I would expect a small amount of feedthrough from the speaker to the microphone. They are mounted on the same frame, and some vibrations are going to get through.
Your only recourse would be to modify the headet to put more isolation (foam or rubber) in the mounting mecahnism. Or You can use a seperate microphone.
Echo during "listen" is because of the processing delay in the sound card and computer. It is pretty short, but noticeable. The only reason you don't hear echo in a telephone is that a small amount of the signal is fed directly to the speaker.
i started recording with audacity and listened to music on quiet. i then played it back and could hear the music clearly. there is no sound leak so i dont think it is a sound isolation issue.
You are not clear what you recorded. To test this you would need to record through the microphone while listing to something else on the headphones. For example, plug the headphones into a seperate music player, phone, etc. and record what the microphone is picking up. Inan ideal world, you would hear nothing or only a faint signal. From the other complaint I just answered, this might just be the nature of this model of headset.
