Quick verdict: buy for convenience, not complete silence
The Sony WH-CH730N are worth considering if you want foldable, lightweight headphones for commuting, music and occasional calls. Their strongest case is everyday convenience and Sony’s longer battery claims. The biggest compromise is noise cancellation: nearby voices can still get through.
Choose them if portability matters and you are willing to adjust the sound in Sony’s app. Skip them if your main goal is shutting out office conversations. A discounted WH-CH720N is the closest value alternative; existing owners need not rush to upgrade.

Sound, ANC and calls: three different jobs
ANC and call-microphone processing serve different purposes; this is a conceptual diagram, not an attenuation test.
Independent findings: SoundGuys’ Christian Thomas found that the ANC reduced surrounding noise but struggled with some voice-range sounds and train squeal. What Hi-Fi’s reviewers also heard office conversations through it. Expect reduced distraction, rather than a silent room.
Both publications described the default sound as bass-heavy or muffled. What Hi-Fi was more enthusiastic after changing the EQ; SoundGuys remained more reserved about the tuning. Start with the Clear preset in Sound Connect, then adjust to taste rather than assuming the factory setting is ideal.
SoundGuys’ microphone samples showed useful background-noise rejection. That concerns what the caller hears; it does not mean the ANC blocks those sounds for you. For frequent meetings, try the headphones with your actual laptop and calling app while you can still return them.
Strengths: folding design; physical controls; two-device connectivity; longer claimed music endurance than the CH720N.
Compromises: voices remain audible; default tuning benefits from adjustment; no USB-C audio; no IP rating for rain or workouts.
Battery life: 75 hours is not the calling figure
Sony maximum specifications: 50/75 hours for music, 35/40 for calls. These are not measured Decively results.
Sony’s maximum claims: 50 hours of music with ANC on, or 75 with it off. Continuous calls have separate limits: 35 and 40 hours respectively. Volume, settings and usage affect endurance; a day split between meetings and music cannot be calculated from the 75-hour headline alone.
Independent evidence: SoundGuys had not completed its battery rundown in the review checked on October 8, 2026. We therefore cannot present 50 hours as a measured result. Sony’s app includes Battery Care, but there is not yet enough long-term evidence to promise a particular lifespan.
At approximately 207 g, these are light over-ear headphones, with folding earcups and button controls. SoundGuys found low clamping pressure comfortable, although getting a consistent seal could take adjustment. Check the fit with glasses if you wear them; fit affects both comfort and isolation.
Connectivity: useful for a phone and laptop
Multipoint switches between sources. The 3.5 mm cable carries audio; USB-C charges the headphones.
Bluetooth multipoint lets the CH730N connect to two devices, so you can move between a computer and phone without re-pairing each time. It is source switching, not mixing two audio streams. Sound Connect is available for Android and iPhone.
Sony lists SBC and AAC for Classic Audio, and LC3 for LE Audio; LDAC is not listed. LE Audio requires a compatible device and the relevant connection setting. Sony’s guide notes that some features, including its voice-assistant setting, are unavailable during an LE Audio connection.
For wired listening there is a 3.5 mm connection and supplied headphone cable, including passive playback. SoundGuys confirms that USB-C is for charging rather than audio. These are Bluetooth headphones, not a USB conferencing headset with a dedicated wireless dongle.
WH-CH730N vs WH-CH720N: what changes?
| Buying point | CH730N | CH720N |
|---|---|---|
| Folds for travel | Yes | No |
| Music, ANC on* | Up to 50 hours | Up to 35 hours |
| Music, ANC off* | Up to 75 hours | Up to 50 hours |
| Weight | Approx. 207 g | Approx. 192 g |
| Bluetooth codecs | SBC, AAC, LC3** | SBC, AAC |
*Manufacturer maximum claims, not Decively test results. **LC3 requires a compatible LE Audio connection. Other settings affect actual playback time.
The upgrade buys folding portability and a higher claimed music-playback ceiling. It does not establish a dramatic ANC improvement. Keep a working CH720N unless those changes solve a real problem. For a new purchase, a substantial CH720N discount may outweigh the newer model’s convenience.
If stronger noise cancellation is your priority, compare the premium options in our wireless-headphones buying guide before choosing on battery life alone.
Final verdict: check the price gap and your priorities
Buy the CH730N for a compact bag-friendly design, simple controls and everyday listening with some background-noise reduction. Consider the CH720N when it costs meaningfully less. Look higher in the range if suppressing conversations matters more than spending less.
This model launched in September 2026, so durability and battery aging remain open questions. Our verdict is a synthesis of official documentation and attributed independent reviews; Decively has not physically tested these headphones.

Two quick buying questions
Can you use the Sony WH-CH730N with an iPhone?
Yes, through Bluetooth. Sony’s Sound Connect app is also available on iOS. Do not assume every LE Audio function is supported by your particular phone.
Should CH720N owners upgrade?
Usually only if folding earcups or longer claimed music endurance would make a noticeable difference. The new model alone is not evidence of a major noise-cancelling upgrade.
