Sony WH-CH720N Wireless Noise-Canceling Over-Ear Headphones, Black (WH-CH720N/B)
Consider the WH-CH720N for lightweight wireless listening, app-adjustable sound, ANC and switching between a phone and computer. Its analogue cable offers a battery-empty fallback, but passive sound changes and the supplied cable does not carry the headset microphone. Avoid it for wet exercise, USB-audio requirements or uninterrupted listening during charging. Try the fit and plan how its non-folding shape will travel.

Conditions and limitations
Wired electrical specifications change with power state
- Capability
- Wired listening works with power on or off, but impedance, sensitivity and available noise-control functions are mode-dependent.
- Limitations
- Passive mode has no ANC and is not sonically equivalent according to the cited listening review.
- No external-amplifier maximum-output measurement was collected.
- Requirements
- For powered wired use, apply 325 ohm and 108 dB/mW; for passive use, apply 31 ohm and 99 dB/mW. Impedance values are specified at 1 kHz.
- Use the 7–20000 Hz JEITA response specification only for powered-on cable operation.
Battery numbers need mode and test conditions
- Capability
- Sony's conditional 35/50-hour music figures and GSMArena's AAC measurements answer different test conditions.
- Limitations
- GSMArena did not disclose playback volume, firmware or sample count in the cited text.
- Charging prevents operation, so a charge break is still needed.
- Requirements
- Identify ANC/Ambient Sound status and processing settings before comparing runtimes.
- The 5.85-hour observation follows a 10-minute charge from 0%; it is not a full-charge measurement.

The review
Sony WH-CH720N: useful ANC and battery flexibility, with important wired-mode limits
Start with your everyday routine
The WH-CH720N combines Bluetooth listening, adjustable sound and noise control in a headset Sony specifies at approximately 192 g. That makes it worth considering for a desk, a commute or ordinary portable listening. The companion app provides EQ, CLEAR BASS and DSEE controls, so you can adjust its presentation rather than being limited to the default balance. [7], [9], [1]
Comfort remains personal: Headphonecheck's positive fit report is one tester's experience. HIFI.DE also found that identifying the physical buttons by touch took practice. Before buying, try the contact and controls during a normal session, then check the packed size. The cups swivel, but the headset does not fold inward, and the cited review reports no carrying case. [6], [1]
Separate listening impressions from measured performance
HIFI.DE found the sound enjoyable while identifying fine-detail limits. GSMArena described a warm, bass-heavy balance that changed when ANC was disabled. These are attributed listening impressions rather than a universal tuning verdict. The app's EQ is useful for exploring preference, but its presence does not establish reference-grade accuracy or erase differences between listeners and recordings. [9], [1], [8]
ANC is documented, but it should not be treated as a promise of silence in every environment. Headphonecheck heard unwanted background noise in direct wind. Comparable calibrated attenuation, leakage and distortion data were not verified in this research, so no numerical isolation guarantee is assigned. Consider your actual surroundings rather than assuming the same outcome everywhere. [9], [6]
The cable is useful, with different rules from Bluetooth
The supplied analogue cable allows listening with the headset powered on or off. ANC and Ambient Sound need power, while passive mode keeps basic audio available when the battery is empty. Headphonecheck heard a muffled, mid-heavy change in passive operation. USB-C does not offer another listening route: it is for charging, not music playback. [4], [6], [1]
Do not merge the two wired electrical modes into one specification. Sony gives 325 ohm and 108 dB/mW with power on, compared with 31 ohm and 99 dB/mW with power off. The published wired frequency-response specification is also scoped to powered-on use. For a cable-connected phone call, speak into the phone's microphone and use the source device for playback and volume. The supplied cable is not an equivalent replacement for Bluetooth headset calling. [7], [4]
Read battery results with their conditions attached
Sony lists up to 35 hours of music with ANC or Ambient Sound enabled and up to 50 hours with both off, for the listed AAC and SBC modes. EQ, DSEE and voice-triggered assistance can reduce those figures. GSMArena's 2023 AAC test reached 47.15 hours with ANC enabled. That longer observation is useful evidence, but the publication does not state playback volume or firmware, so it cannot be substituted for a guaranteed personal runtime. [5], [8]
GSMArena also recorded 5.85 hours after its separate short-charge test from an empty battery. Keep that result separate from the full-run measurement. Sony specifies approximately 3.5 hours for a full charge and says the headset cannot operate while connected for charging. A long battery life therefore helps with planning, but does not provide continuous use through the charging break. [10], [8]
Set up switching, and remember to pause
Bluetooth 5.2 with SBC and AAC supports a two-device multipoint routine through the companion app. Sony's instructions say to stop the first music source before starting the second; the feature does not mix simultaneous streams. Adding a third device replaces one connection while preserving the device that last played music. This priority behavior is worth testing with your own phone and computer before relying on it at work. [7], [2]
Headphonecheck found calls useful in its everyday office and mobile use, but that is not a guarantee for every noisy setting. GSMArena's test also noted the absence of automatic pausing when the headphones are removed. Make manual pause part of your routine rather than assuming that taking them off stops playback. The app supports firmware updates, but the evidence does not establish a promised support end date. [9], [6], [8]
Keep wet use and long-term repair expectations realistic
Sony explicitly says the headset is not waterproof and warns against rain, snow and sweat soaking. It is therefore unsuitable when wet use is a requirement, regardless of whether the fit feels secure. Follow the supplied-cable and compatible-charger instructions, including direct connection rather than a USB hub. [10], [3]
The battery is built in. Sony recommends dealer consultation when endurance deteriorates substantially and periodic charging during long storage. Before making a repair-dependent purchase, check what service is actually available locally. The instructions do not establish replacement stock, fixed charges or lifetime durability, and those unanswered questions should stay separate from the documented daily features. [7], [10]

Buyer questions
Before you buy
Should I expect the manufacturer's runtime or the review result?
Use both as conditional reference points. Sony lists 35 hours with ANC or Ambient Sound and 50 hours with both off. GSMArena measured 47.15 hours in an AAC/ANC-on run, but did not disclose all conditions needed for a standardized comparison. Your settings and use still matter. [5], [8]
Compatibility
Can the cable rescue listening when the battery is empty?
Yes, passive analogue listening is supported, but ANC is unavailable with power off. The cited listening review found a different tonal balance in passive mode. USB-C is charging-only, and charging itself prevents operation. [4], [6], [10]
Does the supplied cable carry the headset microphone for calls?
Sony instructs you to answer on the phone and speak into its microphone while hearing the caller through the headphones. Playback and volume are also operated on the source. Do not assume the supplied cable provides a wired headset-microphone connection. [4]
Setup
Will two connected devices play together?
No. Enable two-device connection in the app, then stop the first music source before starting the second. Sony describes switching and call standby, not mixing simultaneous streams. A third connection displaces one existing connection. [2]
Limitations
Is it suitable for rain or sweat-heavy workouts?
No. Sony states that it is not waterproof and warns against soaking from rain, snow or sweat. Comfortable fit does not change that operating limit. [3]
Care and maintenance
Can I rely on replacing the battery later?
Sony recommends consulting a dealer when battery endurance drops significantly. The available evidence does not establish user replacement, local parts availability or a fixed repair cost. Check the local service route before depending on that plan. [10]

Other facts
| Specification | Value | Source |
|---|---|---|
| Buyer Fit | Headphonecheck found the light, padded and adjustable headset comfortable during longer listening. This is that reviewer's fit experience; the selected black ASIN was not independently identified as the test unit.; HIFI.DE regards the lightweight headset's sound and ANC as useful for ordinary daily listening, provided expectations are realistic rather than flagship-level. Germany | [6], [1] |
| Limitation | Headphonecheck found passive cable playback muffled in the highs and boomy in the mids; switching the electronics on improved its listening impression. The review treats passive mode as a battery-empty fallback, not equivalent sound quality.; Sony says connecting the headset to an outlet or computer for charging prevents operations including power-on, Bluetooth connection and music playback. Do not assume wired playback is available while charging. | [10], [6] |
| Risk | Headphonecheck reported unwanted background noise when the noise-canceling circuit faced direct wind. This was a review observation, not a quantified defect rate or a microphone-call measurement. | [6] |
| Setup Requirement | Use the supplied USB-C cable and a USB AC adaptor capable of at least 0.5 A, or a running computer. Sony recommends a direct connection rather than a USB hub and does not guarantee every adaptor or computer.; With the supplied headphone cable, Sony instructs the user to answer on the phone and speak into the phone's microphone. Adjust volume and playback on the source device because the headset's volume and playback buttons cannot be used. | [10], [4] |
KnowSpec analysis
A flexible everyday headset if its practical limits fit your routine
Consider the WH-CH720N for lightweight wireless listening, app-adjustable sound, ANC and switching between a phone and computer. Its analogue cable offers a battery-empty fallback, but passive sound changes and the supplied cable does not carry the headset microphone. Avoid it for wet exercise, USB-audio requirements or uninterrupted listening during charging. Try the fit and plan how its non-folding shape will travel.
Method: Interpretation of Sony runtime instructions and GSMArena's separately identified battery tests.The battery evidence is encouraging, but not a universal promise
The evidence includes manufacturer runtime limits and an independent AAC test that ran longer with ANC enabled. Keep the protocols separate: the review does not disclose volume or firmware, and its quick-charge run starts from an empty battery. Processing settings and usage conditions still matter. Long endurance also does not remove the need to stop operation while charging.
Method: Official care instructions and source-attributed construction observations, with unknown service facts preserved.Treat active and passive cable use as different modes
Power state changes the documented electrical specifications and available noise control. Passive playback can rescue a flat-battery journey, but the cited reviewer heard a different tonal balance. The phone must provide the microphone during a cable-connected call, and source-side playback controls replace the headset buttons. Decide whether those limits match your actual source and call routine.
Method: Official cable and electrical specifications, qualified by Headphonecheck's passive-mode listening observation.Portability and service need checks beyond the headline features
A light headset can still occupy bag space when it does not fold. The available care instructions also rule out water exposure and direct owners to Sony for a deteriorating built-in battery. They establish a maintenance route, without establishing local replacement stock, repair charges or a support-end commitment.
Method: Synthesis of official operating conditions and attributed independent reviews; no new testing.Visible information gaps
