“Flat out of the box”

The fully hand-built headphones from Ollo Audio are made from high-quality environmentally conscious materials.
The special feature of this headset is that it works without correction software (DSP), sophisticated electronics and DA conversions.
It sounds pure, which is extremely pleasant if you want to experience music as it was intended. Lively, wide, transparent and natural.

The audio quality is achieved with the aid of acoustic compounds, such as also commonly used in the better speakers.
This allows you to enjoy all the nuances in music.

Because the ear cushions are made of acoustic foam and extra elastic artificial leather, the wearing comfort is extremely high and you can also listen to long music sessions without getting tired or irritated.
