Compare SonoFlow SE HQ31 Wireless Headphones vs Soundcore Space 2

A 3.5mm analog jack/cable is repeatedly confirmed for wired listening.

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 one of the most supported strengths, especially against low-frequency travel noise, though it does not match top flagships.

Advanced features are unusually broad for the price, including AI assistant, translation, Nap Mode, Soundscape, and white noise.

The look is clean, subtle, and discreet, with black available for the most low-profile appearance.

ANC background noise is much lower for rumble and crowd noise, but voices, high tones, and some hiss can remain.

ANC sound impact is positive in the direct evidence: one review says it does not hurt the sound.

One review specifically says ANC does not adversely affect the headphones' sound, which is a positive sign.

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

Android users get the best experience through Fast Pair and LDAC support, while iPhone users lose LDAC.

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 Soundcore app is repeatedly described as feature-rich, useful, and central to ANC, EQ, HearID, and extras.

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.

Wear detection and auto-play/pause are repeatedly listed as useful quality-of-life features.

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 repeatedly described as punchy, full, or impactful without usually becoming muddy, though a few reviewers found it bass-forward.

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 one of the strongest consensus positives, with most reviews citing around 50 hours ANC and 70 hours without ANC.

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

Bluetooth performance is modern and generally well supported, centered on Bluetooth 6.1 and app-connected wireless use.

Bluetooth 6.1 is repeatedly cited, giving the Space 2 a very current wireless spec.

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 mostly good for the price, though not all reviewers find it premium or rugged enough.

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.

Hi-res playback is supported through LDAC and high-res wired/wireless certification, but USB-C audio is not supported.

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.

Physical buttons are praised as straightforward, tactile, and easier than uncertain touch gestures.

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

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

The included carry pouch is the recurring weak point; reviewers often wanted a hard-shell case.

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 highly rated because multiple reviews cite five minutes of charging for roughly four hours of playback.

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 mostly comfortable and stable, though one review found it strong and heat-building.

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

Codec support is strong for the class, with AAC/SBC plus LDAC and, in one review, LC3 support.

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 a standout theme across reviews, with many testers wearing them for hours or workdays.

Connectivity is broad for the category, combining Bluetooth, multipoint, LDAC, Fast Pair, and 3.5mm wired listening.

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 feedback is positive but understated: clean, familiar, good-looking, and available in multiple colors.

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.

A detachable 3.5mm cable gives the headphones a useful wired fallback when Bluetooth or battery is not ideal.

Long-term durability remains uncertain in one review, especially for repeated travel and bag use.

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 memory-foam ear pads are repeatedly described as plush, cushy, deep, or soft.

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

One review notes the earcups swivel flat, supporting desk or travel storage.

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 strong, with custom eight-band EQ, HearID, and meaningful tuning tools repeatedly mentioned.

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.

Frequency accuracy is not described as reference-grade; one review says fine detail and precision are not the last word.

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

Headband padding is consistently described as cushioned, soft, or evenly distributing weight.

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

Hinge comments are positive where mentioned, with solid feel or built-to-last impressions.

Immersive audio is only modest: 3D mode can add depth but often sounds thinner, artificial, or less useful than stereo.

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

Included accessories typically cover the basics: soft pouch, USB-C charging cable, 3.5mm audio cable, and user guide.

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 is a consistent strength in music-focused reviews, with reviewers able to pick apart or place instruments.

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.

Integrated microphone support is clear through repeated mentions of a three-mic array for calls.

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

LDAC is a major recurring feature, praised for high-res Android listening but limited or absent on iPhone.

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.

The three-mic or AI noise-reduction system is repeatedly mentioned as helping calls and background suppression.

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 usable to solid, with better performance in typical or quieter environments than in wind or loud settings.

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 performance is mixed: several reviewers heard clear or forward vocals, while others found vocals recessed or partly masked by bass.

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

The headphones work across iOS, Android, Bluetooth, and analog wired use, though high-res LDAC favors Android.

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

Multipoint is widely mentioned as present and useful, including dual-device connection support, though one review notes no Auracast.

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 isolation is helped by the sealed earcups and clamping/fit, adding to the ANC performance.

Offline/onboard playback evidence is limited to built-in Nap Mode soundscapes stored on the headphones.

Overall recommendations are strongly positive, especially for buyers seeking value, comfort, ANC, battery, and features.

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

Foldability is a travel advantage, though some reviewers note it is not the most compact design.

Premium feel is better than expected for the price in several hands-on comments, though it is not universally premium.

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

Preset EQs are plentiful and useful, with Soundcore Signature, Acoustic, Bass Booster, and other modes mentioned.

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

Sensor evidence centers on the wear/proximity sensor used for smart wearing detection.

Smart listening features are unusually broad, including HearID, Safe Volume, Soundscape/Nap Mode, and relaxation audio.

Smart Pause is generally reported as seamless or useful once wear detection is enabled or used.

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

Smudge resistance is a minor weakness, especially for the black finish, which attracts marks or fingerprints.

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 described as straightforward or easy to navigate, especially after pairing.

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.

Reviewers broadly describe the Space 2 as strong for the price, with enjoyable, detailed sound and only minor tuning caveats.

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.

Reviewers who discussed staging found it wide or spacious for closed-back budget over-ears.

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/3D audio is present but mixed, with several reviewers preferring normal stereo for music.

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

Stability is supported both by stable pairing comments and by a secure on-head fit.

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 works for awareness but receives mixed notes about hiss, artificial tone, or amplified ambient noise.

Travel friendliness is supported by long battery life, folding design, ANC, quick charge, and relaxation features.

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 described as clean, crisp, and non-fatiguing rather than top-tier sharp.

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 used for charging and quick charging, but one review notes it does not carry USB-C audio.

Value is one of the strongest conclusions, with reviewers repeatedly saying the features and performance exceed the price.

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

Voice assistant support is available through customizable button actions, including phone assistant or Anka.

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.

One reviewer noted volume needed to be raised in noisy transit, so volume output is adequate but not immune to ANC limits.

Water resistance is a clear limitation because reviewers note no IP rating or no water-resistance claims.

Automatic pause when removed is one of the most consistently mentioned smart features.

Wear detection performance is generally reliable and quick in reviews that evaluated it.

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

Low weight is consistently praised, with reviewers citing roughly 261–265g and easy long-session wear.

Wind handling is a weakness: a reviewer says the headphones lack wind reduction and struggle in blustery conditions.
