The SC-7V SchoolMate is one of HamiltonBuhl's workhorse classroom headphones: over-ear, volume-limited for hearing safety, with cushions you can replace instead of tossing the whole headphone. This page covers what it is, what it costs as a single unit, and how the Sack-O-Phones 5-pack changes the math when you are buying for a whole room.
The HamiltonBuhl SC-7V SchoolMate is a deluxe over-ear classroom headphone with a 3.5mm plug, built-in volume limiting for hearing safety, and replaceable ear cushions. A single unit is $12.29. The Sack-O-Phones 5-pack (SOP-SC7V) is $69.29, which works out to $13.86 per headphone in a labeled carry bag. Counterintuitively the 5-pack costs slightly more per unit than a single, because it bundles the storage bag, not a volume discount. Buy singles for lowest per-unit cost; buy the 5-pack when classroom organization and grab-and-go storage are worth about $1.57 per headphone.

The HamiltonBuhl SC-7V SchoolMate Deluxe is an over-ear classroom headphone built for daily shared use. Its two signature features are a built-in volume limiter that caps output for hearing safety and replaceable leatherette ear cushions, so a worn or soiled pad is a cheap swap instead of a discarded headphone. Distributed by Encore Data Products, the single unit is $12.29.
The SC-7V is a re-order favorite because it is durable, safe, and repairable, the three things that matter most in a shared classroom set.

It is designed for classroom organization: one bag per learning center or cart, easy to count, store, and hand out. At $69.29 the pack works out to $13.86 per headphone.
The Sack-O-Phones bag adds organization, not raw savings. If you only care about lowest cost per headphone, order singles; if you want grab-and-go sets that stay together, the 5-pack earns its small premium.

The Sack-O-Phones 5-pack is not a worse product, it is the same SC-7V with a bag. It ranks second only because the bundle costs slightly more per headphone than singles, so pure cost-per-seat buyers should order loose units. For teachers who value organization and sets that do not wander between rooms, the 5-pack is the more practical purchase.

Both give you the same headphone: the HamiltonBuhl SC-7V SchoolMate with volume limiting and replaceable cushions. Singles are $12.29 each, the lowest cost per seat. The Sack-O-Phones 5-pack is $69.29, or $13.86 per headphone, and adds a labeled carry-and-store bag.
Buy singles when you are outfitting a full lab and want the lowest total cost. Buy the 5-pack when you want organized, countable sets for listening centers or carts and the small storage premium is worth it. Both ship from Encore Data Products with school and district pricing and PO acceptance.
