Apparently, the firm wants to shift its focus entirely to professional audio, including its Neumann microphone division and what Sennheiser calls business communications.

In a press release, Sennheiser says it wants to increase visibility in the competitive headphone and soundbar markets, and it thinks its products can be popular amid "strong competitive pressure". But it needs an investor to make that happen. It also says that talks with potential partners will start soon.

Sennheiser co-CEO Daniel Sennheiser said: “To be best able to exploit the potential in each of these markets, we are concentrating our own resources on the three business areas in the Professional division and are looking for a strong partner to invest in our Consumer business."
