Compare SonoFlow SE HQ31 Wireless Headphones vs DALI IO-12 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 broadly described as effective for reducing low rumbles and general ambient noise, but it is not considered class-leading compared with flagship Bose, Sony, or Apple models; some mention susceptibility to wind noise. Noise cancellation adjustability is limited to onboard mode switching in most coverage, with some sources noting multiple ANC modes, but no fine tuning via app.

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

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.

Multiple sources confirm there is no companion app for the IO-12.

Multiple reviews explicitly cite aptX options, including higher-tier variants such as aptX HD and aptX Adaptive, as part of the IO-12 wireless feature set.

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.

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 typically described as tight and controlled in Hi-Fi mode with convincing weight, while Bass mode adds slam and warmth without turning into a boomy mess, though it can trade away some treble presence.

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 commonly cited around 35 hours, with at least one real-world report closer to 30 hours; overall it is respectable but not exceptional relative to cheaper competitors.

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

Bluetooth connectivity is commonly reported as stable, with fast pairing and few to no dropouts even in busy environments.

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 repeatedly described as ultra-premium, with strong materials and a luxury feel that holds up to travel use when handled with care.

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.

Buttons are often praised for responsiveness and tactile feedback, but a few reviewers mention accidental activation, especially when adjusting volume or leaning against a seat while traveling.

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

Cable quality feedback is mixed: some appreciate the included cables and finish, while at least one reviewer calls the cable frustrating to use and prefers the shorter option.

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

The carry case is typically praised as premium and protective, with good structure and compartments, but it adds bulk and can be impractical for compact packing.

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

Charging is described as taking roughly 1.5 to 2 hours from flat with no fast-charge boost mentioned, and one reviewer notes behavior consistent with limiting charge to protect long-term battery health.

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.

Clamping force is usually described as secure but comfortable, ranging from light to moderately firm depending on the reviewer, without feeling unstable.

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

Codec support is positioned as strong for a premium wireless headphone, with repeated mentions of AAC and aptX-family options that help preserve detail over Bluetooth.

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

Long-session comfort is one of the most consistently praised aspects, with roomy earcups and plush pads that avoid pressure points for many listeners.

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 widely described as premium and distinctive, but the dark chocolate color can divide opinion, and the large earcups create a bold, bulky look on some heads.

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.

Earcup and pad materials are frequently described as plush, premium leather with generous space for larger ears, contributing to both comfort and isolation.

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

Earcups are commonly described as able to swivel or lay flat, aiding seal and travel storage even though the overall design does not fold compactly.

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.

Without an app, EQ customization is not available beyond onboard preset modes, which limits personalization compared with mainstream flagship wireless headphones.

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.

Hi-Fi mode is commonly described as balanced and relatively uncolored, while Bass mode shifts the tonality warmer and can slightly reduce upper-mid and treble prominence.

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

Headband adjustment is described as smooth and secure, holding its position well once set.

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 are generally considered generous, with multiple cables and adapters plus a premium case, though some note the absence of a USB-C to USB-C cable.

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 consistently praised, with precise placement and clear spacing between layers even 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.

Reviews that discuss loud listening report strong composure and minimal distortion at higher volumes, encouraging careful use because it stays clean as you turn it up.

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.

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.

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 clarity is repeatedly highlighted as a standout strength, with clean layering and realistic vocal and instrument textures that feel unusually hi-fi for Bluetooth.

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

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

Multipoint is noted as supported and convenient for staying connected to two devices, though it is not heavily stress-tested across all sources.

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.

Passive noise isolation is described as strong thanks to large, well-sealing earcups and design details aimed at closing gaps around the ear, providing a solid foundation before ANC is even enabled.

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

Portability is a recurring compromise: the headphones are large, do not fold down compactly, and several reviewers mention the case is too big for many backpacks.

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

Preset sound modes are generally seen as well-judged: Hi-Fi is the reference setting for balance and clarity, while Bass mode adds punch and warmth, sometimes with a tradeoff in treble and mid presence.

Replaceable earpads are explicitly mentioned as a welcome premium touch, with pads that can be removed for cleaning or replacement.

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

Some coverage notes the absence of wear sensors and similar smart conveniences found on mainstream flagships, reinforcing the IO-12 focus on audio and simplicity over automation.

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.

Day-to-day operation is described as straightforward because settings are handled on the headphones, but the lack of an app also means limited customization and some sources note manual firmware updating.

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.

Across reviews, sound quality is the headline: a speaker-like, highly resolving presentation that many call among the best in wireless closed-backs, with strong imaging and refinement. Wired sound is often described as equal or better in resolution than wireless, with USB-C and 3.5 mm options; passive use is supported, and some recommend listening powered on to benefit from onboard DSP.

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.

Most reviews describe an unusually open, spacious soundstage for a closed-back wireless headphone, with strong width and credible depth; one reviewer notes it is not stadium-wide but avoids feeling claustrophobic.

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.

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

Fit stability is generally described as secure with a good seal, but the sizing and overall footprint may feel better suited to average-to-larger heads than very small ones.

Control surfaces are generally responsive; some coverage mentions touch-style control areas, but overall interaction is described as clicky and deliberate rather than finicky.

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 mode is generally described as clear and practical for awareness, without strong criticism, though fewer reviews go deep on its nuance.

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 generally airy, detailed, and smooth, with occasional notes that it can approach brightness on certain recordings; Bass mode can tame the top end if needed.

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 highlighted as both a charging and playback option, with multiple sources noting USB audio support up to 24-bit and 96kHz.

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

Voice assistant support is described as available via a press or long-press action, and some sources also mention voice prompts for battery status.

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.

Volume output is commonly described as having plenty of headroom, with enough drive to get loud without feeling strained.

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

Weight is noted as present but generally not burdensome once worn, though some acknowledge the overall heft and size compared to mainstream travel headphones.
