Quick verdict
Go with ACCENTUM Plus for USB audio and an analog fallback. WH-CH730N is the better fit for a lighter folding travel setup, and it has the same 50-hour standard ANC claim.
Before you buy
Why, and what it costs you
Plan your charging around how long you listen
Listening eight hours a day, Sennheiser ACCENTUM Plus Wireless claims the equivalent of 6.3 days in standard ANC mode, and Sony WH-CH730N claims 6.3 days as well. Leave headroom for real use.
Where this comes from
Formula: claimed ANC runtime / 8 hours per day, with 50 and 50 hours as inputs. It is a planning conversion of separate manufacturer maximums. No endurance was measured.

Sennheiser brings a digital wired option
Day to day
How each one fits your routine
Over USB, ACCENTUM Plus can stand in for both laptop audio devices
At a computer desk without Bluetooth, ACCENTUM Plus is documented to handle both listening and microphone recording over a single USB connection. Select it on its own as the playback device and as the recording device, then check the calling application. That makes it the relevant option for this wired job. Sony’s USB port is for charging only and offers no such route, even though both headphones advertise the same ANC listening duration.
Where this comes from
In Sennheiser’s USB procedure, you charge, play audio and record from the microphone, after first disconnecting existing Bluetooth links. For the Sony model, the cataloged USB connection is meant for charging and not for USB audio.
Leaning back on a pillow can change which controls you want
When stray touches interrupt your listening as you rest, ACCENTUM Plus has a documented way to turn off its touch pad in Smart Control. Do that before you settle into your seat, particularly if you plan to run ANC without actively controlling playback. Pick it if that explicit control lock fits your routine. Do not assume Sony will have the same problem or that either headset will suit a particular pillow.
Where this comes from
Lying down is the example Sennheiser gives for turning off accidental touch input. The manual also advises disabling the touch pad when you use ANC alone on a flight. That is an advantage in configuration and not a measure of comfort.

Differences you will notice
Plan your charging around how long you listen
Listening eight hours a day, Sennheiser ACCENTUM Plus Wireless claims the equivalent of 6.3 days in standard ANC mode, and Sony WH-CH730N claims 6.3 days as well. Leave headroom for real use.
How we worked this out
Formula: claimed ANC runtime / 8 hours per day, with 50 and 50 hours as inputs. It is a planning conversion of separate manufacturer maximums. No endurance was measured.
Weigh what you will wear on your head
Sennheiser ACCENTUM Plus Wireless is 227 grams, Sony WH-CH730N is 207 grams, and the gap is 20 grams. Comfort still comes down to clamp force, fit and padding.
How we worked this out
The absolute weight difference is |227 - 207| grams. Cases and most accessories are not part of manufacturer headset weights.
CH730N is 20 grams lighter and advertises the same ANC hours
Both are rated for up to 50 hours of standard ANC playback, and Sony weighs about 9% less than ACCENTUM Plus.
How we worked this out
Working: 227 - 207 = 20 g and 20 / 227 × 100 = 8.8%. The batteryAncHours value is 50 for both.
Plug in your setup
Which headphones suit the way you listen?
Start with how you listen. Charging over USB is not the same as playing audio over USB, and some headphones need power even on a cable. These answers are placeholders until you apply your own.

Battery figures are maker claims for the stated mode. They do not reflect measured travel time. Volume, codec, calls and battery age all change runtime. Closed earcups can still leak some sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not judge sound quality, mic quality or amplifier power.
Option A
Sennheiser, ACCENTUM Plus Wireless
ACCENTUM Plus Wireless
Upgrading to Plus gets you travel extras, namely an analog input, a cable and a carry case, but no extra advertised runtime. At 227 g it weighs less than Momentum 4 and still has USB audio.

- Battery-free analog playback: Yes
Option B
Sony, WH-CH730N
WH-CH730N
What you gain over the CH720N is simple: a frame that folds, plus a 50-hour ANC claim. The cost is 15 g of extra weight, so the older model remains the better pick when low weight is the priority.

Spec by spec
Where they really differ
| Spec | Sennheiser ACCENTUM Plus Wireless | Sony WH-CH730N | In practice |
|---|---|---|---|
| Headphone weight | 227 g | 207 g | The figure leaves out the case, accessories and cables. |
| Standard ANC battery claim | Up to 50 h | Up to 50 h | Runtime can drop with volume, calls, codec choice and special modes. |
| USB digital audio | Yes | No | Having a charging port does not by itself mean audio is supported. |
| Battery-free analog playback | Yes | Yes | Powered noise cancellation is not part of passive listening. |
| Folds inward | No | Yes | Folding affects the shape you pack in addition to the headphone's weight. |
| Two-device Bluetooth multipoint | Yes | Yes | Automatic switching tied to one brand is a separate feature. |
Trade-offs
What each pick costs you
With Sennheiser ACCENTUM Plus Wireless
- Its frame swivels flat and does not fold inward.
With Sony WH-CH730N
- LC3 is supported but LDAC is not, and LC3 only works with a compatible source.
Decision guide
How to decide
Pick ACCENTUM Plus for USB audio and an analog fallback. Pick WH-CH730N for a lighter folding travel setup. Both share the 50-hour standard ANC claim.
Sennheiser brings a digital wired option
USB audio works on ACCENTUM Plus and not on Sony CH730N. An analog cable route exists on both, so check whether your source has USB or a headphone socket.
Sony wins on space and weight
At 207 grams, CH730N folds inward. ACCENTUM Plus weighs 227 grams and does not fold inward, even though the 50-hour ANC claim is the same.
A matching battery claim is not a sound-quality tie
Fifty hours is a manufacturer maximum set under each brand's own test conditions. Fit, seal and noise-control performance need separate evaluation and cannot be worked out from runtime.
