MOREGAX Bluetooth 5.3 Audio Receiver & Transmitter Adapter

MOREGAX M18 is a compact Bluetooth 5.3 audio receiver and transmitter that connects TVs, stereos, phones, and headphones for low-latency wireless HiFi sound via USB, RCA, 3.5mm, optical, and coaxial ports.

Whether you want to stream music from a phone to an older home stereo, send TV audio to Bluetooth headphones, or use USB drives and digital outputs, the M18 blends modern wireless connectivity with multiple legacy audio interfaces. The unit’s dual-antenna design extends Bluetooth range, while the upgraded knob, DSP tuning and RGB feedback give tactile control and visual status at a glance.

How does the M18 let me add Bluetooth to my existing stereo or TV?

The M18 works both as a receiver and a transmitter: in receiver mode it accepts Bluetooth from phones or computers and outputs to analogue or digital inputs on amps and TVs; in transmitter mode it sends audio from TVs or players to Bluetooth headphones or speakers. Setup is plug-and-play for most devices and includes automatic proximity reconnection.

• Receiver mode: Bluetooth-in to RCA, 3.5mm, optical or coaxial-out.
• Transmitter mode: optical/coaxial or 3.5mm-in to Bluetooth-out.
• Auto pairing and dual-antenna Bluetooth 5.3 for stable links.
• USB port supports playback from flash drives (file support depends on format).

What controls and sound adjustments are available on the unit?

The front-mounted knob provides power, volume, and intuitive control over the integrated bass and treble adjustments. The M18 includes a high-performance DSP for clearer treble and balanced low end, so you can tailor the tone to your speakers or headphones without using external EQs.

• Rotary knob: power on/off and volume control.
• Dedicated bass and treble knobs for quick tonal tweaks.
• DSP tuning for refined frequency response and clarity.
• RGB status lighting indicates mode and connection state.

Will the Bluetooth range and latency be good enough for TV and outdoor use?

The M18’s dual-antenna and Bluetooth 5.3 implementation extend the usable range: expect up to about 80–110 feet (25–35 m) indoors and up to 160 feet (50 m) line-of-sight outdoors. Low-latency performance depends on the paired headphones or speaker; use compatible aptX/low-latency devices for the best sync with video.

• Indoor range: typically 25–35 meters, varies by obstacles.
• Outdoor line-of-sight range: up to approximately 50 meters.
• Latency: improved with low-latency codecs on both ends.
• Interference factors: walls, Wi-Fi routers and metal objects can reduce range.

Which ports and formats does the MOREGAX M18 support?

The M18 is built for compatibility: it offers 3.5mm AUX, RCA stereo, optical and coaxial I/O, a USB port for flash drives, and a 6.5mm microphone input for karaoke or vocal use. Note that optical/coaxial operations differ by mode—optical coaxial is used in transmitter mode for sending digital audio from a source to Bluetooth devices.

• Analogue: 3.5mm AUX and RCA stereo outputs/inputs.
• Digital: optical and coaxial I/O for TVs and DAC chains.
• USB: playback from flash drives (check file compatibility).
• Microphone jack: 6.5mm input for live singing or announcements.

Who is this for? The MOREGAX M18 suits anyone wanting to modernize legacy audio gear, add wireless headphones to a TV without built-in Bluetooth, or carry a small HiFi-capable adapter for parties, karaoke, and living-room streaming. It’s aimed at home audio enthusiasts, gamers, and content-watchers who need flexible connectivity, tactile controls, and extended wireless range without replacing existing equipment.
