Compare DALI IO-12 Headphones vs Focal Bathys MG Wireless Headphones

Sound quality was the product’s strongest consensus, with reviewers repeatedly calling it outstanding for wireless headphones.

Reviewers consistently describe the Bathys MG as one of the best-sounding wireless ANC headphones, with especially strong praise for its richer, more energetic presentation versus the original Bathys.

ANC was generally considered useful and capable with low rumbles, but multiple reviewers stressed it is not the product’s standout or class-leading feature.

ANC is judged useful and improved, but not class-leading; reviewers say it reduces buses, traffic and office noise while still letting some voices or mids through.

Bass was widely praised for control, punch, weight, and optional added thump without becoming broadly bloated.

Bass is broadly praised for depth, control, impact and texture, though several reviewers note that default tuning can sound boomy, swollen or resonant before EQ or depending on music.

Soundstage was praised as wide, open, spacious, and unusually impressive for Bluetooth closed-back headphones.

Soundstage is repeatedly described as spacious for a closed-back wireless headphone, with good depth and immersion, though a few reviewers note it remains somewhat intimate rather than speaker-like.

Wind noise handling was a weakness, with one reviewer finding the IO-12 more susceptible than consumer-focused rivals.

Wind noise handling is only average, with one review noting that wind and high-pitched noise pass through more easily than on Sony’s class leader.

Review evidence says ANC can be used without taking a noticeable hit to audio quality.

ANC has little to no negative effect on audio in several reviews, which praise the stable tuning and absence of sonic changes between modes.

Background noise reduction was effective for ambient rumble and daily distractions, though not described as total isolation.

ANC background noise is a positive in the scored review because revised microphones are said to reduce unwanted hiss.

Frequency balance was praised as cohesive, polished, even, and well controlled across the range.

Frequency response is praised for smoothness and coherence, especially in Dynamic mode, though default tuning can add coloration in the lower mids and treble.

Immersion was a clear strength, with reviewers describing the soundstage and presentation as multidimensional, open, and engaging.

Immersive audio quality is praised in the scored review, which describes an expansive, three-dimensional presentation.

One reviewer strongly praised that ANC did not alter the headphone’s sound signature.

ANC mode changes are praised for preserving the sound signature, with multiple reviewers saying the sound remains stable across Silent, Soft and Transparency.

Maximum-volume behavior was praised for headroom, detail, and lack of distortion.

One reviewer warns that very loud playback or sharp recordings can expose the treble response, limiting clarity at big volumes.

Connection and fit stability evidence was positive, with reviewers reporting no dropouts and stable long listening.

Stability is mixed for mobile use because one reviewer reports annoying ANC inconsistency when walking outdoors.

Headband padding had a mild comfort caveat, with one reviewer saying the thin band was uncomfortable at first.

Headband padding is viewed positively in the one scored review, which links the revised foam to better comfort.

Replaceable earpads were praised as a welcome feature for cleaning and replacement.

Replaceable earpads get a mixed mark because removability is welcome, but one review criticizes the lack of included replacement pads.

Portability was a consistent weakness because the headphones are large, do not collapse, and use a bulky case.

Portability is limited by the fold-flat-only design, even though some reviewers find the case slimmer or easier to pack than expected.

Accessories were generally useful, but one reviewer missed a USB-C to USB-C cable.

Included accessories are basic: one reviewer notes the lack of flight adapters, mic cable or special extras.

Looks were divisive: some reviewers liked the smart brown finish, while others found the size and profile awkward or attention-grabbing.

The profile is not very discreet for everyone; one review explicitly says the styling may be too flashy.

Travel friendliness was mixed: sound-on-the-go was valued, but size and packing difficulty were recurring caveats.

Travel friendliness is mixed: the slimmer case, DAC convenience and long battery help, but the fold-flat form and case size still limit portability.

Cable feedback was mixed: one reviewer criticized a cable as janky, while another liked the woven branded cables.

Cable quality is mixed: some reviewers call the included cables acceptable or durable, while another says they are basic and lack premium extras.

Premium feel was consistently supported by high-end build, leather materials, accents, and a luxury presentation.

Premium feel is a major strength, with reviewers describing the product as looking and feeling premium, luxurious and more refined.

The preset Hi-Fi and Bass modes were generally praised, especially the controlled bass boost and audiophile-leaning Hi-Fi mode.

Preset EQ profiles, especially Dynamic mode, are a notable strength for reviewers seeking a more balanced or Harman-like sound signature.

Overall recommendations were positive for listeners prioritizing premium wireless sound, with caveats around price, travel bulk, and features.

Overall recommendations are strongly positive for buyers prioritizing sound, comfort and luxury, while reviewers still caution about price and feature gaps.

Connectivity was a strength, with reviewers valuing the wired, wireless, USB-C, and passive listening flexibility.

Connectivity options are a major strength, with reviewers praising the combination of Bluetooth, USB-DAC and wired listening flexibility.

Midrange clarity was repeatedly praised for resolution, clean layering, vocal realism, and detail.

The midrange is a major strength in most reviews, with vocals, guitars, piano and instruments described as clearer, more powerful and more nuanced than on the original model; one reviewer found vocals somewhat suppressed.

Transparency mode was considered clear and useful for outside awareness without major disruption.

Transparency mode is generally considered effective, making conversations and surroundings audible without removing the headphones.

A passive 3.5mm option was treated as a useful fallback that keeps music available when power runs out.

The 3.5mm analog input is valued as a rare, useful wired option in a premium wireless headphone.

The onboard DAC/amp and active electronics were presented as important to unlocking the headphone’s best performance.

The built-in DAC and hi-res playback mode are among the most praised features, repeatedly described as excellent, useful and a major reason to consider the headphones.

Instrument separation was a standout strength, repeatedly described as outstanding, accurate, layered, and clearly spaced.

Reviewers praise instrument separation, imaging and placement, often saying the Bathys MG reveals layers, positions instruments clearly and keeps complex mixes organized.

The carry case was praised as sturdy, protective, and luxurious, though other evidence notes it contributes to travel bulk.

The carrying case is mostly praised as protective, slim and practical, though one reviewer finds it less premium than some competitors’ cases.

Volume output had positive support, with enough headroom and strong clarity at high volume.

The smaller 3dB volume increments are viewed as a meaningful usability upgrade that helps listeners hit a more precise level.

Treble was generally praised for detail and smoothness, though some brightness sensitivity appeared in one review.

Treble earns mostly positive marks for clarity, shimmer and smoothness, but some reviewers hear occasional sharpness, edge or fatigue with bright recordings or high volumes.

Ear cup padding was repeatedly praised as plush, soft, leather-covered, and comfortable.

Earpad quality is praised for softness, compliance and plushness, though the more compliant pads may let some larger ears brush the inner baffle.

Charging drew mixed feedback because there is no fast-charge mode, but one reviewer liked the long-term battery-protection behavior.

Charging is well received because quick charging reliably adds several hours of playback in about 15 minutes and one reviewer calls charging very fast.

Battery life was viewed as acceptable to good, with 35 hours often described as sufficient but not exceptional at the price.

Battery life is polarizing: many reviewers find 30-plus hours practical or impressive, but others call it disappointing for the premium price.

EQ customization was a weak point because reviewers noted the absence of app-based EQ or deeper profile control.

EQ customization is helpful but limited; reviewers like the usable bands and bass adjustment, while several wish for deeper or parametric control.

Advanced software extras were limited, with reviewers pointing to a bare feature set and lack of app-driven controls.

Advanced software features are a limitation because the app and EQ are simpler than richer rival ecosystems.

The missing app split reviewers: some saw it as a drawback for settings and EQ, while others appreciated the simplicity.

The app receives mixed marks: some reviewers find it solid or useful, while others describe it as limited, brief, glitchy or dependent on personalization.

Voice prompts were useful for battery feedback, especially warning users about charge status before it becomes a problem.

Voice prompts and feedback are mixed: one reviewer wants clearer ANC mode announcements, while another likes the refined connection sounds.

Bluetooth performance was praised for fast pairing, stable connection, and strong wireless sound, though one reviewer noted wireless loses detail versus wired.

Bluetooth performance is generally solid with fast pairing and good aptX Adaptive performance, but reviewers criticize the version and feature set for not being cutting-edge.

Physical controls were mostly praised for responsiveness and usability, with some complaints about accidental presses.

Physical controls are preferred over touch by one reviewer, but another notes the small buttons can be difficult to locate by feel.

Setup simplicity was a strength for reviewers who valued fast pairing and freedom from app tinkering.

Setup simplicity is positive in one review, which says the app made it easy to set the headphones up as desired.

Weight comfort was positive in one review, where the headphones never felt cumbersome despite their size.

Weight comfort is the one weaker comfort note: the headphones are manageable on-head, but one review says their heft is noticeable in-hand.

Durability evidence was limited but positive, with one reviewer reporting the headphones held up through repeated travel.

Durability impressions are positive, with reviewers citing sturdy construction, durable materials and design choices that feel built to last.

Build quality was consistently praised as premium, sturdy, and well executed.

Build quality is consistently praised, with reviewers calling the construction premium, flawless, sturdy and made from high-quality materials.

Comfort was one of the strongest points, with several reviewers calling the IO-12 among the most comfortable over-ear headphones they had worn.

Comfort is a strong point, with reviewers repeatedly reporting long-session wearability, softer pads and better weight distribution despite the headphone’s size.

Design feedback was mostly positive for elegance and distinctiveness, though the brown finish and large form factor were subjective.

Design earns strong praise for its chestnut/bronze luxury look, premium styling and distinctive Focal identity, though one review says the look may be too flashy.

Clamping force was generally praised as secure without becoming overly pressuring or unstable.

Clamping force is generally comfortable and improved versus the original Bathys, with reviewers describing less pressure and a secure but not punishing fit.

Codec support was framed as helpful for minimizing the compromises of wireless listening.

Codec support is viewed as adequate rather than premium; aptX Adaptive helps, but reviewers repeatedly criticize the lack of broader high-end codec support.

Value was highly context-dependent: some reviewers found it worth the premium, while others questioned the price.

Value is debated: reviewers admire the performance and luxury, but the high price, smaller upgrade over the original and missing features make value context-dependent.

aptX support is treated positively in one review because it works well alongside multipoint, but it does not erase broader codec complaints.

Feature depth was mixed to weak: reviewers liked the core experience but noted limited software support and app features.

Headband adjustment was praised in one review for smooth movement and secure positioning.

The integrated microphones are considered effective enough for calls in the scored review, though call quality is not treated as a headline feature.

LDAC is a repeated missing feature, with reviewers saying it should have been included at this price even if not everyone thinks it would transform sound quality.

Multi-platform compatibility is a strength in the scored review because the headphones are described as working across virtually every listening situation.

Pad replacement received positive support, though the evidence focuses on replaceable earpads rather than the headband.

USB-C playback received positive support as part of the IO-12’s high-quality wired digital listening flexibility.

Auracast support is a weakness because one review explicitly notes that the Bathys MG goes without it despite cheaper rivals adopting newer wireless features.

Multipoint is appreciated when it works, but reviewer experience is mixed: some describe seamless switching while others report quirks when moving back to a phone.

Bluetooth version is a weakness at this price, with reviewers noting that 5.2 is improved but not the latest standard.

Call quality is considered good to very good, with voices remaining clear in typical environments, though not always as noise-free as top call-focused rivals.

Lighting customization is present but not universally valued; one review calls the logo light show unnecessary on expensive headphones.

Smart listening features are valued mainly through Mimi personalization, which reviewers say can improve or tailor sound effectively.

Voice assistant integration is present and broadly supported through major assistants, with no major quality complaints in the scored review.

Earpad or cup movement noise is a drawback in one review, which reports a soft thumping sound while running.

LE Audio readiness is weak because reviewers specifically call out the absence of Bluetooth LE, LC3 or related newer wireless standards.

Microphone noise reduction is serviceable and sometimes praised for reducing disruption or hiss, but wind and high-pitched noise still leak through in one review.

Passive isolation benefited from the large earcups and fit, helping reduce outside noise before ANC.

Sustainability materials receive a positive note for the FSC-certified bamboo pulp packaging material.
