Compare Sony WH-CH720N Wireless Headphones vs DALI IO-12 Headphones

ANC is generally rated as strong for the price and especially helpful against low-frequency hum/rumble, but it is not consistently described as flagship-grade and can let in some noise (notably on flights or distant traffic). Some reviews highlight granular ambient/ANC controls in the app and adaptive behaviors, while others focus on simple mode toggling. Overall adjustability is viewed as good for the price.

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.

Compatibility is framed as mainstream-friendly across phones and computers via Bluetooth and a 3.5mm jack; Android-specific advantages are primarily discussed in the context of codec support in one source.

The Sony companion app is repeatedly cited as a major value add, offering EQ, feature toggles, and adaptive behaviors; one review notes account requirements for full access.

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

Multiple reviews explicitly call out that aptX (including low-latency variants) is not supported, positioning these as more mainstream than enthusiast-focused for codecs.

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.

Several sources imply this is not a gaming/low-latency-focused headset, noting missing low-latency modes/codecs. At least one review says video sync issues are minimal for most people, but latency could be better.

Bass is frequently emphasized: some praise punch and warmth, while others describe it as boomy/loose or overwhelming without EQ, and not as controlled as higher-end options.

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 consistent strength. Multiple reviews cite around 35 hours with ANC on, and at least one measured test lands near 40 hours.

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.

Once paired, Bluetooth stability is generally reported as solid, with stable connections across typical use; a few note initial pairing quirks on some devices.

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

Build is the most common compromise: many describe a plasticky, budget feel (sometimes even 'toy-like'), while others find it sturdy enough with minimal creaks. Durability concerns come up often.

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 broadly seen as reliable and easy to use. Multiple reviewers note the buttons can feel similar, causing occasional mis-presses until you learn them.

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.

Cables are generally considered usable, though at least one review calls out the included cables as short for some desk/PC setups.

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 recurring complaint is the lack of an included carrying case/pouch, pushing buyers toward aftermarket protection if traveling.

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 top-ups are a highlight across several sources, commonly described as roughly an hour of playback from a very short charge. Full recharge times are described as reasonable for the class.

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.

Most describe a secure but not crushing clamp that stays put; a minority warn glasses wearers may feel pressure.

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 described as limited at this price tier (often AAC/SBC), with repeated mentions that premium/low-latency options are missing.

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 widely praised, especially for all-day desk use and commuting. A few note heat/stickiness over time or fit sensitivity (glasses pressure, ear contact for some).

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 generally described as minimalist and attractive enough for everyday wear, with common color options and a clean look that reads more understated than flashy.

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.

Padding is generally described as decent for the price, though several reviews call it thinner/less plush than premium models and some mention it can feel sticky with longer wear.

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

No summary yet.

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 control is frequently praised as effective, with several reviewers recommending EQ tweaks to reduce treble fatigue or rebalance bass/mids.

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

Hinge/long-term durability is frequently treated as a watch-out due to light plastics and the non-folding design; at least one review warns pressure on the swivel/hinge could risk breakage.

In-box accessories are usually described as basic: commonly a USB-C charging cable and a 3.5mm audio cable, with no case included.

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 generally framed as good for casual listening but not class-leading; several reviews explicitly say separation/resolution trails more expensive models.

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

Most reviews state there is no LDAC/hi-res support, but one review explicitly lists LDAC among available codecs. Treat LDAC support as inconsistent across sources and confirm if it matters to you.

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 for calls is described as above average for the class (including some wind handling), but multiple sources say it can struggle in very noisy settings like loud cafes or heavy traffic.

Call mic quality is generally reported as good for a built-in headphone mic, with clear speech in typical environments.

Midrange is a mixed bag: several say vocals can be strong or pleasant (especially after EQ), while others report recessed or slightly muffled mids in the default tuning.

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 is repeatedly mentioned as a key convenience feature and usually works well, though some report occasional switching wobbles that resolve on a second try or after enabling it in-app.

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 typically described as decent but limited by lighter padding versus premium models, making ANC do more of the heavy lifting.

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.

Most sources emphasize the headphones do not fold, typically only swiveling flat, which hurts packability even though the low weight makes them easy to carry.

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 described as useful but can be taste-dependent; at least one review notes a preset can make bass or treble feel overcooked until adjusted.

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

Wear-detection sensors are repeatedly called out as missing, and auto-pause features are often described as reserved for higher-end Sony models.

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.

Finish-related notes vary: some mention a matte texture that helps with fingerprints, while at least one review warns lighter colorways can pick up dirt and need cleaning.

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 described as enjoyable and competitive for the price, often bass-forward and lively. Many recommend using EQ to refine balance; multiple reviews still note limits in dynamics, resolution, or naturalism versus premium models. Wired listening via 3.5mm is supported and generally works well when powered. Some notes suggest passive/off listening changes the sound and is less impressive.

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 wider than expected for the price, while others describe it as narrower/compact compared to Sony flagships, with depth often the weaker dimension.

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.

No summary yet.

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.

Transparency/ambient mode is often described as effective and natural for the price, though a few mention mild hiss or a slightly processed effect.

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

Treble is often described as clear but can be boosted/peaky and fatiguing for some listeners until EQ adjustments tame it; others find it smooth enough for longer sessions.

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 repeatedly noted and treated as the expected modern standard for this model.

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 mentioned across reviews (e.g., triggering assistants via button hold), and is treated as a standard convenience feature rather than a headline differentiator.

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

Water/sweat resistance is described as absent (no waterproof rating), and at least one review cautions against heavy sweat, making them a fair-weather choice.

A consistent standout: reviewers repeatedly call these exceptionally light for over-ears (around the ~190g range) and easy to wear for long sessions.

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