Compare Sony WH-CH720N Wireless Headphones vs Bowers & Wilkins PX7 S3 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 repeatedly described as a meaningful improvement for B&W and effective for commuting and travel, but many reviews still place it behind Sony and Bose at the top end. Wind and higher-frequency voices can be weak spots in some scenarios. ANC mode control is straightforward (on, off, pass-through) and can be mapped to a quick-action button in some setups. Reviewers note fewer adjustment options than Sony-style multi-mode systems.

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.

Android compatibility is strong, especially thanks to codec breadth and aptX options. Several reviews contrast this with iOS being limited to AAC.

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.

The companion app is generally considered clean and functional, offering key controls and some ecosystem integration. Multiple reviewers still call it simpler than Sony-style apps and note missing power-user features.

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

aptX support is repeatedly highlighted, including higher-end variants such as Adaptive and Lossless, making it particularly attractive for compatible Android and Snapdragon Sound devices.

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.

Reviewers generally report good sync for video use, with latency described as not an issue for typical phone or laptop watching.

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 consistently described as impactful and controlled rather than boomy, with strong definition. Some listeners find it bass-forward at higher volumes, while others want a bit more sub-bass weight.

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 consistently cited around 30 hours with ANC on, which is solid but not a class leader versus marathon models. Real-world tests generally align with the rating. Multiple reviews note the battery is not user-replaceable, which limits long-term serviceability compared to fully repair-friendly designs.

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 performance is described as stable and reliable in most reviews, including in congested environments. A small number of users report occasional skipping or hiccups, suggesting rare environment or device-specific issues.

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 consistently described as top-tier for the price, with premium materials, refined finish, and sturdy mechanisms.

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.

Physical buttons are a plus for many, with tactile, clicky controls that work with gloves. A few reviews call the buttons small or the control layout limited compared to feature-heavy rivals.

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

Included cables (USB-C to USB-C and USB-C to 3.5mm) are generally seen as premium and practical. A couple of reviewers suggest buying longer cables for desk or airplane use.

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

The hard case is repeatedly called excellent, with premium materials, good protection, and a useful magnetic compartment for cables.

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.

Fast charging is a standout, with many references to short top-ups delivering multiple hours of playback.

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

Clamp is commonly described as moderate-to-firm, helping stability when walking. For some heads it can create pressure points, while others find it secure and comfortable after break-in.

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 a major strength, with broad compatibility (including aptX variants) plus wired USB-C audio options. Several reviews also mention upcoming firmware features like LE Audio, Auracast, and spatial audio depending on region and timing.

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).

Comfort is a consistent highlight, with many reviewers wearing them for hours without fatigue. However, some report firm clamp, earcup heat, or fit variability, especially for glasses wearers or outdoor use.

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 frequently praised as sleek, understated, and premium, with a slimmer profile than prior generations and strong pride-of-ownership appeal.

Detachable cables and USB-C audio add flexibility for laptops and in-flight systems, even without a native 3.5mm jack on the earcup. Most reviews note the headphones typically need to be powered on for wired listening.

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.

Earpads are usually described as plush and premium with good sealing. A few reviews suggest padding feels slightly less supportive than prior models and can get warm over time.

No summary yet.

Swivel and rotation range are frequently noted as generous, helping the cups seal and sit flatter against the head for comfort and stability.

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

The 5-band EQ is widely welcomed as a major improvement over earlier B&W EQ options and is enough to correct stock tuning. Several reviews still consider it limited versus more granular 10-band systems.

Tonal balance is described as neutral-with-warmth by several outlets, while others report noticeable swings and a more consumer-friendly curve. Overall, it is closer to balanced than purely V-shaped, but not a strict reference-flat tuning.

Headband adjustment is smooth and easy to dial in, and padding is generally praised. Some users note mild top-of-head pressure depending on head shape and fit.

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.

Arms and hinge mechanisms are described as sturdy, with premium-feeling movement and good resistance. Long-term durability is generally expected to be strong based on materials.

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 viewed as generous for the segment, typically including a premium case and multiple cables for charging and wired playback.

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 layering are a standout, with reviewers repeatedly noting strong clarity in busy mixes and easy-to-track placement of vocals and instruments.

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.

Multiple reviews point out LDAC is not supported, so LDAC-first Android users may need to choose a different model or use wired playback.

Even at higher volumes, the presentation stays largely clean and controlled, with low distortion noted in multiple reviews. The main caveat is that bass and treble emphasis can become more prominent if you listen loud.

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.

Noise reduction on calls is effective at suppressing background noise, especially wind and street ambience in some demos. The tradeoff is occasional aggressive gating that can alter vocal tone.

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

Call quality is generally solid, with clear voice pickup and good intelligibility. In very noisy or windy conditions, some tests report the voice can sound a bit muffled or less natural than top performers like Sony or AirPods Max.

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 is generally clean and detailed, but multiple reviewers describe it as slightly recessed in the stock tuning; EQ can bring vocals forward. Others highlight the mids as a core strength for clarity and realism.

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 frequently praised as quick and seamless, with fast take-over when switching between phone and computer playback.

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

Passive isolation benefits from an easy-to-achieve seal and helps overall noise reduction. A few notes suggest fit, glasses, or positioning can change results noticeably.

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 mixed: the headphones lie flat and the case is slimmer than before, but they do not fully fold and can take more bag space than foldable rivals.

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.

True Sound and other presets are appreciated for a quick, consistent baseline, but reviewers note the preset lineup is not extensive and serious tuning relies on the manual EQ.

Replaceable earpads are a notable plus for longevity, though some reviewers note replacement may require service or specific procedures.

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

Wear-detect and related sensors are commonly mentioned, with adjustability in the app and improved reliability versus older generations in some reports.

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.

Setup is generally easy, with quick pairing and a straightforward app experience. Firmware updates and feature rollouts are occasionally cited as timing-dependent.

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, the PX7 S3 is praised as one of the best-sounding wireless ANC over-ears in its price range, with an engaging, high-end presentation. A minority note the tuning can feel unconventional until you EQ it. Wired listening via USB-C is supported and often described as clearer or more detailed than Bluetooth, though some reviewers hear only modest gains. A few notes mention wired operation may require power and can be finicky depending on source and cable.

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.

Soundstage is described as spacious and well-layered for a closed-back ANC headphone, though not the widest in class. Several reviews frame it as more focused or intimate than some rivals, with strong depth and imaging.

No summary yet.

Spatial audio is mentioned as a planned or coming-soon feature in several reviews, but availability at launch is inconsistent. In current form, it is not a primary reason to buy.

Materials and serviceable parts (like pads and headband components) are positioned as more sustainable than fully disposable designs. Some reviews also emphasize vegan or leatherette options and longer-term repairability.

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 often called natural and usable for announcements and quick conversations. Several comparisons say it is not the most open or bright in class, with some upper-frequency muffling.

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 widely called airy and detailed with good sparkle. At louder listening levels, a few reviews mention sibilance or sharpness, so treble-sensitive listeners may prefer a mild EQ cut.

USB-C charging is repeatedly noted and treated as the expected modern standard for this model.

USB-C implementation is strong, covering charging and audio, and enabling high-resolution wired playback with compatible sources.

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.

Volume output is strong, with several comparisons calling it louder than key competitors at the same device volume settings.

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.

At roughly 300g, weight is acceptable for the materials and feels lighter than some heavy flagships, but heavier than the lightest Sony/Bose options. A few reviewers notice shifting while moving.
