Compare SonoFlow SE HQ31 Wireless Headphones vs Sonos Ace Wireless Over-Ear Headphones

ANC is a real strength for the price. Most reviewers said it handles low-frequency noise very well and beats expectations for a budget model, even if it does not match Bose or Sony flagships. Mode control is flexible. Reviews repeatedly mention easy switching between ANC, transparency, and normal modes through the app or hardware button.

ANC is widely rated strong for travel and commuting, and multiple reviewers say firmware updates pushed it closer to class leaders. A minority still place Bose and Sony slightly ahead, but few call the Ace weak at cancelling steady noise. Most reviews describe limited user control over ANC intensity: typically on, off, or Aware mode, with some adaptive behavior added over time. If you want multiple manual levels like Bose offers, this is a common disappointment.

Android support looks strong. Reviewers specifically cited the Android app experience and LDAC activation on Android devices as working as expected.

Android compatibility is generally solid, and Android users get the biggest upside from aptX Lossless and broader codec support. Some Sonos home-theater features started iOS-first, but later updates expanded support according to reviewers.

The app is feature-rich but divisive. Several reviewers liked the EQ, firmware, and mode controls, while others complained about crashes, lag, ads, and rough translation.

The Sonos app is needed for setup, updates, EQ, and home-theater features, and opinions are mixed. Some like the simplicity and redesign, while others report pairing hiccups, limited options, or updates that feel slower than they should.

aptX support, including aptX Lossless on compatible Snapdragon Sound devices, is frequently cited as a meaningful advantage over some rivals. Android users benefit most from this capability.

Low-latency performance is generally solid. Reviewers who tested gaming or video playback reported little to no obvious lag, though one review found the mode made little audible difference.

Audio-video sync is usually described as low-latency for movies and TV, especially when features are working properly. A couple of reviews report occasional lip-sync hiccups during TV Audio Swap that were resolved by reconnecting or pausing playback.

Bass is usually described as punchy, warm, and enjoyable. It has enough emphasis for pop, hip-hop, and EDM, but it can also sound a bit overboosted depending on tuning and preset.

Bass is commonly described as full and controlled, helping the Ace feel rich and premium. Some reviewers want more rumble and impact for movies, while others feel the default tuning can lean a bit bass-forward compared with neutral targets.

Battery life is one of the biggest reasons to buy these headphones. Nearly every review praised the 60 to 90 hour endurance as exceptional for the class.

Battery life is generally reported around the advertised 30 hours with ANC, and several reviewers call it a strong point. A few wish it were longer, but most agree it is competitive in the premium class.

Bluetooth performance is consistently reliable. Reviews noted fast pairing, stable connections, and good range with few complaints about dropouts.

Bluetooth stability is mostly reported as solid with reliable day-to-day connections. Some reviews mention brief dropouts or stutters, especially around early firmware or when using TV Audio Swap.

Build quality lands above average for the price but not premium. Most reviewers found the plastic shell solid enough, while a few called the frame or hinges wobbly or plainly budget-grade.

Build quality is typically described as premium and well-finished, with sturdy materials and a polished look. A few reviews mention early quirks or software-related rough edges, but physical construction is rarely the main complaint.

Hi-res playback support is a plus here. LDAC and high-res audio claims were repeatedly highlighted, though reviewers focused more on wireless playback than any dedicated DAC behavior.

Physical controls work, but they are not especially intuitive. The biggest complaint is the reversed track-skip behavior on the volume rocker, even though button feel itself is usually decent.

The included cable is a weak point. Reviews that mentioned it called the USB cable very short and more utilitarian than convenient.

Cable quality is mostly fine, but at least one review explicitly complains that the included USB-C cable is too short for comfortable desktop or couch use.

Accessory protection is minimal. Multiple reviews specifically noted that no carrying case or pouch is included.

The included case is usually praised as protective and slim, and it looks premium on the outside. A few reviewers dislike the material feel, zipper behavior, or the finicky fit when packing the headphones away.

Charging performance is very good. USB-C, fast-charge support, and short top-ups that return hours of listening time were all praised.

USB-C charging and fast-charge behavior are widely praised, with multiple reviews citing short top-ups that deliver hours of use. Full charge times and convenience compare well against Lightning-based rivals.

Clamp force is one of the main comfort complaints. Some users liked the secure fit, but several found the pressure too tight for longer sessions.

Codec support is excellent for the price. LDAC is widely mentioned, and one review also listed SBC and AAC alongside it.

Codec support is a key talking point: AAC for iPhone, aptX and aptX Lossless via Snapdragon Sound for compatible Android, plus wired USB-C audio. One review notes the lack of LDAC, so codec completeness depends on what you expect.

Long-session comfort is mixed. Some reviewers wore them for hours without issue, while others reported fatigue from clamp, heat buildup, or overall heft.

Comfort is one of the strongest consensus positives: many reviewers say the Ace disappears on the head for long sessions. Some note the cups can feel tight for larger ears or get warm, but comfort is still often ranked top tier.

The design is simple and modern but not especially luxurious. Color options and clean styling help, though several reviews still described the look as plainly budget-oriented.

Design is broadly seen as sleek, minimalist, and premium, with physical controls that many find more reliable than touch pads. Cosmetic preferences vary, but the Ace generally scores high on aesthetics.

Wired use adds some flexibility, but convenience is limited. Reviews mention USB-C wired mode rather than a normal 3.5mm setup, and the cable situation is not ideal.

Padding quality is mostly a plus. Reviewers frequently described the ear pads as soft and pleasant, even when other fit-related comfort issues remained.

The earcups rotate or lie flat, which helps both neck comfort and storage. Reviewers who mentioned it saw this as a useful portability feature.

EQ control is a strong feature. The app offers multiple presets and, in several reviews, a custom EQ that makes it easier to tune the sound to taste.

EQ customization is frequently described as basic, often limited to simple bass and treble adjustments. It helps fine-tune warmth but is less flexible than multi-band EQs offered by several competitors.

Frequency balance is not especially accurate. Reviewers often heard boosted bass, dipped mids, or sharp or rolled-off treble, although a few still found the overall tuning enjoyable.

Headband adjustment appears adequate. Reviews that mentioned sizing said the extenders allow a workable fit for larger heads.

Hinge confidence is limited. The only detailed hinge-related comment described the cups and hinge area as too wobbly.

The box contents are basic. Most reviews mention only the headphones, a short USB cable, and documentation, with no premium extras.

Included accessories, especially the hard case and cables or adapters, are generally viewed as generous for the category. A couple of reviewers still wish for longer cables or more flexibility, but the bundle is mostly well received.

Instrument separation is decent rather than standout. One detailed review noted that the headphones can organize detail well enough to keep recordings coherent and not overly congested.

Instrument separation and imaging are often highlighted as a strength, with good layering and placement for a wireless ANC headphone. Even mixed reviews tend to credit the Ace for clarity in complex mixes.

The built-in mic is usable and often better than expected for the price. Call performance ranges from merely okay in quieter spaces to impressively clear in stronger reviews.

LDAC support is one of the model’s biggest spec advantages. It is repeatedly cited as a rare feature at this price.

Maximum loudness is not a strength. The few reviews that addressed it described limited headroom or some distortion concerns rather than effortless clarity at high volume.

Noise reduction for calls is mixed but often effective. Some reviewers praised the dual-mic ENC for cutting traffic and wind, while others said voices could still sound distant in noise.

Microphone noise reduction is often described as effective at suppressing background noise, though not always the best in class for wind or the noisiest streets. Overall, most reviewers consider it reliable for calls.

Call quality is better than expected overall. The strongest reviews praised clear, loud voice pickup, but a few others found performance only acceptable in quiet environments.

Call quality is generally rated good to very good, with clear speech in typical environments. A few reviews call it average or slightly muffled, and one notes updates aimed at improving the microphones over time.

Midrange clarity is uneven. Vocals can sound forward and engaging, yet several reviewers also heard recessed or coarse mids depending on tuning and preset.

Midrange is typically clear and pleasant for vocals, though a few reviews note mild recession depending on the track and default tuning. With light EQ, several reviewers say vocals regain balance easily.

Cross-platform use appears strong. One review specifically praised smooth switching between iOS, macOS, and Android devices.

Multi-platform compatibility is generally strong for phones and computers, and the Ace can also integrate with compatible Sonos soundbars. The biggest platform caveats are codec differences (Android vs iOS) and which devices support specific Sonos features.

Multipoint works well when used. Reviewers who tested dual-device pairing generally described switching as fast and seamless.

Multipoint is commonly praised for convenience and generally works well for hopping between phone and laptop. One review reports clunky or inconsistent behavior, so it is not universally flawless.

Passive isolation is respectable but not perfect. The seal is good enough for everyday use, though fit and cup size can limit isolation for some listeners.

Portability is a plus. Several reviews highlighted folding or flat-laying earcups that make the headphones easier to carry around.

The Ace folds flat but does not fold into a compact bundle, so portability depends heavily on bag space. The case is often described as slim, but still fairly wide.

The preset EQs are mostly useful. Reviewers liked having many options, though some felt only a subset of the presets were genuinely worthwhile.

Replaceable, often magnetically attached earpads are praised as a practical, premium touch for long-term ownership. Reviewers generally like the ease of removing and reattaching pads.

Sensor extras are very limited. One review explicitly noted the lack of wear detection or similar smart convenience features.

Sidetone is highlighted as a useful calling feature when available, feeding some of your own voice back naturally so you do not over-project. Not every review treats it as essential, but those who mention it tend to be positive.

The matte finish appears to resist fingerprints well. Smudge resistance was only mentioned once, but it was a positive note.

Setup and software experience depend heavily on the reviewer. Some found pairing and app navigation easy, while others ran into buggy behavior and needed restarts.

Setup and software are mixed: many find pairing straightforward, while others report app detection issues, feature rollouts that arrive later, or firmware updates that take patience. Updates have also meaningfully improved ANC and home-theater features over time.

Overall sound quality is good for the money, not for purists. Most reviewers found the tuning enjoyable and competitive at the price, but several also wanted more refinement and realism.

Sound quality is generally praised as warm, smooth, detailed, and spacious, making it easy to enjoy for long sessions. The recurring critique is that it is not always as punchy, dynamic, or incisive as the very best at this price, and the limited EQ means you cannot fully reshape the signature.

Soundstage is better than expected for a cheap ANC headphone, especially with spatial audio on. Still, some reviewers found it only average or even narrow.

Soundstage is frequently called spacious for a closed-back, and it becomes more enveloping with spatial audio enabled. Reviews describing movie playback often emphasize the wide, out-of-head presentation.

Spatial audio is a pleasant bonus rather than a headline feature. Most reviews found it adds width or fullness, but it is not treated as a true premium immersive implementation.

Spatial audio and Dolby Atmos support are widely considered a headline strength, especially for movies and TV, with head tracking adding immersion for many listeners. A minority see it as a gimmick for music, but overall sentiment is strongly positive.

Fit stability is acceptable but not perfect. A secure clamp helps for normal use, though one review noted slipping during gym bench work.

Stability on the head is usually good for everyday use, but one review notes slipping when sweaty. If you plan on workouts, fit stability and heat build-up can be a consideration.

Transparency mode is a standout feature. Many reviewers said it sounds unusually natural and useful for conversations, outdoor awareness, and quick check-ins with the environment.

Transparency or Aware mode is consistently described as natural and easy for conversations, often compared favorably with top competitors. A few reviewers still prefer Apple or Bose, but overall sentiment is very positive.

Treble performance is mixed. Some reviews heard decent clarity, while others called the top end rolled off, sharp, or less refined than competitors.

Treble is usually characterized as clean and non-fatiguing, avoiding harshness. A few listeners want more sparkle and air, especially compared with brighter, more energetic rivals.

USB-C support is a clear convenience win. It is consistently mentioned for charging, and several reviews also tie it to wired operation.

USB-C is consistently appreciated for both charging and wired audio, and many reviews call it a clear win over older Lightning implementations. It also supports practical desktop and travel use cases.

Voice assistant support is solid where tested. Siri and Google Assistant were reported to respond accurately through the hardware controls.

Volume output is merely adequate. Reviews that mentioned loudness either wanted more headroom or said the headphones can get reasonably loud, but it is not a standout strength.

Most reviewers find music playback loud enough, but TV Audio Swap volume is repeatedly described as quieter than music. At least one reviewer also reports a low-volume floor or coarse steps that make quiet listening harder.

Multiple reviews point out there is no official IP rating, making the Ace a weaker pick for workouts, heavy sweat, or rain exposure. Some still use it casually at the gym, but it is not positioned as a sport headphone.

Weight comfort is mixed. Some reviewers found them light enough for long wear, while others noticed the mass quickly and preferred lighter alternatives.

Weight comfort is routinely praised, especially compared with heavier metal competitors. The lighter feel is a major contributor to long-session wearability.
