Hamilton Buhl SOP-PRM100 Sack-O-Phones - headphones

Sack-O-Phones is a unique storage and carry bag that doubles as a knapsack, and this one holds 5 Primo headphones with a 3.5 mm plug. Each Primo headphone comes in its own heavy-duty, anti-lice, write-on, moisture-resistant, resealable bag.

Greater focus in their lessons allows students to attain better listening skills and higher literacy. Primo headphones have noise-reducing ear cups that are designed to provide these benefits from the classroom, to the laboratory.
