Summary: This headset is your typical cheap computer sound-card lightweight headset, but these have very good receive and transmit audio characteristics. They are comfortable and work great with my FT-950 through a home-brew interface that allows the use of an electret microphone element. (Voltage is taken from the microphone connector.) Rig mic gain is set between 9 and 10 o’clock, so there is plenty of drive from the mic.
Summary: A year after receiving this headset, I still use it! That makes it the longest lasting headset I've ever had. It has never been uncomfortable, I have never had complaints about my sound quality, and I can hear anything and everyone very clearly. If I don't feel like wearing the headphones, i can put it around my neck and position the microphone to speak, and according to the people talking on the other end, it still did not produce any echo.
