Compare Sony ULT Field 5 Speaker vs Dali Katch G2 Portable Speaker

One review found the app mostly well-designed, while another found the setup and update flow frustrating.

Party Connect compatibility extends to older Sony portable speakers, making expansion inside Sony’s ecosystem easier.

The auxiliary input keeps older gear in play, with reviews specifically mentioning legacy devices such as older iPods and other wired sources.

Reviews repeatedly cite roughly 25 hours in lighter-use conditions, with shorter runtime implied once output and extras increase.

Battery life was one of the clearest strengths in the supplied reviews, with a 30-hour figure repeatedly called out in very positive terms.

Bluetooth support for SBC, AAC, and LDAC is consistently called out across reviews.

Codec support was a clear plus, with reviews repeatedly mentioning aptX HD and related Bluetooth audio support.

The speaker emphasizes stable Bluetooth behavior, with a stability-first mode and positive comments about reliable connection behavior.

One reviewer explicitly described the Bluetooth performance as very good, though no long-range or multi-device stability testing was discussed.

Range is generally described as good, though one reviewer warns LDAC does not carry as far as AAC/SBC.

Reviews repeatedly praised the Katch G2's construction quality, emphasizing its metal-heavy build, premium finish, and sturdier feel than many rivals.

Quick charging is a real strength, with reviewers repeatedly citing about 100 minutes of playback from a 10-minute charge.

One review said the battery can go from empty to full in roughly two hours, which was treated as reasonably quick even without fast-charge tricks.

One review describes the overall sound as consistent and cohesive even if it is not the most resolving.

Positive reviews described the presentation as controlled, easy to listen to, and musically coherent rather than aggressively hyped.

Controls cover the basics well, but the dedicated ULT button feels better than the softer rubberized keys.

The top-mounted controls were described as clicky and doing exactly what users would expect.

The design is rugged and clean but visually plain to some reviewers, with finish and lighting doing much of the personality work.

Design was one of the strongest recurring positives. Reviewers repeatedly highlighted the speaker's classy, distinctive industrial styling.

Fine detail is not a strength here, and upper-register elements can get lost in the mix.

Detail and nuance were major strengths in the positive reviews, which praised the speaker's resolution, textural insight, and ability to separate musical elements clearly.

Reviews generally say it stays controlled at high output, with little obvious distortion even when bass boost is active.

High-volume behavior drew criticism. One review said the bass gets woolly and congested when really cranked, while another said the speaker can become unlistenable near maximum due to audible pumping.

One reviewer explicitly says the speaker still looked good after bumps and knocks, reinforcing the rugged-build theme.

One reviewer described the Katch G2 as built like a tank, suggesting strong physical robustness, though no formal drop testing was discussed.

Dust resistance is a clear strength, with direct IP67-style outdoor protection references.

One review explicitly stated that the speaker has no dust resistance.

It gets loud, but review evidence also points to compression and reduced openness once volume is pushed harder.

The Katch G2 can sound dynamic and room-filling, but one reviewer said headroom changes versus the prior model were limited and high-volume control is not perfect.

One reviewer specifically criticized the party lighting for poor power efficiency.

The app provides a 10-band EQ, though reviewers note it cannot fully replace or match the built-in ULT presets.

EQ control is limited. Reviews noted that users are restricted to onboard presets rather than deeper custom tuning.

Review evidence frames the speaker as practical for regular indoor/outdoor use, not just occasional parties.

The Katch G2 was described as easy to use in daily life, with simple controls, stable footing, and a handle that makes moving it around the house easier.

The tuning is engaging but not neutral, with bass emphasis often overshadowing mids and highs even though some heard a fairly balanced baseline.

Some reviews praised the sound as smooth, refined, and not harsh across the range, but one critical review found it thin, bright, and brittle at higher levels.

Google Fast Pair support is explicitly mentioned.

The included strap is useful and solid, but attachment convenience is mixed depending on the reviewer.

The hidden handle was a standout design feature, praised as clever and useful, though one reviewer noted some stiffness.

Stereo pairing and large-scale Party Connect support are recurring strengths for bigger setups.

Stereo pairing with a second Katch G2 was mentioned across several reviews and presented as a meaningful expansion option.

One reviewer measured Bluetooth latency at about 50 ms and described it as about as good as it gets in testing, suggesting strong sync performance.

LED effects are bright and customizable, adding obvious party appeal.

The lighting is designed to pulse with the music and reinforce the speaker’s party identity.

High output is one of the clearest strengths, with multiple reviewers emphasizing how loud and party-ready it gets.

The speaker can play surprisingly loud and fill sizable rooms, though one reviewer only found a small loudness advantage over the prior generation.

At low listening levels, one reviewer still found the sound full and satisfying at close range.

One review explicitly argued that the speaker makes more sense at lower listening levels, where its clarity is easier to appreciate before high-volume shortcomings dominate.

The speaker includes microphones for calls, but the reviews do not go deep on call quality.

One reviewer explicitly describes Party Connect as more stable and easier to use than a competing multi-speaker system.

Two-device multipoint pairing is repeatedly called out across reviews.

One reviewer specifically notes that this is not a 360-degree or omnidirectional speaker.

Drivers on both sides and 360-degree behavior were explicitly mentioned, supporting a broader sound spread than a simple front-firing design.

The on-speaker controls cover the main actions clearly and are easy to access.

On-speaker operation is central to the experience, with reviews noting physical buttons for power, volume, Bluetooth, and EQ selection.

The USB-C port can charge external devices, and multiple reviews present that as a meaningful convenience feature.

The speaker can charge another device, and that power-bank behavior was explicitly mentioned in two reviews.

Direct value comments are favorable, describing the speaker as well-priced or affordable for what it offers.

Value was highly price-sensitive in the supplied reviews. One review said it was worth a look around £299, while another called it one of the worst values at its asking price.

One reviewer specifically praised the lack of smart-speaker creep from a privacy/security angle.

Basic pairing is described as quick and uncomplicated.

Reviews framed the speaker as straightforward to set up and operate, thanks to its simple control layout and app-free approach.

One reviewer explicitly says it is not a smart speaker, so assistant integration is essentially absent.

Lighting control, EQ, DJ tools, and sound field optimization give it a robust feature set for a portable speaker.

Reviews portrayed the Katch G2 as intentionally simple rather than feature-rich, with no app and little extra smart functionality.

The speaker provides direct battery-status feedback, which adds convenience in daily use.

It offers some stereo capability, but several reviewers say separation and stereo effect remain limited.

Supportive reviews described stable separation and a real sense of left and right that feels bigger than the enclosure suggests.

USB-C charging is explicitly mentioned for recharging the speaker.

USB-C charging is absent. Reviews explicitly said the Katch G2 uses a barrel-style charger instead.

Value looks more mixed at varying street prices, with one review calling it overpriced and another calling it not too expensive.

Perceived value varied sharply by reviewer and price context. At roughly £299 it was seen as worthwhile, but another review judged it very poor value overall.

Vocal clarity is serviceable but inconsistent, with some reviewers hearing good cut-through and others hearing roughness or masked mids.

One music-focused review highlighted clear, recognizable vocals with a smooth presentation.

Water resistance is a core strength, with repeated IP67 or IP66/IP67-style mentions for outdoor use.

Multiple reviews said the speaker lacks meaningful water protection or an IP rating, making it a poor fit for the beach, pool, or other wet environments.

Multiple reviews flag the weight as noticeable, bulky, or less bag-friendly than smaller portable speakers.

Portability is helped by the handle, but reviewers still described the speaker as heavy, brick-like, or slightly heavier than the original.

A 3.5 mm analog/AUX input is repeatedly cited as a useful advantage.

The 3.5mm auxiliary input was consistently treated as a plus, especially for connecting older or wired source devices.
