Hunting for microphones with a good frequency response, I encountered USB headsets. These headsets apparently come with 'laser tuned drivers'; is anybody aware of of what a laser-tuned driver is in the context of noise cancelling microphones/headphones? What makes a laser-tuned driver a selling feature?
It appears to be Logitech branding. Try this link from Logitech http://www.logitech.com/en-us/70/6059
