Compare 1MORE SonoFlow-Pro Headphones vs DALI IO-12 Headphones

ANC is widely viewed as strong value and most effective against low-frequency rumble (engines, bus/train noise); it is less consistent with speech and higher-frequency chatter, and a few reports mention performance limits or inconsistency in very loud environments. Most reviews describe simple mode switching (ANC on, off, transparency) without multiple strength levels; tonal balance can shift when toggling modes on some units.

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.

The companion app enables key features (EQ, modes, LDAC, shortcuts), but experiences vary: some find it helpful and improved, while others report confusion across app versions, unreliable connections, or lag.

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

Multiple reviews listing codec support note that aptX is not supported.

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.

Latency is generally well controlled for video; gaming/low-latency modes are reported to help keep audio and visuals in sync with minimal delay.

Bass is a defining trait: usually deep, punchy, and satisfying, but it can edge into muddier territory on some tracks or modes; EQ settings are frequently used to rein it in for a cleaner balance.

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 a standout, commonly cited around 60–65 hours with ANC on and up to ~100 hours with ANC off; multiple reviewers verified ~61 hours ANC-on in real use, while enabling LDAC can reduce runtime.

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 connections are generally stable with good everyday range, though a few reviewers note quirks tied to codec selection or less reliable behavior when dual-device features are enabled.

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

Build quality is generally solid for the price (often plastic with an internal metal band), but reviewers are split between sturdy and slightly flimsy/creaky impressions depending on expectations and unit tolerance.

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.

Physical buttons are generally easy to locate and clicky, but some feel plasticky or wobbly; mode chimes/voice prompts and long-press power behavior are common usability complaints.

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 works but uses a non-standard 2.5mm headphone-side connector; several reviewers dislike the format for convenience, replacement options, or length.

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.

A hard case is typically included and appreciated, but some reviews call it simplified (no internal pouch/pocket) or less premium than earlier bundles.

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 is fast and convenient, with multiple claims of a short top-up delivering several hours of playtime and full charges landing around 70–80 minutes in tests.

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 trends light-to-moderate and often comfortable, but can feel loose for active movement or, for some heads, slightly tighter than expected.

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 commonly listed as SBC and AAC plus LDAC for higher-quality Android streaming; aptX is not included in the codec lists cited in these reviews.

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.

Comfort is a consistent strength: light weight and plush padding support long sessions (including all-day wear in one review), though a few mention warmer pads or slightly higher clamping pressure.

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 generally seen as sleek and understated with a clean matte/plastic finish; some describe it as generic, but still modern and tidy for the price.

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.

Ear pad padding is usually described as plush and roomy, but some users find the pleather less breathable and prone to warmth/sweat over time.

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

Earcups swivel/rotate to improve fit and to fold flat for storage, also making neck-wear more comfortable when not actively listening.

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 customization is a major upside, with multi-band custom EQ and genre-style options; it is frequently used to tame bass and improve mid/treble balance.

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

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 typically offers a usable range with secure notches/clicks, making it easy to fit different head sizes.

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

Build movement can range from solid to a bit creaky; some reviewers praise improved hinges and reduced self-noise, while others still notice occasional creaks or squeaks.

Included accessories commonly include a hard case, USB-C charging cable, and a 2.5mm-to-3.5mm audio cable, which strengthens overall value at this price.

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 acceptable for the class and improves with better sources/codecs, but heavy bass or certain ANC/EQ shifts can blur busy mixes.

Instrument separation and imaging are consistently praised, with precise placement and clear spacing between layers even in complex mixes.

LDAC is a major feature highlight and can add detail, but it can reduce battery life and some reviewers report difficulty enabling or maintaining LDAC on certain phones or via the app.

Clarity at louder volumes is often described as solid for a sub-$100 headphone, though at least one reviewer noted the sound can lose composure at very high gain levels.

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 helps keep speech understandable and can handle some wind, but background sounds are not fully removed and some processing artifacts are reported in louder conditions.

Call mic quality is usually serviceable and intelligible, but can sound slightly sibilant, digital, or less natural in noisy settings; at least one review notes the inline cable mic performs poorly.

Midrange is typically decent but often a bit recessed relative to the boosted lows; several reviewers say EQ can bring vocals forward, while at least one notes reduced upper-mid presence compared to the earlier model.

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.

Multipoint/dual-device use is supported and helpful when it works, but reviewers describe it as hidden or experimental and sometimes buggy depending on device/app/firmware.

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

The ear pads generally form a good seal with minimal leakage, providing solid passive isolation that complements ANC for commuting and home/office use.

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.

Foldability makes the headphones easy to pack, and the travel-focused design is repeatedly praised for portability.

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.

Preset EQ options are plentiful and can be useful starting points, but reviewers disagree on quality and presentation, with some calling them skippable or poorly explained.

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.

At least one review notes that the ear pads are removable, suggesting they are replaceable if worn.

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

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.

Initial setup is usually straightforward, but confusion between 1More app variants and occasional connection/lag issues can make software setup feel inconsistent.

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 is impressive for the price, leaning warm and bass-forward with generally clear mids and highs; a few reviewers describe a slight veil/muffle (especially wireless or with ANC EQ shift), while wired listening or EQ tweaks can tighten things up. Wired listening can sound clearer than Bluetooth in some reviews and serves as a practical backup; reports differ on whether passive wired works when fully depleted versus requiring power for ANC/EQ.

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 impressions vary: some call it surprisingly wide for a budget set, while others find it fairly narrow/shallow compared with premium competitors.

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 present in the app, but is often described as mediocre or best left off due to sound-quality tradeoffs; a minority find it a fun extra for movies.

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.

Sustainability/packaging draws criticism for plastic wrapping and a perceived lack of eco-focused materials choices.

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 generally useful and can sound quite natural in some reviews, but others report hiss, mild occlusion, or a less realistic passthrough.

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

Treble is generally clean and non-fatiguing, but can be slightly rounded or lacking sparkle; some find highs a touch recessed, especially versus pricier headphones.

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 charging is standard across reviews and contributes to quick top-ups; USB audio over the USB-C port is not described as supported.

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

Volume is usually sufficient for everyday listening, but one reviewer reported that maximum output was not enough to overcome airplane cabin noise.

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

No water/sweat resistance rating is repeatedly noted, so these are better suited to commuting/desk use than workouts or rain-heavy scenarios.

At roughly 246g, weight comfort is generally excellent and reduces fatigue; an older-model review mentions a headband-heavy feel, but most comments emphasize the lightweight build.

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