UGREEN CM721 vs 80154: Choose by Charging and Playback Needs

Choose the CM721 if you need wired listening and charging through one USB-C port at once. Choose the 80154 for audio-only use if its stated 24-bit/96-kHz ceiling fits your playback chain. The CM721 lists a higher 32-bit/384-kHz ceiling, but that is not evidence of audible superiority.

The buying question

Should you choose the CM721 (25837) or 80154 for wired listening, charging during playback, and the audio formats your playback chain can use?

The CM721 adds a USB-C charging input and advertises a higher decode ceiling; the 80154 is an audio-only adapter with a lower advertised ceiling. Neither specification establishes better audible sound.

Quick verdict

When to skip: Your device lacks USB-C digital audio support, or you need USB data through the charging input on the CM721.
When the recommendation changes
  • If you will not charge while listening and your files, app and host stay within 24-bit/96-kHz, the format numbers alone do not establish a practical reason to choose the CM721.
  • If simultaneous charging is essential, the 80154 has no charging port; verify that your host supports USB-C digital audio and that your charger/device support the desired pass-through power.

The differences that matter

Simultaneous Charging And Audio Port Workflow

UGREEN CM721 (25837) USB-C audio and charging adapter

UGREEN 25837 (CM721) has a USB-C charging input alongside 3.5 mm audio; up to 60 W pass-through is listed, with power-only USB-C input and device/charger conditions.[1]

UGREEN 80154 USB-C to 3.5 mm audio adapter

UGREEN 80154 has 3.5 mm audio and no charging input; the manufacturer directs buyers who need charging during listening to model 25837.[2]

What this changes: The CM721 is the documented fit when both wired audio and charging need to use the device’s USB-C port at once; 80154 is for audio-only use.[1, 2]

The better fit depends on your priorities

Advertised Decode Format Ceiling For Supported Playback Chain

UGREEN CM721 (25837) USB-C audio and charging adapter

Manufacturer-stated DAC decode ceiling: up to 32-bit/384-kHz.[1]

UGREEN 80154 USB-C to 3.5 mm audio adapter

Manufacturer-stated DAC decode ceiling: up to 24-bit/96-kHz.[2]

What this changes: A buyer should consider this only when the complete source/app/host playback chain uses formats above the 80154 ceiling; the figures do not prove a sound-quality difference.[1, 2]

The better fit depends on your priorities

Best fit: UGREEN CM721 (25837) USB-C audio and charging adapter

Based on listed features, not comparative testing.

The CM721 page documents a separate USB-C charging input alongside the 3.5 mm audio jack; the 80154 page says it has no charging port. Check host audio support and charger/device power compatibility.

Audio-only listening where a 24-bit/96-kHz stated ceiling is sufficient

The better fit depends on your priorities

The 80154 lists up to 24-bit/96-kHz, while the CM721 lists up to 32-bit/384-kHz. These manufacturer-stated ceilings do not establish audible improvement; choose by the playback chain you actually use.

Value and trade-offs

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

No price comparison is made. Any price difference should be weighed against whether charging during wired listening or the higher stated decode ceiling is useful in your setup.

No purchase-timing recommendation is made because current offers and price history were not assessed.

Limitations

  • The exact-model feature pages used here are from UGREEN India. They identify SKUs 25837/CM721 and 80154, while the US Amazon listings identify the ASINs with the same model and part numbers; regional warranty, package contents or compatibility may differ. Check the exact US listing before ordering.
  • Both format figures are manufacturer-stated maximum decode ceilings. No listening test or measurement establishes audible differences or actual output for a particular host, app, file or headphone.
  • The CM721 page says its USB-C input is for charging only, not data, and that charging depends on the host and charger. The exact USB-C host must support digital audio.
  • Neither adapter was tested hands-on. Current offers and price history were not assessed.

Questions shoppers ask

Can the 80154 charge my device while I listen?

No. UGREEN describes the 80154 as an audio-only adapter with no charging port. The CM721/25837 has a separate USB-C charging input, listed for up to 60 W pass-through, subject to the host and charger.

Does 32-bit/384-kHz mean the CM721 will sound better?

Not by itself. It is the manufacturer’s stated maximum decode format. Your source, app and host must support the format, and these specifications are not a listening comparison.
