Compare Sony WH-CH720N Wireless Headphones vs Sennheiser HDB 630 Wireless Over-Ear 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 performance is generally rated good to very good, especially for low-frequency rumble, but usually a step behind the strongest Sony/Bose/Apple implementations. A minority of takes place it closer to the leaders, while others call it only average for the price. ANC is highly adjustable through the app, with adaptive and manual control plus optional wind-related processing, making it easy to tune for different environments.

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.

The Smart Control Plus app is repeatedly called a standout, bundling EQ, ANC, connection management, firmware updates, and extras like sound zones and find features. A few reviewers mention occasional glitches, especially when the dongle is connected.

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 family support is frequently cited as a major advantage, and the included dongle helps enable higher-quality aptX links on devices that otherwise lack them.

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.

Latency varies by device and mode. With the dongle, it is often good for movies and casual gaming, but several reviews note it is not truly esports-grade and real-world results may sit closer to typical Bluetooth latency.

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 tight and controlled rather than boosted. Some call it punchy and physical, while others describe sub-bass quantity as lean; bass boost and EQ can add weight, but pushing hard can thicken or muddy the presentation.

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 excellent: many quote around 60 hours with ANC, and measured tests still land in the low-to-mid 50s. Hi-res modes and dongle use can reduce runtime but remain strong for the class.

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 mostly stable once paired, with occasional quirks around device switching and initial dongle pairing on some setups.

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 generally solid, but multiple reviews note that materials feel more plastic than premium for the price, and a few mention creaks or rattle.

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 controls are minimal and straightforward, with most interaction handled by touch. Some reviewers wish the lone button were mapped to a different shortcut.

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

Included cables are generally considered useful and of decent length and quality, though a few nitpick terminations or the lack of inline mic support on analog.

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

The carry case is widely praised as sturdy and well-organized with pockets for cables and the dongle; size is the primary drawback.

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 frequently praised for speed, with several reviews citing around 7 hours of playback from a 10-minute top-up and roughly 1.5-2 hours for a full charge.

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 moderate and improved versus Momentum 4, helping stability without feeling overly tight. Fit-dependent seal changes can still affect comfort and tonality.

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 and input support are broad: Bluetooth 5.2 with modern aptX options plus wired USB-C and analog. Not every premium codec is supported everywhere, but overall flexibility is a key selling point.

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 generally strong thanks to thick padding and moderate clamp, but people with larger ears, heat sensitivity, or shallow-pad discomfort may fatigue sooner.

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 understated and professional with matte black and subtle accents. Some appreciate the minimalist look, while others find it plain or less premium-looking than similarly priced rivals.

The BTD 700 dongle is valued for enabling better codecs (especially for iOS), improving perceived resolution, and offering lower-latency modes. Setup can be finicky, the protruding plug raises durability concerns for some, and calls or app behavior may worsen in dongle mode on certain devices.

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 frequently described as thick, soft, and good at sealing for isolation. The tradeoff is increased heat retention during longer sessions.

No summary yet.

Swivel range helps the cups lay flat for storage, but one reviewer notes the rotation can be so free that small asymmetries in fit may affect tonal balance.

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

Equalizer tools are a highlight: a five-band parametric EQ with A/B bypass enables precise tuning that can meaningfully tailor bass and treble without third-party apps.

Several reviewers highlight target-curve or reference-leaning balance and good tonal accuracy. Fit and seal still matter, with small positioning changes affecting bass and lower-mid response.

Headband adjustability is typically smooth and offers enough range to dial in fit, contributing to stable wear.

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 unusually generous for the category: the dongle, multiple cables, adapters, and a robust case are common value-add callouts.

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 recurring strengths, helping dense mixes stay intelligible and improving localization, especially with higher-quality sources.

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.

At higher listening levels, most impressions suggest the sound stays composed and low in audible distortion. A major caveat is that hands-free call modes on some platforms can drop audio bandwidth and make music sound noticeably worse.

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 for calls is generally competent, keeping speech intelligible in moderate noise. Very loud environments and mode changes can still reduce clarity.

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

On standard Bluetooth, most reviewers report clear voice pickup suitable for work calls. Using the dongle or triggering hands-free profiles on certain platforms can degrade call audio or music quality, so results depend heavily on device and mode.

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 performance is consistently praised for clean, realistic vocals and strong detail retrieval. A couple reviewers note a bit of forwardness around 1-2 kHz that can sound slightly shouty depending on fit and seal.

Multi-platform use is a core strength thanks to Bluetooth plus USB-C and analog options, with the dongle helping iOS users access higher-quality codecs.

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 use (two devices) is supported and often works well, but there are limitations when mixing the dongle with other connections and occasional reports of source confusion.

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 is above average thanks to thicker pads and a strong seal, helping even before ANC is engaged.

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: cups lay flat but the headphone does not fold inward, so it takes more space than some travel rivals. The case is protective yet can be bulky.

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 EQ profiles and quick toggles like bass boost are generally effective and easy to use. Power users still prefer the parametric EQ for more surgical control.

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

Wear sensors add convenience (auto play/pause, auto-on), but sensitivity can cause accidental wake-ups for some; most note these features can be disabled.

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.

Smudge handling is mixed: matte cups are often described as fingerprint-resistant, but some materials (notably the headband on some units) can pick up grease and grime easily.

Setup is usually straightforward, but dongle pairing steps and occasional app quirks can add friction. Some advanced features require extra steps (like enabling specific audio modes) depending on device.

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: balanced, highly detailed, audiophile-leaning tuning that competes with top wireless flagships and scales up with the dongle or USB-C. A few reviewers find it less instantly exciting than bass-boosted rivals, but overall fidelity is widely praised. Wired playback (especially via USB-C) is often cited as the cleanest, most resolving path. Analog input works too, but the headphone typically still relies on internal DSP and battery power.

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 considered roomy for a closed-back wireless, with better depth and separation than Momentum 4; crossfeed and the dongle can change the sense of space. It still cannot match open-backs, and a few listeners describe it as more in-head than speaker-like.

No summary yet.

Spatial audio as a dedicated virtualized mode is often noted as absent; instead, Sennheiser emphasizes EQ and crossfeed-style processing for older mixes.

Touch controls are feature-rich, but experiences vary widely: some find them refined and responsive, while others report misreads or frustration with pinch-based ANC gestures.

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 typically described as usable and convenient, with adjustable levels and quick toggles. It is rarely considered best-in-class for naturalness, and some reviewers rate it merely adequate.

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 often described as detailed and generally well-controlled. Opinions diverge: some hear extra energy up top or a dip in the mid-treble that can make the presentation feel a touch closed-in, and sensitivity varies by listener and fit.

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

USB-C is a versatility highlight for both charging and wired digital audio, and is frequently cited as the cleanest connection option.

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 integration is supported and typically works as expected via a dedicated button or gesture.

Volume output offers solid headroom and gets loud enough to help overcome moderate ambient noise. Heavy EQ boosts can reduce available peak volume due to protective preamp behavior in the app.

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.

No official water or sweat rating is typically noted, so these are better treated as commute and travel headphones rather than workout gear.

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 311g, weight is noticeable but often well-distributed. Some still prefer lighter competitors for all-day travel comfort.

Xbox support is commonly described as limited, with at least one review noting the dongle route does not work on Xbox.
