In May 2018, a class-action lawsuit
was filed against Logitech for allegedly falsely advertising that its Z200 stereo sound system has four “high-quality” drivers (i.e., the speaker parts that produce sound) when, according to the plaintiffs, the system has only two functioning drivers, while the other two drivers are passive and do not produce any sound.

, Case No. 18-cv-3091, N. D. CA.)
