Fatigue-free headset for classroom testing This Hamilton Buhl headset features an inline microphone and on ear volume control. Like the Deluxe Headset with Gooseneck Microphone, it has a lightweight design and comes with swivel ear cups, adjustable headband, soft leatherette ear cushions and a 4' chew-resistant, braided nylon cord, as well as a 3.5 mm stereo plug. Developed for fatigue-free use in and out of the classroom, it's also comfortable to wear and compatible with most devices, including smartphones, iPads, chromebooks, other tablets, laptops and computers — making it the perfect solution for classroom testing environments. The microphone features an inline mute button too. The Deluxe Headset with Inline Microphone is easy to clean, and available in blue.
