I bought these to replace my LG headset which kept dropping audio during phone calls.  The sound quality is very good.  It has a longer range than the LG. Overall very pleased.  The software that runs the headset is not as advanced as the LG, it doesn't announce the battery level and it can only be connected to one device at a time.  When it announces it is connected, if two of your devices have bluetooth on at the same time, you don't know which one it is connected to because it does not identify the unit it is connected to.
