UGREEN 55545 Bluetooth 6.0 LDAC AUX/RCA Receiver, 15H
Overview
Bluetooth 6.0SKU 55545Bluetooth Hi-Res ReceiverReceiver only
UGREEN 55545 receiver with 3.5mm and RCA cables
Key features
Role
a rechargeable Bluetooth 6.0 receiver for streaming from a phone, tablet or computer to an existing stereo, amplifier, wired headset or powered speaker through 3.5mm or RCA.
Audio path
A compatible Bluetooth source sends audio to SKU 55545. The unit decodes it and provides analogue output through 3.5mm or red/white RCA. It is not a transmitter for Bluetooth headphones.
Codec boundary
LDAC, AAC and SBC are exact. LDAC up to 24-bit/96kHz requires a source that supports and enables LDAC; iPhone uses AAC or SBC. aptX is explicitly absent from media.
Power design
Audio direction and connector roles
A compatible Bluetooth source sends audio to SKU 55545. The unit decodes it and provides analogue output through 3.5mm or red/white RCA. It is not a transmitter for 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.
Supported source and powered-audio destination roles
Sound, codecs, calls and latency
Codecs
LDAC, AAC and SBC are exact. LDAC up to 24-bit/96kHz requires a source that supports and enables LDAC; iPhone uses AAC or SBC. aptX is explicitly absent from media.
Latency
UGREEN describes lower latency but publishes no millisecond value or dedicated gaming codec. Do not market it as delay-free.
Microphone and calls
No built-in microphone or hands-free call path is listed. A wired headset connected to the output receives audio only; its boom microphone is not returned to the phone.
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
LDAC music from a compatible Android player to a home amplifier.
Scenario 2
AAC playback from iPhone to powered speakers.
Scenario 3
Sharing one stereo between two paired source phones.
Scenario 4
Long listening sessions while connected to USB-C power.
Scenario 5
Adding Bluetooth reception to legacy 3.5mm or RCA audio gear.
Home-speaker listening scenario
Setup and usability guidance
Step 1: Charge the receiver with USB-C.
Step 2: Connect 3.5mm or RCA output to a line/AUX input and select it.
Step 3: Pair the first phone from Bluetooth settings and test at low volume.
Step 4: Pair a second phone only after the first connection is stable.
Step 5: For LDAC, enable it on a compatible Android/source device and confirm the active codec in source settings.
Usability rule: establish one clean path first. Add a second source, listener, output or peripheral only after the first works reliably.
Controls
The multifunction button manages power and pairing. Source selection is practical rather than mixed: pause one phone, then start the other.
Second-device behaviour
Two phones can stay paired, but only one can play at a time. Pause the active source before starting audio on the other.
Recovery
If a saved phone will not reconnect, pause/disconnect the other phone, forget the receiver on both sources, power-cycle it and pair the desired source first.
Dual-source pairing behaviour
Compatible devices and systems
Class: Bluetooth-audio phones, tablets and computers as sources; home stereos, amplifiers, powered speakers, car AUX systems and wired headphones with 3.5mm or RCA line-level connectivity.
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.
Published long-distance connection example
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 Bluetooth-headphone transmission, aptX, microphone/calls, audio mixing, optical/coaxial audio or water-resistance rating; LDAC is not available from every source.
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
Charging/connection: USB-C charging, about 2 hours to full, and use while charging. A charger is not listed in the package.
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
No built-in microphone or hands-free call path is listed. A wired headset connected to the output receives audio only; its boom microphone is not returned to the phone. 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
If a saved phone will not reconnect, pause/disconnect the other phone, forget the receiver on both sources, power-cycle it and pair the desired source first.
