Audio Intelligence

It Listens.
It Reacts.

  • 🎵
    Beat Detection
    The built-in microphone analyzes bass, rhythm, and tempo in real time. LEDs flash, breathe, and dance in perfect sync with your music.
  • 🎤

Built Different

The RZ75 is not just a speaker — it's a piece of hand-crafted engineering. Every layer, from the microcontroller to the LED matrix, was designed and programmed from scratch.

🔬
Custom Microcontroller
An embedded MCU runs the LED logic, processes microphone data, and drives all 75 ARGB LEDs in real time — at up to 500 samples per second.
💡
75-LED ARGB Matrix
A precisely arranged grid of individually addressable ARGB LEDs creates seamless patterns — each pixel is independently controlled for maximum visual impact.
🎙️
Live Microphone Analysis
The onboard microphone continuously samples ambient sound, extracting bass, tempo, and frequency data to drive dynamic, audio-synced lighting effects.
📐
Student-Designed Shell
The housing was designed and built as a complete SNT project — from 3D modelling and material selection to final assembly and quality testing.
📶
Bluetooth Connectivity
Built-in Bluetooth chipset for reliable wireless pairing. Low latency, high fidelity — supports modern codecs for the best audio quality over the air.
🛡️
1-Year Warranty
Full 12-month warranty on all components. Every unit is tested before shipping — because a product you make yourself should be one you stand behind.

FAQ

Questions &
Answers

How does the audio-reactive lighting work?
▼
The RZ75 has a built-in microphone that continuously analyzes sound. A microcontroller extracts bass, beats, and frequency data and maps it in real time to the 75 ARGB LEDs — making the lights dance, pulse, and flare in sync with any music or ambient sound.
Does it work without music playing?
▼
Yes! The microphone reacts to all sounds — a handclap, a voice, background noise. Even in a quiet room, a single clap will trigger beautiful light animations.
What devices can I connect to the RZ75?
▼
Any Bluetooth-enabled device works — smartphones, tablets, laptops, computers. Simply pair it like any other Bluetooth speaker. No app required.
Can I change the LED colour after purchase?
▼
Yes, you can cycle through all 10 preset colours using the physical button on the unit. The colour choice you make at purchase sets the default startup colour.
What is the warranty?
▼
Every RZ75 comes with a 1-year warranty covering all components. If anything fails under normal use, we repair or replace it — free of charge.
How is the RZ75 priced for launch?
▼
The launch price is 1.500.000 ₫ — a 17% reduction from the standard retail price of 1.800.000 ₫. This offer is available for a limited time during the launch period.
How loud is 20W?
▼
20W is enough to fill a medium-sized room with clear, room-filling sound. It has strong bass response and clear mid-to-high frequencies — ideal for parties, study sessions, or everyday use.
Who made this?
▼
The RZ75 was designed and built as a student project in an SNT (Sciences Numériques et Technologie) class, combining electronics, programming, and industrial design — a real product built from scratch by students.
