Aune B1S

Class A Discrete Headphone Amplifier

Aune B1S

The Aune B1 back!

The Aune B1 comes back in an improved version, the Aune B1S. Like its predecessor, it benefits from a Class A design and has been designed to power the most demanding helmets.

Class A in reduced format

Aune achieves the feat of integrating a Class A amplifier into an extremely small format. A design that will allow the amplifier to deliver rich, warm, generous, just and powerful sound to your music.

Aune B1S Class A

Adjustments to all headphones

The B1S has settings on its sides to adjust the amount of current used for amplification or gain adjustment. Thus, the amplifier is able to drive all types of HiFi headphones.

Aune B1S THD+N

An adapted battery

DAPs have developed rapidly in recent years. The B1S is the solution that will allow you to effectively amplify your DAP signal, ensuring an extremely low distortion of 0.0002%.

Un design sublime

The Aune B1S asserts itself with an inspiring design that is both robust and stylish. Black brushed Aluminium, the amplifier also has two windows that reveal its components, the heart of the amplifier.
