"Two words: 'I wish!'" Wi-Gear CEO Mark Pundsack said via email, when asked about the rumours that Apple had bought the company.
News of the supposed acquisition was helped along by the fact that Wi-Gear's site currently says the company is out of business. In addition, the LinkedIn profile of former Wi-Gear co-founder and engineer Michael Kim now lists his position as a iOS Bluetooth engineer at Apple. But Pundsack says that there's no truth to the purported purchase by Cupertino, adding that "Wi-Gear and its IP are still available for sale." In a followup e-mail, he added that Wi-Gear had ceased operations due to a lack of funding.
Of course, it's certainly possible that Apple is investigating adding Bluetooth headphones to its line-up--perhaps even with the help of Kim--but it will have to do so without the benefit of Wi-Gear's technology.
