Compare Sony ULT Field 5 Speaker vs Sonos Roam 2 Portable Bluetooth Speaker

AirPlay support was treated as a useful advantage, especially for Apple users and multi-room playback, though most reviews mentioned it as part of the broader Wi-Fi feature set.

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

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

App reliability was one of the most divided areas: some reviewers found it easy and useful, while others reported setup hurdles, dead controls or broader Sonos app frustrations.

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

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.

Backward compatibility was positive where mentioned, with the Roam 2 able to pair with the original Roam for stereo use.

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 was the most common weakness: ten hours was enough for casual outings, but many reviewers said rivals last longer and that Sonos should have improved it.

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

Bluetooth codec support was criticized as limited, with repeated notes that the speaker only supports SBC and AAC despite its premium price.

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

Bluetooth stability was strong in hands-on testing, with reviewers reporting seamless switching or no dropouts over long use.

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

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

Cabinet and build construction were praised as metal, solid, rugged and premium for a compact portable speaker.

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

Charging speed received limited but positive evidence, mainly around the newer USB-C cable helping the Roam 2 charge faster than its predecessor.

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

Cohesive presentation received direct praise for fullness and cohesion, especially in rock and hip-hop playback.

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

The new dedicated Bluetooth button and physical controls were widely praised for making pairing and daily use easier than the original Roam.

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

Design and aesthetics were broadly praised as sleek, minimal, premium and packable, though one review found the matte black exterior prone to smudges and scratches.

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

Detail retrieval split reviewers: many heard clear instrument separation, while more critical reviews said rivals reveal more nuance and subtlety.

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

High-volume behavior was mostly praised for staying clean, though some reviews noted performance limits or bass thinning when pushed hard.

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

Durability was generally praised, including rough handling, beach use and accidental drops, though one review noted the lack of large rubber bumpers.

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

Dust resistance was praised mainly in outdoor and beach contexts, where reviewers valued the IP67 protection against sand and dirt.

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

Dynamic headroom was limited at high volumes because processing can reduce bass and dynamics to avoid distortion.

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

Energy-saving behavior was viewed positively through sleep and battery-conservation features that help preserve charge between uses.

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 useful but basic: reviewers liked bass and treble controls, while several wanted more than the simple two-band adjustment.

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 strong thanks to compact size, easy Bluetooth pairing, physical controls and the ability to move between home and outdoor listening.

Float capability was a clear drawback: reviewers liked the waterproofing but noted that it sinks unlike some outdoor rivals.

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

Sound balance was one of the Roam 2's strongest areas, with repeated praise for clear, full and balanced playback for its size, offset by some criticism of bass limits and refinement.

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

Google support was a consistent weakness where mentioned, with reviewers noting that Google Assistant is no longer available.

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

The lack of a strap, loop or carry attachment was a repeated portability complaint despite the compact body.

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 a major strength, with praise for Sonos grouping, Sound Swap, AirPlay-style extension and seamless ecosystem integration.

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

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

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

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

Reviewers generally found the Roam 2 louder than its small size suggests, but several said it is not a true party speaker and can trail larger rivals outdoors.

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

Low-volume or moderate-volume listening drew positive evidence, with one reviewer not needing more than half volume indoors.

Microphone support was mixed: it enables voice features and Trueplay, but reviewers called out limitations around speakerphone use and Bluetooth mode.

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

Stereo pairing and multi-speaker pairing were praised when used through Wi-Fi, but Bluetooth-only pairing limitations kept this from being universally flexible.

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

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

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 for tactile playback, volume and grouping functions, especially because they remain usable around water or without relying on the app.

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

Power bank functionality was a limitation because the Roam 2 does not support reverse charging.

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

Price and value depended heavily on Sonos ecosystem use: reviewers saw the premium as justified for Sonos features but steep against cheaper Bluetooth rivals.

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

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

Setup simplicity improved sharply for Bluetooth use, with many reviewers praising out-of-box pairing; Wi-Fi setup through the app was less consistent.

Alexa and Sonos voice features were useful on Wi-Fi, but Alexa limitations and the absence of Google Assistant kept smart assistant support from being perfect.

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

Smart features were valued for synchronized Sonos playback, voice control and app-based service aggregation, especially inside an existing Sonos home.

Speakerphone capability was a weak point because reviews noted that the Roam 2 cannot be used for phone calls or conference calls.

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

Status indicators were a minor usability weakness, with reviewers wanting larger lights and a clearer battery indicator.

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

Stereo impressions were mixed: the Roam 2 itself is mono, but pairing two units over Wi-Fi can create noticeably better separation.

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

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

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

USB-C charging was generally positive, especially the included USB-C to USB-C cable, though one review criticized pricey wireless charging accessories rather than the port itself.

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

Value for money was mixed: the Roam 2 felt worthwhile for Sonos users and premium sound seekers, but less compelling against cheaper or longer-lasting alternatives.

Voice assistant responsiveness was a bright spot in positive reviews, especially Sonos Voice Control working hands-free and even over Bluetooth for basic commands.

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 reproduction was usually clear and warm, though at least one reviewer preferred a rival for clearer vocals.

Voice recognition was praised in the few reviews that tested Sonos Voice Control, with requests reportedly understood reliably.

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

Water resistance earned strong praise, with reviewers reporting successful use around showers, beaches, dunking, splashes and rinsing.

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

Weight and portability were consistently praised, with reviewers emphasizing that it is light, packable and easy to carry around the house or outdoors.

Wi-Fi streaming and Sonos ecosystem integration were repeatedly described as reliable, seamless or central to the product's appeal.

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

Wired input was a clear limitation, with the USB-C port described as charging-only rather than an audio input.
