discussed the first connection process.

Setup and handoff feel highly frictionless when the required hardware is present, with UWB transfers happening without button presses or assistant commands.

Smart features were a standout, with reviewers praising the app, emergency tools, voice amplifier, lighting, timers, sound effects, and customization depth.

Smart features are seen as genuinely clever and sometimes futuristic, but the consensus is tempered by UWB compatibility limits and multi-speaker requirements.

Speakerphone capability was a weak point because reviewers emphasized that competitors have call microphones while the Boom Go 3i does not.

Speakerphone quality is good for one-on-one home calls, with clear voice pickup, though it is not positioned as a full conference-room replacement.

Status indicators were appreciated for the digital battery or mode display, making the speaker feel more informative than simple LED-only rivals.

Status feedback has a notable weakness because battery level is not shown on the speaker itself and requires the companion app.

Stereo presentation is praised for perceptible channel separation and a sense of spatial width and depth from a portable form factor.

USB-C charging was useful as a practical charge-and-power-bank port, with one reviewer confirming phone charging worked right away.

USB-C charging is valued as a practical fallback to the dock, making travel or emergency charging easier with a power bank or laptop charger.

Value for money was strongly positive across reviewers, who described the speaker as a good buy or big bang for the buck.

Overall value is positive within intended use cases, with a recommendation grounded in sound quality, materials, and practical execution rather than low pricing.

Voice clarity in music was praised through well-pronounced vocals, and the voice-amplifier feature was seen as surprisingly useful.

Vocal clarity is praised, with vocals described as present and breathable without becoming shouty.

Water resistance was viewed as confidence-building for pools, hikes, outdoor travel, and rough conditions.

Water resistance is treated as a useful outdoor and poolside strength, supported by IP67 comments and positive splash/poolside framing.

Weight convenience was positive overall: one review noted it is heavier than a Bose rival but still easy to carry or pack.

Wi-Fi streaming is praised for home use, with one reviewer specifically valuing its quality and stability.

Wired input was a weakness because reviewers stated the USB-C port cannot be used for wired audio, although one did not consider that a major issue at this size.
