The deal is Logitech’s largest acquisition and is part of its cunning plan to diversify. Last year, it wrote a cheque for ASTRO Gaming so that it could expand in the video game sector.

The deal means that Logitech and Plantronics seek to keep down manufacturing costs after Trump’s trade war with China.

Logitech has offered more than $2.2 billion to acquire Plantronics, one of the sources said. Plantronics had a market capitalisation of about $2 billion.

If it all pans out, a deal between Logitech and Plantronics could come as early as next week, the sources said, cautioning that it was also possible that no agreement would be reached.

Founded in 1981, Logitech has been countering declining sales of personal computers by focusing on consumer accessories that are benefiting from the growth of cloud computing, such as gaming, music, smart home connectivity and video conferencing. It has a market capitalisation of $5.6 billion.

Plantronics makes unified communications systems, wireless headsets, conferencing systems, and some software, which it sells to businesses and consumers.
