Compare Sony INZONE H9 II Wireless Gaming Headset vs DALI IO-12 Headphones

Across reviews, ANC is consistently described as unusually strong for a gaming headset, effectively cutting low rumbles and much of the surrounding office or home noise. Several reviewers say it helps them miss voices and distractions even at moderate volume. Noise canceling can be toggled and adjusted via onboard controls and companion software. Tuning options exist, but some reviewers note mode feedback relies on chimes rather than clear voice prompts, which can be confusing.

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.

App support includes a PC-focused hub and a mobile companion, giving access to EQ, profiles, and certain feature toggles. Several reviewers mention that settings can overwrite between apps or feel barebones, but the core control options are there.

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

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.

Audio-video sync and latency performance are repeatedly praised when using the 2.4GHz dongle or wired connection, making it well-suited to competitive play. Bluetooth is positioned as secondary, with LE Audio helping but not replacing the dongle for lowest latency.

Bass is generally punchy for explosions and gunfire, but impressions vary by default profile: some find it underwhelming, others say it can get muddy or overbearing in certain mixes. Most agree EQ can dial in a better 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 commonly rated average for the price: about 30 hours quoted, but real-world results vary widely by ANC and usage, with heavy ANC sessions dropping into the teens and ANC-off testing stretching much longer. Many comparisons note rivals at similar prices last significantly longer or offer hot-swap batteries.

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 connectivity is generally described as quick and reliable for phones and secondary devices. It is often used for music or chat while gaming through the dongle. Simultaneous dongle plus Bluetooth audio is a major highlight, enabling dual-source setups for game audio plus phone audio. Reviewers generally find it genuinely useful for modern gaming routines.

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

Build quality gets a generally positive but not luxury verdict: the headset is light and often described as well-made, yet its plastic construction can feel hollow or less premium than heavier competitors. Durability is usually considered adequate for normal use.

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.

Control usability is mostly praised thanks to distinct shapes, spacing, and tactile buttons, especially for mic mute and game-chat balance. Complaints center on a finicky volume wheel in some contexts and chime-based feedback that can be hard to interpret.

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.

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.

Carrying case quality is typically described as a soft pouch or bag, sometimes with useful pockets, but not as protective as a hardshell case at this price. It is functional for light travel rather than rugged protection.

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.

Fast charging is a clear plus, with multiple reviews citing a short top-up yielding meaningful play time. Full charge times and use-while-charging behavior are reported inconsistently across sources, but quick top-ups are broadly praised.

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.

Clamping force is generally low, which improves comfort and reduces hotspots. The tradeoff is that a few reviewers experienced minor shifting during movement.

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 functional rather than audiophile-focused: reviews mention standard Bluetooth codecs plus LE Audio support, but also note the absence of premium options like LDAC or aptX. This aligns with its gaming-first positioning.

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 during long use is one of the strongest consensus positives, with many calling it among the most comfortable premium headsets they have tested. The lightweight chassis and breathable materials are repeatedly credited for marathon sessions.

Long-session comfort is one of the most consistently praised aspects, with roomy earcups and plush pads that avoid pressure points for many listeners.

Design is often described as understated and premium-looking for a gaming headset, especially with the mic removed, and available in multiple colorways. Some dislike the headband aesthetic or note finishes that show marks easily.

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.

The detachable boom mic is a practical plus for portability and aesthetics, letting the headset look more like regular headphones when removed. Some reviewers still prefer a stowable design to avoid misplacing the mic.

The USB-C 2.4GHz dongle is consistently valued for low-latency, stable wireless on PC and supported consoles. Its PC/Other switch is frequently mentioned as convenient for moving between devices.

Earcup padding is widely praised for being plush, deep, and often breathable fabric, helping reduce heat build-up. The extra depth also helps keep ears from pressing into inner surfaces compared with some Sony over-ears.

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

Earcup swivel range is a standout, with several reviewers noting full rotation and the ability to lay the cups flat in both directions. This helps with neck resting and storage in the included pouch.

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.

Equalizer customization is robust enough to meaningfully change the headset, typically via a 10-band EQ and saved profiles. Many reviews recommend using EQ to broaden the headset beyond its FPS-oriented default sound.

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

Frequency response accuracy is a recurring critique: several reviews describe a non-neutral, gaming-first curve with missing ear-gain style presence and other deviations. This is a major reason music listening is often rated only okay without EQ.

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.

Game-chat balance controls are appreciated on compatible platforms for quick in-match tuning. However, there are reports of limited functionality or weaker integration on certain consoles, reducing its usefulness outside PC play.

Headband adjustability is generally innovative and secure, using a suspension-style system. Some reviewers love the quick locking adjustment, while others find fine-tuning while wearing the headset a bit fiddly.

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

Hinge durability is typically considered solid for a lightweight design, with spring-like mechanisms and enough flex to handle normal handling. A few notes suggest the adjustment mechanism can be finicky rather than fragile.

Included accessories are generally strong, commonly including the low-latency dongle, detachable mic, charging cable, and an analog cable. Several reviewers appreciate the long analog cable and the storage pouch layout.

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 and imaging are frequently highlighted as strengths for positional awareness, helping footsteps and directional cues stand out. A few reviewers still say top competitive headsets can render footsteps even more distinctly.

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

Maximum-volume clarity is generally viewed as solid, with reviewers noting low harshness and reduced fatigue even when playing loud, high-intensity FPS content. Some treble roughness can appear depending on preset, but it is not widely described as piercing.

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.

Microphone noise reduction is often praised for isolating voice and suppressing background noise, including fans and nearby activity. A few real-world tests in loud, crowded spaces suggest performance can vary and may not remove all ambient chatter.

Microphone quality is widely viewed as good to excellent for in-game chat, Discord, and even work calls, with a noticeable jump over the original H9. A minority describe it as only serviceable in very noisy environments or slightly muffled compared with the very best mics.

Midrange presence can feel recessed or muted in default tuning, especially for music and lead instruments. Reviewers who used the custom EQ report it can restore clarity and presence.

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.

Multi-platform compatibility is strong for PC and PlayStation, with support also discussed for Nintendo Switch when docked and typical Bluetooth devices. The notable exception is Xbox compatibility.

Multipoint is repeatedly called out as not supported, which is a downside for users who want seamless multi-device switching. The headset instead leans on dual-connection workflows with the dongle and Bluetooth.

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

Passive isolation is mixed: the pads and seal help, but the light clamp and airy fit mean it is not the most cocooning on its own. Many reviewers frame ANC as the key to strong isolation on this model.

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.

Portability is decent but not compact: the cups lay flat and rotate well, but the headset does not fold down like some travel headphones. It is easy enough to pack in a bag, just not optimized for small cases.

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 profiles are frequently criticized as too FPS-centric and limited in variety, even if some presets help highlight footsteps. Several reviews wish for better presets for music, RPGs, or cinematic games.

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.

Replaceable earpads are confirmed and appreciated by multiple reviewers, including reports of easy pad removal and replacement. A few sources still wish the overall serviceability were more standard across the whole headset.

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.

Sidetone control exists but is not perfectly tuned out of the box, with reports of a low default level and a robotic quality when pushed too high. Many users will want to adjust it to a comfortable middle setting.

Smudge resistance is a consistent nitpick on certain finishes, with multiple mentions of surfaces showing fingerprints or marks easily. Buyers who care about keeping gear pristine may need to wipe it down often.

Setup is often described as fast and straightforward, especially via the dongle. The software experience is more mixed, with some calling it basic, confusingly organized, or requiring extra steps for spatial personalization.

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 quality is praised for competitive play with clear cues and satisfying impact, but default tuning is often viewed as FPS-focused rather than all-purpose. For music and non-FPS games, several reviewers recommend EQ tweaks to avoid a dark or uneven presentation.

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 width is generally regarded as good, creating convincing left-right placement in games. Some reviews note vertical positioning is less precise than horizontal placement.

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 features include virtual surround and Sony 360-style personalization options, plus PS5 3D audio support in some setups. Benefits are mixed: some enjoy wider immersion, while others find the ear-photo personalization process cumbersome or not worth the effort.

Fit stability impressions vary: some reviewers find it secure and stable thanks to the new headband and low weight, while others report the earcups can shift slightly because of the gentle clamp. Overall stability is good, just not vice-like.

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.

Control surfaces are generally responsive; some coverage mentions touch-style control areas, but overall interaction is described as clicky and deliberate rather than finicky.

The headset offers an ambient or awareness mode, but multiple reviews say it is not a true, voice-forward transparency mode. It can let in general room sound, yet holding real conversations is often easier by removing the headset.

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

Treble is commonly described as safe and fatigue-resistant for long FPS sessions, but can sound crunchy, dull, or lacking sparkle depending on the preset. EQ adjustments tend to improve perceived detail for broader listening.

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 is used for charging and the included low-latency dongle. Some reviewers call out limitations like the lack of USB audio in certain scenarios.

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 output is typically sufficient and can get loud, though a couple of reviewers describe it as slightly quieter than expected compared with older models. Overall, most report enough headroom for gaming and media.

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

Weight comfort is excellent, with multiple reviews emphasizing the very light feel around 260g and how little it disappears during play. This low weight is frequently framed as a major advantage over heavier rivals.

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

Multiple reviews explicitly state the dongle does not work with Xbox consoles, limiting native Xbox compatibility. Wired fallback may exist, but the main low-latency wireless path is not Xbox-ready.
