Compare Nothing Headphone (1) vs DALI IO-12 Headphones

ANC is broadly considered strong for the price and effective for travel/commuting, but it is usually ranked a step behind the best from Sony/Bose/Apple, especially for voices or tougher scenarios. Noise control modes and adjustability are a highlight: reviews repeatedly mention multiple ANC levels/adaptive behavior and the ability to map controls to switch modes.

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 Nothing X app is repeatedly described as one of the best parts of the experience, with feature access, customization, and settings that help compensate for default tuning.

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.

Several reviews mention low-latency or gaming modes and head-tracking features; real-world A/V performance is generally positioned as competent, not a class-leading differentiator.

Bass is usually described as controlled and textured rather than skull-rattling, with bass-enhancer tools available; some reviewers still want tighter tuning out of the box.

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 highlight, with many reviews citing long runtime (often around 35 hours with ANC and far more without) and strong real-world endurance. Replaceable battery support is generally weak, with at least one review calling out a non-user-friendly internal battery design.

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 stability is generally good with modern pairing features, though a few reviews mention occasional dropouts depending on environment or device.

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

Build quality is generally seen as solid and premium-feeling for $299, though some reviews note more plastic than expected or worry about long-term cosmetic wear.

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 controls (roller + paddle + buttons + power switch) are a major highlight for tactility, but a few reviews mention learning curve, finicky behavior, or coarse volume steps.

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.

Included cables are generally viewed as fine, though at least one review notes limitations (such as a 3-pole 3.5mm cable that does not carry mic).

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.

The case is usually described as sturdy and protective with space for cables, but multiple reviewers call it large or mention zipper/material quirks.

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 frequently praised, with multiple reviews citing a short top-up delivering hours of playback; full-charge times are generally described as typical.

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 commonly described as secure without being overly tight, though individual fit can vary and some users still feel pressure over time.

Clamping force is usually described as secure but comfortable, ranging from light to moderately firm depending on the reviewer, without feeling unstable.

Codec and connection support is repeatedly highlighted as a strength, with common mentions of SBC/AAC/LDAC and both USB-C and 3.5mm wired options.

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 often rated good-to-very-good for long sessions, but the weight and occasional headband/pad pressure points mean not everyone finds it as effortless as the lightest competitors.

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 consistently described as distinctive and polarizing, with many praising the transparent, cassette-like aesthetic and premium look 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.

Having both USB-C audio and a 3.5mm option is repeatedly praised for flexibility, especially for laptops, planes, and modern phones.

Ear pad comfort and seal are regularly praised, though some reviews mention thinner cushioning than expected, heat buildup, or pressure on certain ear shapes/accessories.

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

Cups generally rotate to lie flat, which helps neck-wear and packing, but the design can cause the squared corners to bump or rattle against each other.

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 defining strength: multiple reviews highlight an advanced, multi-band/parametric-style EQ (often with Q control) plus shareable presets/QR codes.

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

Find My-style features are generally limited to making the headphones play a sound, which helps for nearby locating but is not a full tracker replacement.

Measured and subjective impressions frequently point to a non-neutral stock response (often described as dark), with EQ being the practical path to a more accurate balance.

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 works smoothly for most, but at least one review dislikes the adjustment ergonomics and others wish for more headband padding.

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

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 often praised as solid or good once the tonal balance is corrected, though some reviewers still find complex mixes can feel crowded compared to top rivals.

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

LDAC support is consistently called out across reviews and is a core part of the product’s high-res pitch for compatible Android devices.

At higher volumes, several reviewers report low distortion and clear playback, though ultimate refinement and dynamics are not always on par with premium flagships.

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.

Mic noise reduction is usually strong for steady noise and wind, but some reviews report aggressive noise gating or weaker handling of echo/reverberant rooms.

Call quality is often described as clear and workable, with some reviews praising voice pickup in noisy streets; others call it merely average or slightly robotic compared with top rivals.

Midrange performance varies by tuning: vocals can sound clear and forward after tweaks, but several reviews note too much lower-mid presence or a dull/veiled midrange on default settings.

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 commonly cited as supported and functional, enabling quick switching between two devices; reliability feedback is mostly positive.

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 consistently strong thanks to a good seal and memory-foam style pads, meaning ANC has a solid foundation in many real-world environments.

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 a weak spot versus foldable rivals: cups rotate flat but the headphones do not fold up, making the carry footprint and case bulkier.

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 profiles and simpler EQ tools are generally helpful, but several reviewers still prefer custom EQ to get the best tonal balance.

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 earpad support is mixed: some sources mention pads can be removed or obtained via customer service, while others say replacement availability is unclear.

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

Wear-detection and other sensors work well for many users, but some reports mention inconsistent behavior on specific devices (for example, desktop pairing scenarios).

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.

Surface oils and cosmetic marks can show up on the materials, with some reviewers noting it wipes off easily but is not especially resistant to smudging.

Setup is usually straightforward thanks to modern pairing features, though a few reviews note hidden settings or small/hard-to-find pairing controls.

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.

Sound quality is widely seen as good hardware with polarizing default tuning: some hear clean, balanced clarity, while many describe the stock sound as dark/flat or a bit compressed until EQ is applied. Wired listening over USB-C and/or 3.5mm is frequently mentioned; some reviewers note slightly improved clarity when wired, but not a dramatic transformation.

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 is generally not class-leading; multiple reviews call it narrower or less expansive than Sony/Apple competitors, even if separation can be decent after tuning.

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 included and often paired with head tracking, but opinions on its usefulness vary widely; several reviews call it mediocre or not worth using for music.

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 signals are limited in reviews: some note repairability steps (like pad access) but also a lack of recycled materials or overt eco focus.

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 usable and fairly natural, but a recurring complaint is that the wearer’s own voice can sound boomy and/or the passthrough can be less airy than the best implementations.

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

Treble is a common critique in default mode, with multiple reviewers calling it muted or lacking sparkle; EQ can restore more air and bite for cymbals and vocals.

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 a frequently praised feature because it supports charging and USB-C audio, adding modern wired flexibility.

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 hooks and programmable button behavior are widely mentioned, with extra integrations for Nothing phones and more basic assistant triggering on other devices.

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 generally adequate, but at least one review notes limited headroom and less precise volume stepping than some competitors.

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

IP52 is a standout feature in this category and is repeatedly praised as practical for sweat and light splashes, even if it is not a high waterproof rating.

At ~329g, weight is noticeable: reviewers often say it’s lighter than AirPods Max but heavier than Sony/Bose alternatives, which can affect long-wear comfort.

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