I have had numerous BT headsets and this one out performs them all in every area. I have been using it now for almost 6 months and feel comfortable reporting that the inbound and outbound voice quality is very good. I travel and am in the car and airport frequently. That said, I no longer have people telling me they can't hear me or they hear too much background noise. To me, this is what makes this unit a great headset.This unit also has good battery life (3-4 hours).
