Did NOT work on the first attempt
When I tried to use it but it did not work because I was using old 9v battery's. I thought it was a scam and placed a return order but then I went to a shop and purchased two new 9v battery's. I started crying because it worked. The sound quality is not the good but it is audible/understandable enough.

Low Volume
The volume even at max is not loud enough with iPhone. I tried with other devices and it is slightly louder. I have to place the copper closer to my ear to make it louder which is not the design.Batteries are brand new as well but volume is too low. Maybe a fix for that?
