Bose has sued Beats Electronics over noise-canceling technology it says is wrongfully being used in the latter companys headphones. Until now, the two have managed to coexist peacefully in the headphone market, with each finding lucrative success. Beats is of course in the process of being acquired by Apple. A lawsuit is unlikely to affect that deal, but may pose an unwanted and early challenge for Apple once it assumes ownership of the company. CNBC was first to report the lawsuit. Beats uses noise cancellation technology in its Beats Studio, Beats Studio Wireless, and Beats Pro headphones.
