HamiltonBuhl Primo Stereo Headphones

One of the building blocks to successful student learning is to teach listening skills that help develop comprehensive language and literacy. Teachers find that students excel, when they are more focused on their lessons, in classrooms, labs, libraries, and testing environments.

Primo headphones are uniquely designed to provide the perfect blend of all of these.

Noise-reducing ear cups allow students to clearly hear their lessons, protected from unnecessary and distracting ambient noise, as well. Made of ABS plastic, with the exclusive chew, kink and knot-resistant Dura-Cord, and 3.5mm stereo plug, these rugged and reliable headphones make it a versatile unit to connect to almost any audio device: tablets, smartphones, computers and more.
