I purchased this to replace has this giant collection of headsets to phone I use with my mobile. Constantly I am on the phone for my job and I need this to keep my hands free. Unfortunately i never found the right headset with qui people can hear me Clearly. The AKG and high range is definitely a great choice and headphone to listen to music with. Purpose Unfortunately, people still hear me very badly When using it to call someone, Even Though I try not to move and make safe the Mic Does not touch Any Other object like a shirt collar etc ... I miss the days of the good old fashion headsets sold with the Nokia phones Back Then, Those Were working fine with no one making the différence entre using the headset or the phone!
