Breakthrough in Bluetooth Audio

Bluetooth technology has long struggled to deliver high-quality sound, but ZEN Blue 3 overcomes these challenges. By merging wireless connectivity with lossless audio transmission and audiophile-grade circuitry, ZEN Blue 3 offers a true audiophile-grade Bluetooth experience for your Hi-Fi system. Experience effortless connectivity, liberated from wires, and enjoy audiophile-grade sound at home. Cut the wires and enjoy freedom and quality simultaneously.

Cut the Cord. Not the Quality.

ZEN Blue 3 uses the latest Bluetooth 5.4. It can receive or transmit CD quality lossless Bluetooth via the aptX Lossless codec, and Hi-Res 96kHz via LDAC and LDHC/HWA.

World's First Lossless Transmitter and Receiver.

3 Function Modes to choose from:
- RX mode (receives Bluetooth from a source device).
- TX mode (transmits Bluetooth to a device).
- DAC mode (wired DAC).

Wired or Wireless.

ZEN Blue 3 can now act as a traditional wired DAC via USB-C or S/PDIF inputs. ZEN Blue 3 has true audiophile-grade, Hi-Fi circuitry and is not just a System on a Chip solution. It uses separate Bluetooth, DAC and Op-Amp chips for superior sound.
