Compare Sony ULT Field 5 Speaker vs Soundcore Boom 2 Plus Portable Speaker

The battery/status readout is a small but appreciated convenience.

Status indicator feedback was negative because battery visibility relied too much on the app or lacked an on-speaker percentage indicator.

Quick charging is consistently useful, especially the 10-minute top-up claims, though one reviewer finds it less impressive than some rivals.

Charging time drew criticism from reviewers who called the three-hour recharge long or awful when leaving soon.

Dust protection is treated as part of the speaker’s rugged outdoor appeal, especially in IP67-focused reviews.

Dust resistance was a repeated weakness because reviewers criticized the missing official dustproof rating.

The speaker has real thump, but one reviewer stresses that it does not reach subwoofer-level rumble.

The low-end hardware and passive radiators were praised for reinforcing bass and producing powerful low-frequency response.

Smart extras such as DJ controls, sound optimization, lighting, and app controls are feature-rich but sometimes gimmicky or unused.

Smart features were praised broadly in the context of the speaker's many features and sheer power.

The 10-band EQ is useful, but reviewers often note that it cannot fully recreate or fine-tune Sony’s ULT presets.

EQ customization was strongly praised across reviews for deep nine-band or full-band control and noticeable sound changes.

Battery life is widely viewed as strong for casual use, though reviewers repeatedly note that lights, ULT modes, and high volume shorten runtime.

Battery life divided reviewers: some found it good, but several called the 20-hour rating unimpressive or much shorter with lights and BassUp.

The wired AUX input is considered a useful advantage, especially versus smaller or competing models that omit it.

The aux/wired input was appreciated for easy wired playback and DJ-style setups, though one reviewer complained no cable was included.

The ULT button feels satisfying, but the other rubberized buttons are less pleasing by comparison.

Physical controls were mostly praised as reliable, responsive, and satisfying, though one reviewer wanted more button lighting.

Stereo imaging is limited by the compact driver spacing, even though some reviewers hear a wider-than-box soundstage.

One reviewer praised the size of the soundstage, but direct evidence on precise stereo imaging was limited.

On-device controls cover the basics and are easy to find, but button sounds and rubbery feel create some usability complaints.

On-device controls were praised because key functions could be accessed manually without relying on the app.

Setup can be easy for pairing and Party Connect, but Sony’s app update flow created friction in one review.

Setup was described as painless or incredibly easy.

One reviewer reports that latency is not an issue for watching videos on a phone.

Latency evidence was positive, with reviewers finding Bluetooth lag minor and movie use workable.

Most reviewers like the rugged, premium look, while a few call the rectangular design plain or boring before the lights come on.

Design feedback was mixed: reviewers liked the rugged and newer look, but some criticized the plastic as cheap or not premium.

Reviewers generally find Sony’s app useful and easy enough, but one review strongly criticizes the license, access, and update friction.

The Soundcore app was consistently described as intuitive, easy to navigate, useful, and reliable for EQ, lights, and setup.

Multipoint connectivity is useful for two people or devices sharing DJ duties without constant reconnecting.

Multipoint feedback was mixed: some reviewers liked pairing to two devices, while one outlet listed inability to pair more than one phone as a drawback.

USB-C charging is viewed positively, especially because the port does what reviewers expect and also supports related power features.

USB-C charging was mostly praised for fast charging and convenience, though one reviewer disliked that one port limited simultaneous charging.

LED lighting is usually seen as classy, customizable, and worth using, though a few reviewers find it subtle or battery-draining.

LED reactions were mixed: some reviewers loved the bright, synced show, while others found it off-beat or gimmicky.

ULT modes add energy, punch, and sound pressure, but limited headroom and compression appear when the speaker is pushed hard.

Dynamic headroom was praised by a reviewer who said the speaker handled quiet use but did loud playback even better.

The enclosure and materials earn strong marks for feeling solid, robust, and premium rather than cheap.

Build quality was generally solid, though evidence focused on material quality and cabinet feel rather than internal bracing.

Detail retrieval is mixed: some ULT modes add clarity, but bass-heavy tuning can bury small details and cymbal sparkle.

Detail retrieval was the main audio tradeoff: reviewers said detail could be lost, especially above moderate volume or in mids and treble.

Bluetooth range is generally praised, but LDAC use brings a clear range tradeoff versus AAC/SBC.

Bluetooth range drew positive comments, including apartment-to-street use, clear sound at distance, and very long outdoor connection range.

LDAC and the SBC/AAC baseline are repeatedly praised, especially for higher-quality Bluetooth audio, with some range and battery tradeoffs.

Codec support received a modest positive note because AAC made it more appealing for Apple users.

Google Fast Pair is praised for making Android connection fast and uncomplicated.

Google Fast Pair was mentioned positively as helping setup speed.

Voice and vocal clarity are mixed: vocals can cut through, but heavy bass and high volume can push voices back or roughen them.

Voice and vocal clarity ranged from muffled in bass-heavy listening to clear, well-defined mids and highs in other tests.

Reviewers see strong value when discounted or compared with smaller rivals, but cheaper alternatives still challenge it.

Value for money was one of the strongest themes, with many reviewers saying it competes with pricier speakers or is worth checking out.

Value depends on price: reviewers like it at sale or relative-to-rival pricing, but some call the MSRP steep or overpriced.

Price-value evidence was mostly positive, with some reviewers calling the speaker a strong buy or best-in-class, though one found the price costly.

High-resolution LDAC support is treated as a strength for sound quality, with a close-range caveat for the best results.

Audio format support received a modest positive mention because AAC improved usefulness for Apple users.

Low-volume performance gets direct praise from one reviewer who found 20% volume already sufficient at close range.

Low-volume performance received positive evidence, especially for retaining bass presence at reasonable or lower volumes.

Multi-speaker pairing is praised when using Sony Party Connect, especially for stable and easy syncing versus current Auracast experiences.

One reviewer who used multi-speaker linking found it reliable compared with other systems.

Reviewers generally find distortion well controlled at high levels, though this does not eliminate compression or tonal imbalance.

High-volume distortion was generally controlled, though a few reviewers noted buzzing radiators, grating highs, or reduced refinement at extreme levels.

Weight is a repeated drawback; the speaker is portable with a strap, but several reviewers call it bulky or heavy.

Weight feedback was mixed: several reviewers found it manageable for its size, while others said it was bulky, not discreet, or poor for long travel.

Water resistance gives reviewers confidence around pools, rain, splashes, and outdoor use.

Water resistance was strongly praised, with reviewers reporting pool splashes, submersion, wet use, and floatable waterproof confidence.

The power-bank function is consistently treated as handy, practical, and useful for keeping a phone alive during playback.

The power bank function was repeatedly praised as convenient for keeping phones charged during long outings.

The speaker is usually described as full, lively, and room-filling, with its bass-forward personality shaping the overall presentation.

Cohesion was generally positive when bass stayed controlled, with reviewers praising balanced, dynamic, clear, or satisfying presentation.

The lighting often improves the otherwise plain design and party feel, but at least one reviewer finds it gimmicky.

Lighting effects were generally viewed as fun and atmospheric, especially in darker rooms, though they remained secondary to audio.

Durability is a strength, with reviewers praising rugged materials, protected radiators, and resistance to outdoor bumps and knocks.

Durability evidence was positive, covering occasional tumbles, accidental impact, and protective exterior design.

Maximum volume is one of the strongest points, with many reviewers calling the speaker loud, room-filling, and party-ready.

Reviewers overwhelmingly described the speaker as very loud, with party-ready volume and bass output that worked well outdoors and in larger social spaces.

Party Connect and stereo pairing are valuable party features, but they keep users inside Sony’s ecosystem and add compatibility caveats.

Inter-speaker connectivity was viewed positively where discussed, with stereo pairing and Soundcore lineup linking considered useful.

The strap is often considered useful, strong, and convenient, although some reviewers found it fiddly or annoying to attach or remove.

The handle and strap were widely praised for comfort and portability, with only minor complaints about strap padding.

The tonal balance is bass-forward and fun, but reviewers repeatedly flag recessed mids, thin highs, or muddy bass in some tracks.

Reviewers agreed the tuning is bass-forward; some found it clear and balanced with EQ, while others said vocals or guitars could sit back.

Bluetooth stability is viewed positively, with reviewers citing a stable Bluetooth 5.3 connection and a rock-solid wireless experience.

Bluetooth connection stability was praised in app-swapping and general Bluetooth use.

The Field 5 works well for parties, yards, garages, and everyday outdoor use, as long as buyers accept its size and weight.

Everyday usability was praised when the speaker was used as intended as a party speaker.

One reviewer links the Field 5’s limited output rating to reduced headroom and compression when volume is pushed high.

Party Connect gives the Field 5 useful Sony ecosystem support, but one reviewer calls out the inability to connect it to the ULT Field 1.

Bluetooth connectivity evidence was positive from a reviewer who noted the speaker stayed connected while still audible at distance.

Party lighting is the clearest energy-efficiency complaint because it can sharply reduce playback time.

Float capability was strongly verified and praised across water tests, pool use, and outdoor scenarios.

One reviewer found the speaker effective behind a tablet or laptop for a larger movie-sound experience.

Microphone feedback was negative where discussed as a missing feature for calls or voice assistant use.

The Field 5 is not truly omnidirectional; reviewers note reduced expansiveness vertically and wish it offered 360-degree sound.

Privacy sentiment is mixed: no smart-speaker mic is a plus for one reviewer, while app access requests concern another.

One review treated the lack of microphone support for calls or voice assistant use as a negative.

Speakerphone evidence was limited but positive from SoundGuys, which found call clarity usable in ideal conditions.

The wide, detached stage can feel surround-like for a speaker of this size.
