Koss SB40 mobile headset

SB40 Multimedia Stereophone, 20 - 20000 Hz, Black, Dual Entry Ideal for gamers who enjoy deep bass, the SB40 features a dynamic element for premium sound at all volume levels. Incorporating a frequency response of 20-20,000Hz, the SB40 delivers a full-range of sound that will bring your favorite games to life.

Whether you're alone or online, the SB40's sound will be so efficient that you'll hear your opponent before they even know you're there. Its large, closed ear cups surround the ear for maximum isolation so you can stay focused on saving the world or kicking a forty-yard field goal.

Built to last, the SB40 is covered under Koss’ Limited Lifetime Warranty - the only warranty of its kind in the stereophone industry.
