Review on Koss SB40 Computer Headset with Built-in Microphone by Frank Webster

Purchased to skip the preamp/compressor/EQ stack and trip over my ham radio setups. I just wanted a decent "dynamic mic" sound, so I went with the SB45. Boy super disappointed. Extreme response at mid frequencies (1-3 kHz) on the microphone and the almost complete absence of low frequencies; the noise level is high, the output signal level is not so good. I had to turn on a super sharp gate and about 10dB of scoop for it to even sound usable - and all I can use is 200Hz to 3kHz. I've used it in everything from a USB audio dongle to a tube mic preamp and nothing could warm it up enough. The headphone side is fine, if a bit boomy and harsh. The cable is good and long, this is a pro. And they're pretty comfortable. External soundproofing would be somewhere on the good side of average. With that in mind, a few bucks have been spent on a product that could use a little hype. I'm thinking of the SB45, or maybe cutting off that dynamic piece of junk at the end and sticking an electret in it. bin anyway.
