Two way Headsets

I went to find some headsets for the new office. The present one just for listening without having the micro-speakers. That's just one way in listening. I need to have both for conversations for the Skype conversations.

We need two-way communications in our fellowship with the Lord.
One way listening is fine but we still need two-way for satisfactory talks.

It's amazing that the present headsets are so cheap. I found one shop offering just $ 18 dollars per set. Last year I bought one for over $ 30 dollars. The decreasing price means more demands for the increases in supply. That also means that more persons use modern technology.
