Features
What it does well.
Key features
Role. a USB-powered Bluetooth 5.4 car audio receiver with a built-in microphone, independent music/call controls, switchable coloured light and braided USB-A/3.5mm cable.
Audio path. A phone, tablet or computer sends Bluetooth audio to SKU 35002. The receiver outputs it to a 3.5mm AUX input while USB-A supplies operating power. It does not transmit car/TV audio to Bluetooth headphones.
Codec boundary. No codec list is published. Do not infer AAC, aptX, LDAC, LC3 or lossless Bluetooth from the Bluetooth 5.4 version or high-fidelity wording.
Power design. No internal battery. The adapter operates whenever its USB-A lead receives suitable power. USB-A is the continuous power lead, not a charging or stereo data port. The separate 3.5mm plug carries audio.
Audio direction and connector roles
A phone, tablet or computer sends Bluetooth audio to SKU 35002. The receiver outputs it to a 3.5mm AUX input while USB-A supplies operating power. It does not transmit car/TV audio to Bluetooth headphones.
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. No codec list is published. Do not infer AAC, aptX, LDAC, LC3 or lossless Bluetooth from the Bluetooth 5.4 version or high-fidelity wording.
Latency. UGREEN uses comparative lower-latency language but publishes no millisecond value. Do not sell it as delay-free.
Microphone and calls. A built-in microphone supports hands-free phone calls. Microphone processing is intended to improve call clarity, not provide listener ANC or erase all road noise.
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.
Use scenarios
Scenario 1. Full-button music control in an older car.
Scenario 2. Hands-free calls with the control pad mounted within reach.
Scenario 3. Shared-car use with two paired phones.
Scenario 4. Switching the coloured light off for a darker cabin.
Scenario 5. Home powered-speaker reception through AUX and USB power.
Setup and usability guidance
Usability rule: establish one clean path first. Add a second source, listener, output or peripheral only after the first works reliably.
Controls. Independent buttons support volume, previous/next track, play/pause, answer/end and redial as documented. media also shows the coloured light can be switched off with a five-second hold.
Second-device behaviour. Two source devices can stay connected. Only one programme/call is active at a time; pause one before using the other.
Recovery. Unplug power, forget the receiver on both phones, reconnect and pair one phone again. Re-add the second phone after confirming audio and call controls.
Step 1: Connect USB-A power and 3.5mm AUX while parked.
Step 2: Select AUX and keep the stereo volume low.
Step 3: Open Bluetooth settings and select the UGREEN receiver.
Step 4: Test music, buttons and a call before driving.
Step 5: Pair a second phone only after the first is stable; use the five-second light control if desired.
Compatible devices and systems
Class: Bluetooth phones, tablets and computers as sources; car stereos, wired amplifiers and powered speakers with 3.5mm AUX input plus a suitable USB-A power source.
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
Receives Bluetooth audio from a compatible source.
Outputs analogue audio to the stated 3.5mm and/or RCA line input.
Supports only the call, control and source-count behaviour documented for this revision.
Reconnects to a saved compatible source when powered and available.
Modernises existing audio equipment without replacing its amplifier or speakers.
What this product does not do
receiver only; no internal battery, Bluetooth-headphone transmission, optical/RCA output, codec list, voice-assistant launch promise, USB data audio or water rating.
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 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.
Battery, charging and realistic runtime
Battery/power: No internal battery. The adapter operates whenever its USB-A lead receives suitable power.
Charging/connection: USB-A is the continuous power lead, not a charging or stereo data port. The separate 3.5mm plug carries audio.
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 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: This product does not has a 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. A built-in microphone supports hands-free phone calls. Microphone processing is intended to improve call clarity, not provide listener ANC or erase all road noise. 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.
Reset path. Unplug power, forget the receiver on both phones, reconnect and pair one phone again. Re-add the second phone after confirming audio and call controls.
