Very good quality! I use to use a Samsung bluetooth for many years, and I finally decided to switch over as it was not holding a charge, and I think I made the right choice! This headset has a battery life much longer than my previous, and the sound quality is very good. Currently, I use this headset during my daily commute to and from work, as well as working hours, and never even need to switch batteries. I work 8 hours a day and talk on the phone for about 6 of those hours!
