Compare LG xboom Bounce Core by will.i.am Portable Speaker vs Marshall Willen II

Reviewers cite the 10W full-range driver and, in some sources, a 38W amplifier as impressive for the speaker's very small body.

ThinQ app experience is a major split point. Several reviewers criticize account/permission demands, pairing friction, and unreliable or confusing extra features, while at least one describes the newer ThinQ approach as improved versus older LG apps.

The Marshall app is described as solid, though reviewers focus more on its limited feature depth than reliability problems.

Audio format support is limited because reviewers note the lack of high-resolution audio support, though they do not frame it as a major issue for this size.

Backwards compatibility is mixed: the lack of wired audio hurts older-device use, and one reviewer notes the older Willen had stack features this version lacks.

Battery life is widely praised and frequently cited at up to 30 hours under favorable conditions. Multiple reviews note meaningful reductions when lighting and bass/AI features are used heavily.

Battery life is one of the clearest strengths, with reviewers repeatedly reporting about 14 to 17-plus hours depending on volume and use.

Codec support is described as limited, with coverage pointing to AAC and SBC rather than broader high-quality codec options. This can matter for listeners sensitive to compression artifacts.

Standard Bluetooth playback is often described as stable and painless, but at least one source reports a notable bug around audio after phone calls. Overall stability seems good, with edge-case issues noted.

Bluetooth stability is consistently praised, with reviewers noting stable connections, strong range, and music that does not cut out nearby.

Range is a stated strength in the reviews that measured or cited it, ranging from 100 meters to an unusually long 240 meters.

Build quality is a major strength: reviewers repeatedly describe a robust, dense, rugged speaker with premium-feeling materials.

Charging time is repeatedly described as about three hours for a full charge, which is competitive given the large claimed runtime.

Charging is strong for travel use, especially the repeated claim that about 20 minutes of charging gives roughly five to five and a half hours of playback.

Overall presentation is one of the most divisive areas. Some call it immersive and vibrant, while others find it shallow, empty, or muddled, especially when AI modes or bass-forward tuning dominate.

The Willen II is consistently described as balanced, clean, warm, and coherent rather than bass-heavy or party-focused.

Reviewers like the Marshall joystick control because it feels intuitive, solid, and easier than common multi-press button layouts.

Design impressions range from sleek and modern-boombox to rugged and utilitarian. Strap integration and the light strip are frequently praised, while some criticisms include wobbly feet, hard-to-see buttons, or a less refined look indoors.

Design is one of the broadest points of agreement: reviewers praise the retro Marshall amp look, rock styling, and premium finish.

Detail performance is inconsistent: some find it separates layers well at the right volume, while others describe loss of nuance and a blended, compressed presentation. Codec limitations and tuning choices are repeatedly implied as contributors.

Detail retrieval is repeatedly praised for the size, with clear highs, audible detail, and better instrument texture than expected from a tiny speaker.

Dialogue clarity is supported through the Voice preset, which reviewers describe as useful for podcast and audiobook dialogue.

High-volume performance is mixed: some reviewers find it holds together well, while others report harshness or fuzzing/strain when pushed near max volume. Multiple sources imply a sweet spot below maximum output.

High-volume behavior is mixed: several reviewers praise clarity and low distortion, while others mention vibration, tinny sound, or limited output.

Ruggedness is a highlight: multiple sources reference military-standard testing alongside strong build protections. It is commonly portrayed as a speaker you can use outdoors without babying.

Only one review directly supports drop durability, saying both tested speakers survived drops without damage.

Dust resistance is consistently described as part of its IP67 rating, positioning it as a solid choice for beach, camping, and general outdoor exposure.

Dust resistance is consistently supported through the Willen II's IP67 dust and water resistance rating.

It has strong output headroom for parties, but several reviews imply the best quality sits below maximum volume. Pushing too hard can trade refinement for loudness.

Dynamic headroom is respectable but not unlimited; reviewers praise preserved clarity at higher volumes while also noting output limits.

Energy efficiency is supported by Bluetooth 5.3 comments and its connection to longer battery life and improved connection strength.

EQ options are a clear strength: multiple presets plus a custom six-band EQ are repeatedly mentioned. AI Sound is frequently described as hit-or-miss, with some finding it adds depth and others finding it inconsistent or degrading clarity.

EQ customization is limited: reviewers repeatedly note three presets and the lack of a full custom EQ.

Everyday usability is strong for portable, desk, travel, backpack, and outdoor scenarios, though not always for larger group playback.

Tonal balance is polarizing. Some praise strong bass that does not overwhelm and call mids/treble clear, while others hear bass-forward tuning with compressed mids/highs and an empty or dull presentation.

Frequency response balance is one of the Willen II's strongest sonic traits, with reviewers describing flat, accurate, balanced tuning.

No summary yet.

The strap is a signature feature that many like for carrying or hanging, but multiple reviews also flag it as potentially flimsy or prone to deformation over time. Practical, but not universally trusted as long-term rugged hardware.

The rear strap is usually praised as handy and discreet, though one review finds it flimsier than the rest of the build.

Inter-speaker connectivity is a key feature via Party Link/Auracast concepts, enabling stereo or group playback with compatible devices. Some limitations are noted around how features are accessed and managed through the app.

Inter-speaker connectivity is future-looking rather than fully proven; reviews mention Auracast but also note it was not active or dependable yet.

Latency is only lightly supported, but one review credits Bluetooth 5.3 with keeping latency to a minimum.

The LED light strip and patterns are a major part of the product identity, with options ranging from subtle mood lighting to party-style effects. AI lighting is praised by some and dismissed by others as inconsistent or underwhelming.

Across reviews, it gets very loud and is repeatedly positioned as an outdoor/party-capable speaker that can fill a room or backyard. Several note the sound comes alive best at moderate-to-higher volumes.

Maximum loudness splits reviewers: some call it enough for small groups or hit high dB readings, while others find it quiet for the price.

Low-volume listening can sound flat or lacking treble presence according to at least one detailed evaluation. Multiple sources suggest it benefits from being turned up to reach its best balance.

The built-in microphone is a useful extra for calls, mentioned positively as a feature absent from some rivals.

It supports multi-speaker modes (Party Link/Auracast), and most coverage treats pairing as a key capability. A recurring caveat is that some grouping behaviors and mode exits can be app-dependent.

Multi-speaker pairing reliability is weakly supported and negative, with one reviewer warning not to rely on the promised features.

Multipoint support is explicitly noted, making it easier to switch between two connected devices. No major downsides are highlighted beyond the broader Bluetooth feature limitations.

Multipoint support is explicitly mentioned in one overview: it can pair with up to eight devices and be used with two at a time.

Omnidirectional sound is not a strength; one review notes listening changes when moving around or positioning the speaker differently.

No summary yet.

On-device controls are a highlight, especially the joystick for volume, playback, and track changes, plus clear top buttons.

Reverse charging is called out as a useful extra for outdoor use, letting the speaker top up a phone in a pinch. Reviewers imply it is convenient but will reduce total playback time.

The Willen II lacks a power-bank function, which reviewers mention as a missing feature compared with some rivals.

Price reactions are mixed: some reviewers call it worth the premium, while others think it is expensive versus louder or cheaper competitors.

Privacy concerns are raised around ThinQ requiring an account and requesting personal data and permissions (including location). This is framed as disproportionate for a Bluetooth speaker by at least one reviewer.

Basic Bluetooth setup is generally described as easy, but the app-driven setup and device-adding workflow can be time-consuming and frustrating depending on the reviewer.

Setup appears simple, with pairing described as quick, painless, and trouble-free in the review that directly addresses it.

Smart extras include AI lighting, AI sound, and space-based calibration plus the programmable heart button. The concept is widely discussed, but reliability and usefulness vary sharply by reviewer and depend heavily on ThinQ.

Smart-feature depth is modest: the speaker offers app presets, battery options, mic support, and promised Auracast, but not much more.

Speakerphone performance is mixed. Some report clear calls and strong noise handling, while at least one detailed review finds the mic overly processed with noticeable artifacts.

Speakerphone support is functional rather than deeply tested, with reviews noting button call controls and phone-call use.

Lighting is used for functional feedback as well as aesthetics, including indicating Bluetooth status/connection modes in addition to decorative patterns.

Status indicators are clear and useful, especially the LED battery indicators that show remaining charge directly on the speaker.

It delivers some stereo width (often described as subtle), but the stage can feel narrow or crowded compared with class leaders. Several reviewers still prefer it to mono-style portables for separation.

Stereo imaging is limited by the tiny single-speaker form factor, with one review saying instrument separation is not spectacular.

USB-C is the standard charging method and is consistently highlighted as the primary port. It is also tied to reverse charging in some coverage.

USB-C charging is consistently confirmed through the included cable, side port, and explicit charging descriptions.

Overall value is context-dependent: strong for design, build, battery, and balanced sound, weaker if buyers want maximum loudness per dollar.

Playback vocal clarity varies by reviewer and volume: some report clear, central vocals, while others describe muddiness and difficulty picking out lyrics in denser mixes.

Voice and vocal clarity are a repeated strength, with reviewers describing vocals as clear, crystalline, and not muddy.

It is repeatedly described as IP67 water resistant, suitable for rain, splashes, and rough outdoor use. Reviewers frame this as a core strength for poolside and backyard listening.

Water resistance is well supported across reviews through the IP67 rating and repeated pool, beach, rain, and outdoor-use comments.

Portability is debated: some call it manageable for car, patio, and moving around home, while others find it too heavy/bulky for backpacks or true grab-and-go use.

Weight is still portable, but the Willen II has noticeable heft for its size; reviewers frame that weight as manageable and premium-feeling.

Wired input options are minimal. Reviews consistently describe USB-C as the only physical connection and note there is no 3.5mm aux input for legacy devices.

Wired input is a clear limitation: reviews repeatedly say USB-C is not for wired audio and there is no AUX input.
