One hundred HamiltonBuhl Primo Red stereo headphones in one order. Primo is a durable on-ear listening headphone, and the red color makes class sets easy to tell apart. The chew- and kink-resistant Dura-Cord and wipe-clean cushions are made for K–12 classrooms, labs and Chromebook carts. At $12.59 per headphone, this pack standardizes a grade level or a whole school on one model.
Listening only: this model has no microphone. If students need to speak or record, choose a school headset with a microphone instead.

Why schools choose Primo
- Built for schools. ABS construction and a braided, PVC-sleeved Dura-Cord that resists chewing, kinks and knots.
- Wipe-clean cushions for shared classroom use.
- Noise-reducing earcups that help block classroom distractions.
- Storage bag with each headphone, write-on and reclosable, so each student keeps their own.
- One model everywhere. A 100-pack keeps every room on the same headphone, which simplifies replacements.
Device compatibility
Plugs into the 3.5mm headphone jack on Chromebooks, laptops, desktops, tablets and listening-center jackboxes. For USB-C-only devices, add a USB-C to 3.5mm audio adapter.
Classroom uses
- Digital lessons, lesson videos and audiobooks
