Sony ULT WEAR vs WH-CH720N: Which Codec and Travel Setup Fits You?

Choose ULT WEAR if your Bluetooth source supports LDAC and you will enable/verify the required setting, or you value its documented fold-into-supplied-case routine and physical ULT1/ULT2 toggle. Choose WH-CH720N when SBC/AAC meets your source needs and you do not need those ULT-specific features. Both provide app-based EQ adjustment. Specs and handling features do not establish a sound or ANC winner.

The buying question

Does your source device support LDAC, and do you value the ULT WEAR fold-and-supplied-case routine or its physical ULT bass-mode button?

ULT WEAR adds LDAC support when the source supports it and Sony settings are configured; its guide also documents folding it into the supplied case and using a physical ULT1/ULT2 button. WH-CH720N lists SBC/AAC and, per What Hi-Fi, does not fold or include a designated case. Both models document app-based EQ controls, so app tuning is not an exclusive reason to choose either. These distinctions do not establish a sound or ANC winner.

Quick verdict

Choose Sony WH-CH720N Wireless Noise Canceling Over-Ear Headphones, Black (WH-CH720N/B) if

  • Your playback source uses SBC/AAC and LDAC support would not solve a requirement.
  • You do not need the ULT WEAR fold-and-case routine or physical ULT mode button; both apps provide sound adjustments.
When the recommendation changes
  • Your playback device's codec support or current Bluetooth settings differ from the Sony LDAC instructions; verify the codec shown after pairing.
  • You need a supplied carrying case or a particular packed size; check the exact retail package and your bag rather than assuming a folded-size comparison.
  • You need a matched listening or ANC performance result; this comparison does not test either model.

The differences that matter

Codec Host Requirements

Sony ULT WEAR Over-Ear Noise Canceling Wireless Headphones, Black (WH-ULT900N / WHULT900NB.UC)

WH-ULT900N supports SBC, AAC, and LDAC. LDAC use still depends on an LDAC-capable Bluetooth playback device and selecting Priority on Sound Quality in Sony | Sound Connect; the actual codec can be checked in the app.[1, 3, 8]

Sony WH-CH720N Wireless Noise Canceling Over-Ear Headphones, Black (WH-CH720N/B)

WH-CH720N lists SBC and AAC; Sony's WH-CH720N support specification does not list LDAC. When a source only supports SBC/AAC, codec compatibility alone supplies no LDAC-specific reason to select ULT WEAR; consider the other documented workflow needs.[2, 9]

What this changes: If you want LDAC, check the source device first and confirm the negotiated codec in Sound Connect. If your source only supports SBC/AAC, both models list those baseline formats, so decide on other needs rather than assuming the ULT WEAR will change the codec path.[3, 1, 2]

The better fit depends on your priorities

Folding Control Workflow

Sony ULT WEAR Over-Ear Noise Canceling Wireless Headphones, Black (WH-ULT900N / WHULT900NB.UC)

ULT WEAR's guide describes flattening both earcups, folding one unit toward the headband, and storing it in the supplied case. Its ULT button cycles ULT1/ULT2/OFF and retains the last setting. Sony also documents app-based Equalizer/Bass Control for this model; the physical button is an additional way to select ULT modes.[4, 6, 8, 10]

Sony WH-CH720N Wireless Noise Canceling Over-Ear Headphones, Black (WH-CH720N/B)

What Hi-Fi's WH-CH720N review reports that it does not fold away and has no designated carry case. Sony documents Equalizer/CLEAR BASS customization through Headphones Connect. This is an app-based sound adjustment routine, not an advantage over ULT WEAR's app controls.[5, 7, 9]

What this changes: For storage, ULT WEAR documents folding the cups into its supplied case; What Hi-Fi reports that WH-CH720N does not fold and lacks a designated case. For bass adjustments, Sony documents a physical ULT1/ULT2/OFF toggle plus app adjustment on ULT WEAR, while WH-CH720N's documented EQ/CLEAR BASS path is app-based. Both also have app-based tuning, so choose by whether you value the ULT physical toggle and storage routine rather than treating the app as a unique advantage.[4, 6, 10, 5, 7, 8, 9]

The better fit depends on your priorities

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Do not pay a premium for LDAC unless the playback device supports it and that codec path matters to you; compare current checkout offers separately.

Check current checkout prices, seller terms and availability. Price history was not assessed.

Limitations

  • This is a feature and handling comparison from published documentation and one independent WH-CH720N review, not matched listening, codec-bitrate, ANC, comfort, or sound-quality testing.
  • LDAC playback requires support at both ends of the Bluetooth connection and Sony's specified setup; compatibility and negotiated codec depend on the actual playback device and settings.
  • Sony's published WH-CH720N box list includes a connection cable and USB cable; What Hi-Fi reports it does not fold or include a designated case. No packed dimensions or third-party case fit were tested.
  • Current offers, sellers and package contents can change; confirm the exact US black SKU and included accessories at checkout.

Questions shoppers ask

Does the ULT WEAR always play over LDAC?

No. Sony says the playback device must also support LDAC. Sony recommends setting Sound Connect to Prioritize Sound Quality and checking the displayed codec after pairing; device-specific codec settings may also be needed. If your source cannot send LDAC, the ULT WEAR's LDAC support alone does not create that connection.

Which one is easier to pack away?

Sony's ULT WEAR guide says to rotate the cups flat, fold one toward the headband, and store it in the supplied case. What Hi-Fi reports the WH-CH720N does not fold away and has no designated case. No packed-volume or third-party case-fit test was performed.

Can I adjust bass on both?

Yes. Sony documents app-based sound adjustment for both models. ULT WEAR also has a physical ULT button that cycles ULT1/ULT2/OFF; WH-CH720N's documented Equalizer/CLEAR BASS controls are in Headphones Connect. These are control workflows, not a measured sound comparison.

Methodology and sources

Compared the US Black Sony ULT WEAR and WH-CH720N models using Sony model specifications/help guides for codecs, playback setup, app controls, and fold/case steps, with What Hi-Fi’s exact-model WH-CH720N review for its non-folding/no-case observation. Both models document app-based sound adjustment; only ULT WEAR has the documented physical ULT1/ULT2/OFF control. No acoustic or noise-cancellation tests were conducted.

Automated tools assisted with source organization and drafting; claims report documented specifications, settings and package/handling observations rather than hands-on results.
