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

Reviewers repeatedly describe the Boom 2 Plus as a high-output portable speaker, with 100W normal operation and up to 140W with BassUp. The power is consistently tied to party use, strong bass, and outdoor loudness rather than quiet hi-fi listening.

The Soundcore app is generally described as intuitive, clean, and useful for EQ, lighting, firmware, and basic controls. One review noted an early beta/prerelease state, but most comments support reliable everyday app usability.

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

Codec and format evidence is limited but specific: reviewers mention Bluetooth playback with SBC and AAC support. They do not describe advanced hi-res Bluetooth codecs, and one review notes the lack of AptX for high-resolution playback.

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

Battery life is usually stated around 20 hours under moderate conditions with BassUp and lights off. Reviewers consider that usable for a day out, but several call it unimpressive versus rivals or note that loud playback and lighting reduce it substantially.

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

Codec support is presented as serviceable rather than premium. Reviews cite SBC and AAC, which helps Apple users, but there is no evidence of LDAC, AptX, or broader audiophile codec support.

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

Bluetooth stability is strong in the available evidence. Reviewers report reliable Bluetooth 5.3 pairing, steady playback, and no problems moving between common streaming apps.

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

Range receives positive evidence from real-world use, including long-distance connection claims and reviewers walking far from the speaker while it stayed connected.

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

Build quality is mixed but mostly practical: reviewers describe robust plastic housing, solid construction, and good protection, while also noting the enclosure can look or feel cheap compared with more premium rivals.

Charging is repeatedly described as USB-C fast charging with a roughly three-hour full charge time. Some reviewers see that as convenient, while others call the overall charge time long if the speaker is depleted before leaving.

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

The speaker’s presentation is generally cohesive for its party-speaker role, especially at moderate volumes. Reviewers praise clarity and balance, but the bass-forward tuning can dominate the mix depending on volume, placement, and BassUp.

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

Physical controls are generally praised for tactile response and clear icons, though one reviewer wanted more button backlighting. The top-mounted layout covers core playback, Bluetooth, lighting, PartyCast, and BassUp functions.

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

Design reactions are divided. Some reviewers like the curved boombox look, colors, and lighting, while others criticize the plasticky feel or large, unsubtle footprint.

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

Detail retrieval is acceptable for a party speaker but not a major strength. Reviewers repeatedly note that detail, definition, or nuance falls behind the bass impact and loud outdoor presentation.

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

High-volume distortion performance is mostly strong. Several reviews say it stays clear or avoids distortion at loud levels, though one noted radiator buzzing or definition loss on some intense bass tracks.

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

Durability evidence is favorable for ordinary outdoor abuse, accidental knocks, and water exposure. Reviewers mention rugged construction, protection against tumbles, and surviving a minor household impact without visible damage.

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

Dust resistance is a clear weakness. Multiple reviews state that the speaker lacks an official dustproof rating, making it less ideal for sandy or dusty use despite strong water resistance.

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

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

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

EQ customization is one of the strongest software features. Reviewers describe nine-band or full-band EQ controls, presets, and the ability to tailor sound for indoor, outdoor, or personal listening preferences.

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

Everyday usability is strong when used as a portable party speaker. Reviewers cite easy setup, useful controls, water resistance, carry hardware, and power-bank functionality, with size and battery caveats.

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

Float capability is strongly confirmed. Multiple reviewers tested or stated that the Boom 2 Plus floats, making it particularly suitable for pools, boats, and wet outdoor settings.

Frequency balance is intentionally bass-forward. Reviewers often praise full, clear, or dynamic sound, but also note that mids, vocals, or detail can be recessed when BassUp or high volume emphasizes the low end.

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

Google-related evidence is limited to Google Fast Pair support and some voice-assistant references. The product appears to support quick Android pairing, but reviews do not show broader Google ecosystem integration.

Google Fast Pair support is explicitly mentioned.

Handle and strap quality is consistently positive. Reviewers praise the molded or grippy handle, included shoulder strap, and general carry convenience for an eight-pound-plus speaker.

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

Inter-speaker connectivity is well documented through PartyCast 2.0 and TWS references. Most reviews discuss the feature as supported; a few did not test it, while one YouTube review reports reliable multi-speaker use.

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

Latency evidence is limited but favorable. Reviewers mention low or acceptable Bluetooth lag, including use for movie audio behind a tablet or laptop.

LED lighting is widely discussed and generally considered fun, customizable, and party-friendly. A few reviewers call it gimmicky or poorly synced, so the score varies by review.

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

Lighting effects are a visible differentiator, with multiple presets, custom colors, and beat-sync behavior. Reception is positive overall, though some reviewers view the feature as decorative rather than essential.

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

Maximum volume is a major strength. Across written and video reviews, the Boom 2 Plus is described as very loud, outdoor-capable, and able to fill rooms or parties with strong bass-backed output.

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

Low-volume evidence is limited but positive where mentioned. Reviewers note that bass can still be felt at lower levels and that the speaker can work at reasonable indoor volumes, though its main purpose remains loud party playback.

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

Microphone evidence is contradictory. Some reviews say there is no microphone or no call support, while SoundGuys reports a built-in microphone with decent clarity, so the overall support is mixed.

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

Multi-speaker pairing is repeatedly supported through PartyCast 2.0 and TWS references. The feature promises large Soundcore speaker groups or stereo pairing, but many reviews describe it rather than fully testing reliability.

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

Multipoint evidence is mixed. PCMag and some video reviews report pairing with two devices, while Sound & Vision says it cannot pair more than one phone.

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

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

On-device controls are strong. Reviewers highlight physical buttons for playback, volume, Bluetooth, lights, PartyCast, and BassUp, reducing the need to reach for the app for common functions.

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

Power-bank functionality is consistently praised. Reviews mention USB-C device charging, phone top-ups, and 30W power delivery as useful for long outdoor sessions.

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

Price and value are generally positive, especially around $249 or sale pricing. Some reviewers note stiff competition, but many describe it as strong value for loudness, bass, water resistance, and features.

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

Privacy and data evidence is minimal but favorable where discussed: one review praises the app for not requiring an email account. The reviews do not provide deeper privacy analysis.

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

Setup is consistently described as simple and fast, with easy Bluetooth pairing and app onboarding. Reviewers generally characterize first use as intuitive.

Basic pairing is described as quick and uncomplicated.

Smart assistant integration appears weak or absent in the available reviews. The clearest evidence says there is no microphone for calls or voice assistant support.

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.

Speakerphone evidence is inconsistent. Some reviewers say the Boom 2 Plus lacks speakerphone or microphone support, while one reports usable call clarity through a built-in microphone.

Status indication is only adequate. Reviewers note app battery readouts and a low-battery red light, but one specifically criticizes the lack of a physical battery-level indicator.

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

Stereo imaging evidence is modest. Reviewers note stereo output, soundstage size, and TWS pairing potential, but the product is still reviewed mainly as a loud boombox rather than an imaging-focused speaker.

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

Low-end hardware is a strength. Reviewers cite dual woofers, built-in subwoofers, passive radiators, and deep 40Hz bass, all reinforcing its bass-first party role.

USB-C charging is consistently supported, with USB-C-to-USB-C cables, fast charging, and a port that can also power external devices.

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

Value-for-money evidence is positive overall, especially when reviewers compare loudness and feature count against more expensive speakers. A few caution that rivals may offer better protection or bass for slightly more money.

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

Voice-assistant responsiveness is not a strength because the clearest direct evidence says there is no voice-assistant microphone support. No review provides positive voice-assistant performance evidence for the Boom 2 Plus.

Voice clarity is generally acceptable but not the product’s focus. Reviewers mention clear vocals in some tracks and podcasts, while others report muffled vocals or reduced midrange detail when bass dominates.

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

Water resistance is one of the best-supported strengths. Reviews repeatedly cite IPX7 protection, successful splashing, rinsing, submersion, pool use, and wet outdoor operation.

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

Weight convenience is mixed. Reviewers appreciate the handle and strap and often call it manageable for its output, but its size and weight make it less suitable for backpacks, planes, or long walks.

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

Wired input support is clearly documented through the 3.5mm auxiliary input. Reviewers mention aux playback for parties, DJ/projector use, and wired listening.

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