The company said it had hired Henrik Clausen, most recently the global head of strategy at Norwegian telecom group Telenor, to replace Tue Mantoni, who took the helm of Bang & Olufsen in 2011.
"Tue initiated a dialogue about his longterm commitment with the board of directors some time ago," chairman Ole Andersen said in a statement.
"Following the completion of a number of important projects Tue will now step down as chief executive," he added.
The company said on April 15th it had ended takeover talks with China-based billionaire Qi Jianhong, the group's largest shareholder, and his holding company Sparkle Roll after the expiry of a deadline for a bid.
"As Sparkle Roll has not committed to launch a tender offer for all shares in Bang & Olufsen and has not been able to substantiate its ability to launch such a tender offer, Bang & Olufsen's board of directors has today decided to inform Sparkle Roll that it considers the dialogue regarding a potential tender offer terminated," it said in a statement.
Talks began in November, and in March Qi revealed that he was interested in buying the company for a "reasonable" price.
