Features
What it does well.
Key features
Role. a USB-A Bluetooth host adapter that adds Bluetooth audio, controller, keyboard, mouse, phone and other supported peripheral connections to a compatible Windows computer.
Audio path. The adapter makes a Windows PC the Bluetooth host. The PC can send audio to headphones/speakers, receive supported headset microphone audio and exchange supported peripheral/data traffic. It is not a stand-alone AUX transmitter or car receiver.
Codec boundary. No audio codec list is asserted. Windows and the connected headset negotiate supported Bluetooth audio profiles/codecs; aptX, LDAC and LC3 are not promised by SKU 35058.
Power design. No battery. The adapter is powered continuously by the computer USB-A port. USB-A/USB 2.0 host connection supplies power and data. Do not connect it to a charger expecting stand-alone Bluetooth operation.
Audio direction and connector roles
The adapter makes a Windows PC the Bluetooth host. The PC can send audio to headphones/speakers, receive supported headset microphone audio and exchange supported peripheral/data traffic. It is not a stand-alone AUX transmitter or car receiver.
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 audio codec list is asserted. Windows and the connected headset negotiate supported Bluetooth audio profiles/codecs; aptX, LDAC and LC3 are not promised by SKU 35058.
Latency.
Microphone and calls. A compatible Bluetooth headset microphone can work when Windows, the headset and the call application expose a headset profile and select the correct input. Console voice chat is not supported by plugging this dongle into a console.
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 a desktop PC without a radio.
Scenario 2. Replacing a disabled or unstable built-in Windows Bluetooth adapter.
Scenario 3. Connecting one headset plus different peripheral types.
Scenario 4. Using compatible game controllers with a Windows PC, not a console.
Scenario 5. Transferring supported data between a Windows PC and phone.
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. Pair, remove and troubleshoot devices through Windows Bluetooth settings and Device Manager. Disable the computer’s built-in Bluetooth before using CM748 to prevent driver/radio conflicts.
Second-device behaviour. Up to five different device types can be connected. Only one Bluetooth audio output should be expected to play at a time; five connections do not mean five audio streams.
Recovery. Remove failed pairings in Windows, reboot the PC, reinsert CM748 and pair again. If a built-in Intel/Realtek Bluetooth radio re-enables, disable it before retesting.
Step 1: Disable any built-in Bluetooth adapter in Device Manager.
Step 2: Insert CM748 into a direct USB-A port on the Windows PC.
Step 3: Allow Windows 11/10/8.1 to install its support; Windows 7 requires the official driver.
Step 4: Open Bluetooth settings, put one peripheral in pairing mode and add it.
Step 5: Test one device first, then add additional different device types up to the documented limit.
Compatible devices and systems
Class: Windows 11, 10 and 8.1 plug-and-play; Windows 7 with the UGREEN driver. Bluetooth headphones, speakers, headset, keyboard, mouse, phone, printer and compatible controllers are representative device classes.
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, iOS/Android host mode, car stereo, TV or direct PS/Xbox/Switch-console use; not an AUX adapter; no codec, console voice-chat or five-audio-stream promise.
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. The adapter is powered continuously by the computer USB-A port.
Charging/connection: USB-A/USB 2.0 host connection supplies power and data. Do not connect it to a charger expecting stand-alone Bluetooth operation.
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. A compatible Bluetooth headset microphone can work when Windows, the headset and the call application expose a headset profile and select the correct input. Console voice chat is not supported by plugging this dongle into a console. 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 failed pairings in Windows, reboot the PC, reinsert CM748 and pair again. If a built-in Intel/Realtek Bluetooth radio re-enables, disable it before retesting.
