Compare SonoFlow SE HQ31 Wireless Headphones vs Bose QuietComfort Ultra Bluetooth Headphones (2nd Gen)

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.

Noise cancelation is consistently described as top-tier and often best-in-class, with Gen 2 seen as a small refinement (more precise, fewer quirks); some outlets still give Sony a slight edge in ultimate silence. Most reviews highlight easy ANC control through modes or a slider (often 1–10) and note Gen 2 can fully disable ANC, which improves flexibility and battery options.

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

Android support is repeatedly described as strong, with easy pairing and the best codec features (aptX family) available on compatible Snapdragon phones.

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 companion app is generally stable and straightforward for modes, ANC, immersive audio, and device management, but many reviewers describe it as basic compared with feature-rich competitors.

Reviews that discuss codecs call out aptX Adaptive and related options (including lossless/low-latency variants on compatible Snapdragon devices) as a meaningful plus for Android users.

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.

USB-C wired audio is noted to reduce Bluetooth latency by tens of milliseconds, which can improve lip-sync for video compared with wireless use.

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 widely praised as deeper, punchier, and more controlled than the prior model, though a couple reviewers still describe it as warm or occasionally one-note depending on genre and settings.

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 reported around 27–30 hours with ANC on, which is competitive but not class-leading; immersive/spatial modes reduce runtime, and some sources note longer life with ANC off.

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

Bluetooth performance is often described as quick to connect and stable in daily use, but a minority report occasional connection quirks or issues.

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 generally seen as durable enough for daily travel, but the heavy use of plastic and occasional rattly feel reduce the perceived premium value at this price.

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.

Physical buttons are serviceable but frequently criticized for doing too many functions (pairing/power, multi-press combos) and offering limited customization.

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

Several reviewers mention the 2.5mm analog input as less common than 3.5mm, but the included cable and USB-C option make it easy to stay connected when needed.

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

The included case is widely appreciated for being sturdy and compact, though some reviewers find the folding orientation awkward or wish the case design were quicker to open/close.

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 typically described as convenient, with quick-charge figures around 15 minutes for a few hours of playback and full charge around a few hours; USB-C also enables charging while listening.

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 gentle and fatigue-free, but a few reviewers find the fit on the snug side (great for seal) or potentially too loose for smaller heads during movement.

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

Codec support is described as modern and well-rounded for 2025-era ANC headphones, with standard codecs plus aptX Adaptive family and multiple wired options; performance depends on your source device 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 core strength: many reviewers call it class-leading for long sessions thanks to light weight, plush pads, and an easy seal, with only occasional notes about heat buildup or fit preferences.

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 largely unchanged from the previous generation, with updated glossy accents and more color options; reactions range from stylishly understated to a bit boring or too fingerprint-prone.

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.

At least one reviewer notes there is no dedicated low-latency wireless dongle, limiting plug-and-play latency solutions for gaming compared with some rivals.

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

Earpads are typically described as soft, deep, and comfortable, though some users note ears can touch the inner padding or that the surface may not feel ultra-premium to the touch.

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

The yoke/rotation design allows the cups to lay flat, but at least one review notes the rotation range is limited in one direction.

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 control is repeatedly called out as limited (a simple 3-band slider), good for small tweaks but not ideal for listeners who want granular tuning.

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.

Tonality can be shaped into a more balanced response with CustomTune and light EQ, but out of the box many characterize it as a V-shaped or slightly dark consumer tuning rather than strictly neutral.

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.

Where mentioned, the metal headband/hinge structure is viewed as reassuring, even though much of the exterior uses plastic to save weight.

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

Accessories are typically described as solid for the category, with a sturdy case plus USB-C and analog cables included for flexible connections.

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 rated good-to-excellent, with most reviewers finding layering and placement strong; a few note busy mixes can still blur slightly.

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.

Noise reduction on calls is usually effective, keeping background sounds lower while preserving speech, though some tests still let intermittent noise bleed through or add a slightly processed character.

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 good for a premium ANC headphone, with most reviewers saying voices stay intelligible in noisy places; a few describe it as merely fine, compressed, or not exceptional.

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 generally clear with solid vocal presence, but some reviews note slightly recessed or less biting mids (especially for guitars/rock) compared with top competitors.

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

Cross-platform use is a common strength, with reviewers noting smooth switching between phones and computers across iOS and Android ecosystems.

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

Multipoint is widely praised as seamless for two devices with smooth switching; a couple edge cases (e.g., juggling TV/phone or certain setups) can be finicky.

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 benefits from a good seal and deep cups, but a few reviewers note the foam is not the thickest; overall, it helps the ANC work even better on commutes.

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

Portability is strong for a flagship ANC headphone: the frame folds and articulates well, keeping the carry footprint compact for travel.

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

Preset EQ or mode profiles exist and can help (e.g., bass-reducing or treble-boosting options), but many reviewers find the presets and overall EQ ecosystem underwhelming.

Replaceable earpads are highlighted as a practical perk for long-term ownership, cleaning, and swapping for third-party pad options.

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

Sensors and automation (on-head detection, auto pause, low-power modes) are often praised for making the headphones feel effortless day to day.

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

Glossy accents look more premium to some, but multiple reviewers mention they pick up fingerprints and dust more easily than matte finishes.

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 is generally described as simple, with fast pairing and reliable auto-connect behaviors that reduce daily friction.

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, the sound is described as enjoyable and travel-friendly, with a consumer-leaning tuning and strong bass; several reviewers say it improves on Gen 1, but a few still find it only fine or a bit dark versus audiophile-leaning rivals. Wired playback (especially over USB-C) is frequently described as clearer or more detailed than Bluetooth, with the bonus of charging-while-listening; analog wired is also supported for older sources.

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 repeatedly called wide and open for a closed-back ANC headphone, helping music and movies feel less 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.

Immersive/spatial features (including cinema mode) get mixed reactions: some love cinema for clearer dialogue and a bigger movie feel, while others dislike the processing and prefer 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.

Fit stability is good for desk work, commuting, and light movement, but several reviewers caution it is not ideal for more dynamic workouts due to the lack of an IP rating and comfort-first clamping.

The touch volume control is divisive: some find it responsive and sleek, while others call it imprecise or too easy to trigger large volume changes, especially without tactile feedback.

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 commonly rated among the best and natural-sounding, though several reviewers mention a faint hiss/white noise or slightly reduced openness versus the very best implementations.

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 typically smooth and cleaner than Gen 1, avoiding harshness; however, multiple reviewers wish for more sparkle or micro-detail and often add treble via EQ.

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 a key Gen 2 upgrade, enabling digital audio input (often described as lossless/hi-res) in addition to charging, and allowing simultaneous charge-and-listen use cases.

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

Voice assistant access is supported via shortcuts or touch-and-hold actions in the app, making it easy to trigger assistants without pulling out your phone.

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 generally ample, and at least one reviewer reports slightly higher output when using USB-C wired audio.

Multiple reviews emphasize there is no official water or sweat rating, making these a poor choice for rain, heavy workouts, or sweaty gym sessions.

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 repeatedly highlighted as a major comfort advantage versus heavier rivals, making it easier to wear for travel and workdays.
