The HamiltonBuhl Primo is a workhorse elementary headphone that comes in two flavors: clean solid colors like blue, or the kid-magnet Panda pattern. The audio and build are the same; the choice is really about what lands with your students and how you like to organize a class set. Here are the colors, the prices, and how Sack-O-Phones multi-packs fit in.
For most elementary classrooms, the solid-blue HamiltonBuhl Primo (PRM100) at $10.99 is the best default: a clean, uniform look that is easy to standardize across a class set and simple to inventory. The Primo Panda (PRM100P) at $9.97 is actually a bit cheaper and adds strong kid appeal with its panda pattern, which is a great fit for PreK through lower elementary. The audio specs and build are the same across both, so pick on look and organization. Both are stocked at Encore Data Products, and Sack-O-Phones drawstring multi-packs are available when you want a class set bagged together.

The pattern is a hit with younger students, which helps with buy-in at listening centers and 1:1 stations in PreK through lower elementary. Audio and build match the solid Primo exactly.

Choose the Primo Panda when kid appeal helps, such as early-childhood rooms, or when you simply want the lower price. The solid-blue Primo edges it only when you want one uniform color across a larger set.

The Primo Panda is not a lesser headphone; it is the same Primo with a fun pattern and a slightly lower $9.97 price. It ranks second only because the solid-blue Primo is easier to standardize and inventory across a whole class set, which most buyers weigh heavily. If your priority is student buy-in in an early-childhood room, or simply the lower price, the Panda is the better choice. Both are the same headphone underneath, so you can even mix them, patterns for the little ones and solids for the rest.

The Primo comes in solid colors and kid-appeal patterns with the same audio and build, so the choice is about look and organization. For most elementary classrooms that want a uniform, easy-to-inventory class set, buy the solid-blue Primo (PRM100) at $10.99. For early-childhood rooms where student buy-in matters, or when you want the lower price, the Primo Panda (PRM100P) at $9.97 is the call.
