It all started with a $349 microphone called The Podcaster. It sounds nice in that it plugs in via USB which means no batteries (for the mic, at least) and is "specially" made for podcasters, but the price is outta this world.
Aptly named the Podcaster, the microphone simply plugs into any PC with a USB port via its 5 m USB cable. Rode says the frequency response is tailored for voice, with low self noise, and a switchable high pass filter. It has an “ON” LED, and direct headphone amp.
There's a fundamental flaw in the pricing model of hardware aimed at podcasters. Companies are attempting to produce specialized podcasting hardware (like that's needed??) an attempting to entice podcasters to buy the stuff. The thing that many companies are missing is that they're still pricing their wares for the pro radio industry. They're trying to marry up Joe podcaster who does this for fun and doesn't make any money and a product aimed at professionals.
It's not going to work.
My $30 headset is doing juuust fine and it's not even USB.
