Ollo designs and produces headphones intended for recording and mixing, with the smoothest frequency response on the market.

At the beginning of 2021, we have started to cooperate with the Slovenian Ollo headphone manufacturer within the framework of small-scale imports, in which case we can get the products to our customers faster than couriers and without logistics fees in the capital region. Then Postman Pat pedals to the rest of the country with a small amount.
