Key features

Exact role

a rechargeable 3.5mm Bluetooth audio adapter that transmits wired audio to Bluetooth listeners in TX mode and receives phone audio for a wired AUX system in RX mode.

Audio path

TX mode takes analogue audio from an airplane seat, TV, computer or other 3.5mm output and sends it to Bluetooth headphones/speakers. RX mode receives Bluetooth audio from a phone/tablet and outputs it through the integrated 3.5mm plug to a car, amplifier or powered speaker.

Codec boundary

Exact documentation lists TX: SBC. RX lists SBC and AAC. aptX, aptX Adaptive, LDAC and LC3 are not claimed.

Power design

Up to 28 hours in TX mode and up to 20 hours in RX mode under UGREEN test conditions. Mode, volume, calls, temperature, battery age and RF environment affect runtime. USB-C rechargeable, with a 300mAh, 3.7V / 1.11Wh lithium battery listed. Follow airline rules for portable lithium devices and do not charge if wet or damaged.

Audio direction and connector roles

TX mode takes analogue audio from an airplane seat, TV, computer or other 3.5mm output and sends it to Bluetooth headphones/speakers. RX mode receives Bluetooth audio from a phone/tablet and outputs it through the integrated 3.5mm plug to a car, amplifier or powered speaker.

Connector rule: a source/output must feed a destination/input. USB power, USB host data, analogue AUX and Bluetooth radio roles are separate even when one enclosure handles several of them.

Start safely: set the correct mode, select the target input and lower every volume control before testing.

Sound, codecs, calls and latency

Codecs

Exact documentation lists TX: SBC. RX lists SBC and AAC. aptX, aptX Adaptive, LDAC and LC3 are not claimed.

Latency

No exact millisecond result is verified. SBC/AAC do not establish delay-free television or gaming use; source processing and listening-device buffers also matter.

Microphone and calls

The built-in microphone supports calls in RX mode. TX mode sends programme audio only and does not return a Bluetooth headset microphone to an airplane, TV or computer.

Real-world fidelity

Source file, negotiated codec, radio conditions, analogue cable, amplifier and speakers/headphones all affect the result. A newer Bluetooth number is not automatically higher sound quality.

Setup and usability guidance

  1. Step 1: Charge CM672 and set TX or RX before pairing.
  2. Step 2: In TX, plug into a headphone/line output; in RX, plug into a line/AUX input.
  3. Step 3: Put the first Bluetooth endpoint in pairing mode and keep other saved devices away.
  4. Step 4: Confirm stable audio at low volume before adding a second endpoint.
  5. Step 5: For twin-prong aircraft sockets, use the supplied flight adapter only where permitted.

Usability rule: establish one clean path first. Add a second source, listener, output or peripheral only after the first works reliably.

Controls

A TX/RX switch defines the wired-port role; the multifunction control handles power/pairing. Set the mode before connecting and pair one endpoint before adding the second.

Second-device behaviour

Up to two Bluetooth endpoints are listed in both TX and RX modes. TX shares one source programme with two listeners; RX provides convenient two-source connection, not mixed simultaneous programmes.

Recovery

Forget CM672 on source devices or clear saved listener pairings as applicable, power-cycle the adapter in the desired mode and follow the exact CM672 reset timing.

Compatible devices and systems

Verified class: 3.5mm headphone/line sources such as airplane entertainment, TVs and computers in TX; Bluetooth phones/tablets/computers plus car AUX, powered speakers and amplifiers in RX.

  • Match the operating-system/audio profile and connector role, not only the Bluetooth logo.
  • Confirm whether you need programme audio, microphone return, peripheral data or file transfer; these use different profiles.
  • For AUX/RCA products, confirm the destination is a line-level input and already has its own amplifier.
  • For PC adapters, verify driver requirements and disable a competing built-in Bluetooth radio.
  • For two-way products, confirm that the chosen TX or RX mode matches the wired device.

What this product does

  • Switches a 3.5mm connection between transmitter input and receiver output roles.
  • Pairs the exact number of endpoints documented for this SKU.
  • Runs from its internal rechargeable battery for portable use.
  • Reconnects to saved compatible endpoints when the selected mode matches.
  • Carries programme audio within the exact codec and call boundaries stated above.

What this product does not do

  • no aptX/LDAC, optical audio, USB data audio, guaranteed lip-sync, TX microphone return, passive-speaker amplification or water rating; aircraft use remains subject to crew instructions.
  • Does not guarantee uninterrupted wireless service through metal, walls, crowds or heavy 2.4GHz interference.
  • Does not repair a damaged source, USB port, AUX socket, amplifier or speaker.
  • Does not make a connector compatible merely because it fits physically.
  • Does not prove ANC, aptX, LDAC, multipoint or microphone return from the Bluetooth version number alone.

What to do

Check the label

Confirm SKU, model and stored revision on the product or box before relying on a specification.

Begin with one endpoint

Pair and test one path before adding any supported second device or output.

Lower volume first

Protect hearing and speakers when changing mode, output, codec, call profile or device.

Keep connections dry

Inspect USB and audio plugs, remove debris without metal tools and dry completely before power.

Use official drivers/manuals

Use the exact CM/BT model instructions; related UGREEN revisions can use different buttons and radios.

Pause before switching

When two sources are connected, pause the current programme before starting the other.

What not to do

Do not infer features

Bluetooth 5.x/6.0 alone does not establish codec, ANC, microphone, multipoint or delay.

Do not force plugs

Stop if a connector does not align; check port type, direction, damage and case clearance.

Do not use speaker-level output

AUX/RCA receiver inputs are line-level; passive speakers still need an amplifier.

Do not pair while moving

Configure car and aircraft audio before movement and follow local/crew instructions.

Do not charge damaged cells

Stop for swelling, leakage, odour or abnormal heat and seek proper battery disposal.

Do not borrow reset timing

Sibling models and revisions often use different hold durations and indicators.

Battery, charging and realistic runtime

Battery/power: Up to 28 hours in TX mode and up to 20 hours in RX mode under UGREEN test conditions. Mode, volume, calls, temperature, battery age and RF environment affect runtime.

Charging/connection: USB-C rechargeable, with a 300mAh, 3.7V / 1.11Wh lithium battery listed. Follow airline rules for portable lithium devices and do not charge if wet or damaged.

  • Published runtime is normally a controlled maximum; volume, calls, codec, temperature, range and battery age can shorten it.
  • USB-powered models have no reserve runtime and stop when vehicle/computer power stops.
  • Use compliant, undamaged power sources and disconnect any product that becomes unusually hot.
  • Do not leave rechargeable products empty for months; follow the exact manual for long-term storage.

Warnings and limitations

  • Hearing: begin at low volume, limit exposure and stop if you notice discomfort or ringing. Bluetooth features and noise processing are not hearing protection.
  • Battery: never crush, puncture, short, burn or charge a swollen, leaking, wet or unusually hot rechargeable product. USB-powered models still require a sound, compliant 5V source.
  • Aircraft: follow crew instructions, use only permitted headphone outputs and keep wireless devices off whenever directed. Carry lithium products in accordance with airline rules.
  • Driving: pair, mount, select sources and set volume while parked. Hands-free calling does not remove attention or legal responsibilities.
  • Water: no exact product here has a verified IP rating. Keep adapters, plugs and charging ports dry; never connect power while damp.
  • Heat and storage: do not leave the product on a hot dashboard, near a heater or in direct sun. Keep small adapters and cables away from children and pets.
  • Audio ports: connect only to the stated headphone/AUX line-level role. Never connect a 3.5mm/RCA port to mains, passive-speaker output or an unknown industrial signal.

Troubleshooting and reset

No pairing

Bring devices close, verify power/mode, disconnect competing saved devices and pair one endpoint first.

Connected but silent

Check source playback, OS output, TX/RX direction, AUX input selection, cable seating and both volume controls.

Audio but no microphone

The built-in microphone supports calls in RX mode. TX mode sends programme audio only and does not return a Bluetooth headset microphone to an airplane, TV or computer. Confirm the call app input and permissions only where a microphone path is documented.

Drop-outs

Reduce distance and metal/body obstruction, move from crowded 2.4GHz radios and test one connection at a time.

Delay

Compare with a wired path; no unstated codec or Bluetooth version can remove all source and endpoint buffering.

Exact reset path

Forget CM672 on source devices or clear saved listener pairings as applicable, power-cycle the adapter in the desired mode and follow the exact CM672 reset timing.
