Whether alone or online, the Koss SB49 full size communication headsets bring the action in your video games to life. Like Koss’ other communication headsets (the SB40 and SB45 models), these communication headsets deliver high noise sensitivity and reduced sound distortion for a premium sound at all volume levels, ideal for gamers who prefer deep, sound bass. 

Incorporating a frequency response of 18-20,000 Hz, the SB49s are so efficient you’ll hear your opponents before they even know you’re there. Large, closed ear cups surround the ear for maximum isolation, while soft, leatherette ear cushions deliver comfort that lets you game for hours on end. What’s more, Koss’ Clear Voice Technology (CVT) noise-reduction electret condenser microphone eliminates excessive background noise for clear communication.
