I don't know if this is good news or bad news.

When you say "with our latest generation A6 devices", does this mean  
that those new devices have hardware changes designed to improve audio  
quality relative to the Neo1973 and first batch of Freerunners? Or is  
the hardware still the same and you are just unable to reproduce the  

Also, I hope that the "echo" problem (#1267) is getting as much  
attention as the "buzz". On my Neo1973 I can hear buzzing but it is at  
a tolerable level. However, the echo can be loud enough that the  
person on the other end of the call is not able to carry on a  
conversation. This issue is the main reason that I haven't yet  
purchased a Freerunner.

p.s. I know that it is possible to "get rid of" the echo by turning  
down some of the mixer controls. The trick is to get rid of the echo  
while keeping those mixer elements high enough that the two people on  
the phone call can still hear each other talking.
