Compare Sony ULT Field 5 Speaker vs JBL Go 5

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

The raised physical controls are simple, familiar, and quick to respond. Reviewers report near-instant reactions from both the buttons and companion app.

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

Portability is one of the strongest points: the Go 5 fits in pockets, bags, and backpacks and is easy to carry all day. A few Go 4 comparisons note that it is slightly heavier or bulkier.

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

AirTouch, Auracast, app-based EQ, lighting control, firmware updates, and USB-C audio make the Go 5 unusually sophisticated for its size. The feature set is a major reason it feels more mature than a basic budget speaker.

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

A single Go 5 remains a focused mono speaker with limited width. Two units paired through AirTouch create a much wider, believable left-right image and noticeably clearer presentation.

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

The edge LEDs can serve as status cues and add personality, but color choice is fixed to the speaker finish. Dark-room users object to flashes that cannot be completely suppressed.

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.

Auracast can synchronize the Go 5 with several current JBL models, including the Go 4. AirTouch stereo requires two Go 5 units, and older PartyBoost speakers are excluded.

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

Vocals, podcasts, and spoken content come through cleanly and prominently. Reviewers especially praise clear mids and crisp speech from such a small enclosure.

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

Reviewers hear clean mids, crisp highs, defined instruments, and musical details that are easy to miss on lesser mini speakers. Fine separation is still constrained by the single small driver.

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

The physical playback, volume, Bluetooth, and Auracast controls are straightforward and dependable. Familiar JBL layouts help returning users operate it immediately.

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

A full charge generally takes about 2.5 to three hours. Some reviewers find that acceptable, while others consider it slow for a small battery.

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

Reviewers value the upgraded dust protection for beaches, hiking, and outdoor travel. IP68 coverage is repeatedly treated as a meaningful durability improvement.

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

The Go 5 is a directional mono speaker rather than a true 360-degree design. It is adequate for personal listening, but omnidirectional rivals may serve groups better.

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

The seven-band EQ is one of the most useful app features and can meaningfully improve bass, vocals, or room tuning. One customer calls it gimmicky, and it becomes unavailable when two speakers are stereo-paired.

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

Range testing is strong, including stable playback through walls, closed doors, and multiple floors. The connection generally holds farther than reviewers expected from a speaker this small.

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

Several reviewers find the Go 5 cleaner than expected when pushed, with little obvious distortion. Others hear harsh mids, compression, or mild bass distortion at the highest settings.

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

Support for 24-bit/48kHz lossless playback over USB-C is a standout capability at this size and price. Reviewers hear modest improvements in clarity and detail when using wired playback.

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

The Go 5 sounds punchy and energetic at sensible levels and stays more composed than the Go 4 when pushed. Its tiny driver still limits large-scale dynamics and deep impact.

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

The integrated loop is handy for bags, bikes, and one-finger carrying. Several reviewers wish it were more elastic or included a carabiner for easier attachment.

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

Lighting is the most polarizing feature: many users find it tasteful, fun, or useful at night, while others call it gimmicky, distracting, or impossible to fully disable. Limited color customization is a common complaint.

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

Most reviewers describe the JBL Portable app as stable, clean, responsive, and useful for EQ, lights, updates, and grouping. One customer experienced failed connections, lengthy troubleshooting, and a highly frustrating setup.

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

AirTouch is a standout feature, making two-speaker stereo pairing almost instant, while Auracast supports larger JBL groups. True stereo requires two Go 5 units, and older PartyBoost products are not fully compatible.

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

The dense build survives rough handling, dirt, concrete, and several real-world drops in the supplied reviews. It is consistently described as rugged, solid, and easy to carry without babying.

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

The tuning is generally warm, clear, and mid-forward, with clean highs and enjoyable bass for the size. Deep lows remain limited, and Playtime Boost can make the balance thin.

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

Google Fast Pair makes Android setup quick and nearly effortless.

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

One customer reports that USB-C charging is quick. The broader complaint is not the charging method itself, but that no cable is included.

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

The Go 5 sounds composed, full, and musically coherent for its size. Its tuning favors an engaging overall presentation over analytical precision.

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

AirTouch and Auracast pairing are usually fast, synchronized, and reliable. One customer reports more difficult cross-generation pairing and repeated Bluetooth loss with older Go 4 units.

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

IP68 protection is a major strength, with reviewers confidently using the speaker near pools, in showers, in rain, and after submersion. Multiple hands-on accounts describe water exposure without damage.

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

Typical expectations are about eight hours, or up to ten with Playtime Boost, and many users find that adequate. Real-world reports range from roughly four to nine hours, while the boost mode noticeably reduces bass and sound quality.

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

The Go 5 plays surprisingly loud for its palm-sized body and works well for desks, showers, job sites, and small gatherings. It still cannot replace a larger room-filling speaker, and some reviewers hear strain near maximum output.

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

The overall consensus is that the Go 5 delivers excellent sound, ruggedness, and connectivity for the money. Value weakens for existing Go 4 owners, buyers who need longer battery life, or those frustrated by missing accessories.

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

Multipoint support makes switching between a phone and laptop straightforward and lets two people share playback control.

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

Bluetooth setup is usually quick and intuitive, with Fast Pair and AirTouch reducing friction further. One customer had a severe app-connection problem that required hours of troubleshooting.

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

The compact fabric-wrapped design feels premium, colorful, and rugged, with many buyers praising its looks. The fixed-color lighting and slightly larger Go 4 footprint divide opinion.

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

Most experts consider the launch price affordable for the sound, durability, and feature set. A few reviewers think roughly $55 is high for such a small speaker, especially without a cable.

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

The speaker works especially well for desks, kitchens, showers, travel, commuting, work, biking, and casual outdoor use. Its small size and simple controls make it easy to use without planning.

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

Support for SBC, AAC, and LC3 is viewed as modern and useful, especially for efficiency and stability. Reviewers do not present it as audiophile-grade, but it is strong for the category.

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

Some reviewers praise the app for working without forced registration. One customer reports mandatory account setup and data sharing, creating a sharply conflicting privacy experience.

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

At low and moderate volume, the speaker remains clear and works very well for background music, podcasts, and close listening. Several users specifically praise bass and clarity at quieter levels.

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

The edge lights provide helpful cues for volume, power, pairing, battery, and Auracast. The same persistent status flashes can be annoying in dark rooms.

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

USB-C audio provides clearer lossless wired playback from compatible devices, an uncommon bonus in such a small budget speaker. Activating it requires holding the play button while connecting the cable, so the process is easy to miss.

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

Playtime Boost can extend runtime by roughly two hours, but it does so by reducing bass and flattening the sound. Reviewers generally treat it as an emergency setting rather than the preferred listening mode.

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

Most testing reports seamless pairing, no dropouts, and stable playback through walls. A minority report problems when mixing the Go 5 with older JBL speakers.

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

One reviewer reports no noticeable delay when watching video from a phone. Broader TV-specific testing is limited.

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

Bass is punchy, clean, and fuller than expected for the size, especially after EQ adjustment. Deep sub-bass and room-shaking impact are absent, and Playtime Boost weakens the low end substantially.

Pairing is generally fast and easy across phones, laptops, and Android Fast Pair. The basic wireless experience is polished and accessible.

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

The box omits a USB-C cable or charger, and this is one of the most repeated customer complaints. Several buyers still like the speaker but lower their rating or question the value because basic charging accessories are absent.

One customer specifically misses Chromecast and considers its absence a meaningful limitation. No reviewer reports native Chromecast support.

The speaker lacks a built-in microphone, so it cannot natively handle calls. Reviewers treat this as a minor-to-moderate omission rather than a deal breaker.

The dominant view is that the Go 5 sounds exceptionally good for a palm-sized speaker, with clear mids, crisp highs, and lively tuning. It remains best for casual listening rather than critical or large-room playback.

Most buyers are highly enthusiastic about the compact sound, portability, and ruggedness. A smaller group is strongly dissatisfied because of lighting behavior, app setup, or missing accessories.

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

A single Go 5 is well suited to desks, kitchens, bathrooms, hotel rooms, and other modest spaces. Unavoidable light flashes can make it less appealing for dark bedrooms or movie watching.

The Go 5 has no built-in speakerphone function, which some reviewers list as a clear drawback. It cannot handle calls without a separate microphone accessory.

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.

Recycled fabric, plastic, magnet materials, and simpler cardboard packaging receive positive attention. Reviewers see these changes as meaningful in a high-volume product line.
