According to German publication Handelsblatt, part of the reason why Sennheiser is looking to sell its consumer side of things is because it was late to the TWS party. This meant that the company failed to carve out a satisfactory share in the market. On top of that, headphone sales has not been performing as the company hoped.
And while the official Sennheiser press release says it is looking for partners for its consumer business, it’s not opposed to selling it off completely. The Handelsblatt interview with the two Co-CEO brothers had indicated “all options are open”.
