The first pair of controlled loudspeakers crackled to normal sound level. I requested a refund Amazon and ordered a new pair. But it was worse with the second pair received with even greater sizzling. New Amazon back! Y-he has a quality control at Logitech? I would rather pay twice the advertised price and have something usable. Time lost to unpack, repack and return is more binding than a few euros more. Between a deplorable service policy (refusal to warranty products purchased on Amazon, moreover totally illegal), keyboards including screen printing fades after a few months (see my other reviews) and now HP sizzling, Logitech brand disappoints me so I will definitely go elsewhere ... starting with "GOgroove SonaVERSE CRS" HP as small office, which does not seem to have made disappointed. To confirm ...
