Established business with a proven track record

The Company has been engaged in marketing and sales of microphones for more than 15 years, although until recently facing the issue of limited supply of items to sell.

According to the management the year 2021 serves as a good illustration of its current capacity and ability. The 2022 results have been affected by the overall audiovisual market slowdown and by the stagnating sales in China. The  2023 full year results are better than the 2021.

In 2023 the Company restructured its balance sheet by capitalising the loans from shareholders.

The financial highlights are summarised below:
