the product looks ok. when the intercom mode is on, a buzz sound is coming like zzzzz....when music is played it is not there . Also one of the bluetooth device light is slightly on always .it is not switching off completely. also the package was poorly made ..due to sanitization, it seems ,the whole package was flooded with sanitised liquid ..luckily the units are working ..please do good plastic package especially now a days as customs do sanitisation on the packages in Saudi Arabia
one of the headsets was injured and don't work
