Compare SonoFlow SE HQ31 Wireless Headphones vs Beyerdynamic Aventho 300 Wireless 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 performance ranges from decent to underwhelming for the price; it tends to handle low-frequency rumble better than mid and high-frequency noise, and trails class leaders. ANC settings are flexible, with multiple strength levels (and an adaptive mode) available via the app and on-headphone controls.

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

Android use is generally smooth, with modern codecs and stable pairing frequently mentioned as benefits for Android users.

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 typically seen as clean and easy to navigate, though not feature-rich compared with the very best ecosystems.

aptX support (including Lossless/Adaptive) is repeatedly cited as a key advantage, especially for Android and Snapdragon Sound 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.

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 a defining trait: commonly thick and boosted with good extension, but several reviewers call it boomy or overdone until EQ is applied.

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 a headline strength: many cite around 50 hours with ANC on, and some tests report substantially higher real-world endurance.

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

Bluetooth stability is a strong point in most reviews, with few dropouts reported and Bluetooth 5.4 frequently highlighted.

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 consistently highlighted, with metal components and a sturdy, low-creak feel that compares favorably to many all-plastic competitors.

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 get mixed feedback: some find them small, mushy, or hard to distinguish by feel, while others report they work fine once learned.

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

Accessories include both USB-C and 3.5mm cables (plus an adapter in several reviews) and are generally viewed as solid and practical.

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

The carry case is frequently praised as premium and protective, and several reviewers like that a soft pouch or dust bag is also included.

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

Charging over USB-C is straightforward, with fast-charge claims around 10 minutes for roughly 5 hours and full-charge times around two hours.

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 often skews tight, which helps stability and seal but can become fatiguing for larger heads.

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 standout, commonly noted for including AAC plus higher-end options like aptX Lossless, aptX Adaptive, and LE Audio.

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 divisive: some find the fit pleasant, while others report discomfort after an hour or two due to clamp, heat, or ear clearance.

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 generally seen as sleek and premium-looking, leaning understated rather than flashy; finish impressions vary from fingerprint-resistant to smudge-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.

Detachable wired options add flexibility for travel, low-latency use, and compatibility with sources that cannot use Bluetooth.

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

Pads are described as plush by some and stiff or shallow by others; deeper cups help, but heat build-up and ear contact show up in multiple accounts.

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

Cup swivel and articulation are well regarded, allowing the headphones to lay flatter and fit a range of head shapes; a few note minor rocking from pad shape.

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 options center on a 5-band equalizer and presets; many appreciate the control, but measurement-focused reviewers argue it is not granular enough to correct all issues.

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 balance is polarizing: some call it even-handed, while measurement-driven reviews point to large deviations (bass and treble boosts and a vocal region dip).

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

Adjustment mechanisms are generally praised for feeling secure and premium, including ratcheting steps that hold position well.

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

Hinges and joints are widely described as robust, with metal hardware that inspires confidence in long-term durability.

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

Included accessories are strong for the price, often including a hard case, soft pouch or bag, USB-C cable, USB-A adapter, and a 3.5mm 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.

Imaging and separation are consistently strong, helping instruments stay distinct even when the overall frequency balance is debated.

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 for the mic is serviceable but not elite; wind and traffic can still be audible unless you speak up.

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 mic quality is usually fine in quiet conditions, but clarity drops in noisier streets or windy situations compared with the best phone-call headphones.

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 quality is mixed: some hear warm, impressive mids, while others report recessed vocals or slightly unnatural timbre depending on tracks and tuning.

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

Multi-device compatibility is a plus, spanning phones and computers and supported by both multipoint Bluetooth and wired inputs.

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

Multipoint generally works reliably, but usability varies: some note the app does not show connected devices or make switching as effortless as certain rivals.

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 solid seal, but it does not fully replace top-tier ANC in louder environments.

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

Most reviews describe foldability that fits the headphones into a protective case, though at least one comparison notes limited folding for ultra-compact packing.

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

Preset profiles like Neutral or Smooth can be genuinely useful for dialing back bass or treble, though some report changes in perceived loudness when toggling EQ.

Replaceable earpads (and sometimes the headband) are called out as a longevity-friendly design choice.

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

Wear-detection sensors support auto pause and resume; behavior can be a little too eager for some, but the feature set is generally appreciated.

Sidetone is available and adjustable, which can help calls for some users even if others prefer it turned off.

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

Smudge resistance depends on finish and handling: some report minimal fingerprints, while others notice visible marks with regular contact.

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 typically painless, with straightforward pairing and a simple app layout; firmware updates are reported as quick and uncomplicated.

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.

Reviews disagree on the overall sound: many praise a warm, detailed, spacious presentation, while others criticize the stock tuning as overly colored and not reference-like. Wired listening via 3.5mm and USB-C is a valued feature; some reviewers prefer the USB-C wired mode for extra clarity and dynamics.

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 described as wide and immersive, with an enveloping presentation; some report even better clarity and space when listening wired over USB-C.

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.

Dolby Atmos and head tracking are a major feature: some find the effect subtle and well executed, while others dislike the tonal shift or report jumpy tracking behavior.

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

Touch controls are usually accurate and easy to learn, with occasional accidental triggers or misfires while moving or when handling the headphones.

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 adjustable and generally useful, though some find the highest setting overly sharp or bright in the upper frequencies.

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 clear and energetic, but can bring sibilance or harshness for sensitive listeners; a few note slight top-end roll-off or prefer EQ to smooth it.

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, in several reviews, for wired audio playback, adding versatility beyond standard Bluetooth listening.

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.

Volume headroom is ample, with multiple reviewers noting the headphones get very loud without obvious strain at typical listening levels.

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

At roughly 319g, weight is noticeable for some listeners and is part of the comfort complaints, though others still consider it manageable.
