Yes Tony. They work the same as headphone/microphone. The echo is feedback through the Bluetooth. I've not tried one of those. I have always used headphone/microphone. These can also give an echo. It is down to the actual connection speed at both ends too and traffic. I remember going back 15 years when phone calls from Tenerife were the same.
