Whether alone or online, the Koss SB49 full size communication headsets bring the action in your video games to life. Like Kossâ€™ 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 youâ€™ll hear your opponents before they even know youâ€™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. Whatâ€™s more, Kossâ€™ Clear Voice Technology (CVT) noise cancelling electret condenser microphone eliminates excessive background noise for clear communication.
