The newly developed Φ4.4mm balanced connection cable separates left and right sound signals, while minimising signal transmission loss and resulting sound deterioration.

Discover balanced audio
A balanced connection separates audio channels, eliminating interference. This ensures a distinct tone and enhanced dynamic range within an expansive acoustic field.
How does a balanced cable work?
A ø4.4mm connection cable has two polarised signals that cancel each other out, reducing unwanted noise picked up from the wire to the amplifier.
Enjoy pure sound with balanced connection
Plus and minus amps independently drive the right and left signals generating a high stereo effect – so you can enjoy distinct High-Resolution Audio with no crosstalk.
Small, light and durable
With the lightweight chassis and silicone band, you can easily carry the amp with you. Its rugged aluminium case protects it from everyday knocks and shocks.
Enjoy up to five hours of balanced audio connection with a long battery life.
Connect with your device
