Our most rugged headset, the 3066 Deluxe Multimedia Stereo headset is designed for small group or independent learning in computer labs, online or in classrooms and libraries. The 3066 offers ambient noise-reducing, over-ear ear cups to help students stay more on task while minimizing the need to increase the volume for hearing protection. Its noise-reducing microphone is designed to pick up the student's voice - not those around them, while the noise-reducing ear cups help to minimize external distractions and keep students on task. The universal 3.5mm plugs makes the 3066AV a solid choice for connecting to older desktop and laptop computers in classrooms, computer labs, and testing environments.
