Features
What it does well.
Key features
Role. a compact USB-A Bluetooth host adapter for adding wireless audio, phone data and compatible peripheral connections to a Windows desktop or laptop.
Audio path. CM390 makes the Windows PC the Bluetooth host. The PC can send audio to headphones/speakers, receive supported headset microphone audio and connect peripherals/phones. It is not a stand-alone transmitter for a TV or AUX receiver for a car.
Codec boundary.
Power design. No battery. USB-A supplies host data and operating power from the PC. Plug into a computer USB-A port. A wall charger supplies power but no Windows host, so stand-alone Bluetooth operation will not work.
Audio direction and connector roles
CM390 makes the Windows PC the Bluetooth host. The PC can send audio to headphones/speakers, receive supported headset microphone audio and connect peripherals/phones. It is not a stand-alone transmitter for a TV or AUX receiver for a car.
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.
Latency. No millisecond figure is verified. EDR/BLE and Bluetooth 5.0 do not guarantee competitive-game timing or real-time instrument monitoring.
Microphone and calls. Compatible Bluetooth headsets may provide microphone input when Windows and the application select a headset profile. This does not make the dongle a direct-console voice-chat adapter.
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. Adding Bluetooth to an older Windows desktop.
Scenario 2. Connecting a headset and different office peripherals.
Scenario 4. Using a compatible controller on a Windows PC.
Scenario 5. Obtaining up to 20m open-space coverage in suitable conditions.
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. Pairing and removal are handled in Windows Bluetooth settings. Disable existing built-in Bluetooth in Device Manager before installing/reinserting CM390.
Second-device behaviour. Up to five different device classes are listed. This is not five simultaneous audio streams; expect one active Bluetooth audio output and test each new device type separately.
Recovery. Remove the failed Windows pairing, reboot, reinsert CM390 and pair again. Confirm the built-in radio remains disabled and use the CM390 driver where required.
Step 1: Disable the PC’s built-in Bluetooth radio.
Step 2: Insert CM390 into a direct USB-A port.
Step 3: Use Windows 11/10/8.1 support; install the official driver for Windows 7.
Step 4: Put one endpoint in pairing mode and add it through Windows.
Step 5: Test the first connection, then add other different device classes up to the listed limit.
Compatible devices and systems
Class: Windows 11, 10 and 8.1; Windows 7 with official driver. Representative devices include Bluetooth headphones/headset, speaker, phone, keyboard, mouse and compatible game controller.
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
Adds a Bluetooth host radio to a supported Windows computer.
Connects supported audio devices and several different peripheral classes.
Uses Windows controls and profiles for audio, microphones, HID and supported phone links.
Receives USB power and host data directly from the PC.
Works only within the documented operating-system and driver boundaries.
What this product does not do
not macOS, Linux, car stereo, TV, stand-alone AUX use or direct PlayStation/Xbox/Switch console connection; no promised codec, five-audio-stream output or guaranteed console voice chat.
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 battery. USB-A supplies host data and operating power from the PC.
Charging/connection: Plug into a computer USB-A port. A wall charger supplies power but no Windows host, so stand-alone Bluetooth operation will not work.
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.
Computer safety: remove the adapter before transporting a laptop where the exposed dongle could be struck, and do not force it into damaged or obstructed USB ports.
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. Compatible Bluetooth headsets may provide microphone input when Windows and the application select a headset profile. This does not make the dongle a direct-console voice-chat adapter. 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. Remove the failed Windows pairing, reboot, reinsert CM390 and pair again. Confirm the built-in radio remains disabled and use the CM390 driver where required.
