Review on Koss SB40 Computer Headset with Built-in Microphone by Austin Hampton

I bought the SB40 to use with a Kenwood TS-590S ham radio. Kenwood uses a dynamic mic, and the SB40 mic works fine with no modifications (other than adding an adapter to connect the wireless input). The muffs are comfortable, as is the hanging headband. I get good quality reports even when comparing A/B to the Heil 12 which I use as a desktop mic. The TS-590S supports EQ tuning and I used the same profile on both the SB40 and Heil 12. The price ($30) makes it the best value for money.
