Every lab coordinator hits the same question at purchasing time: do I buy one headphone per computer, or budget for the pairs that will inevitably go missing or break mid-year? Get the number wrong and you are either short during a testing window or sitting on a drawer of unused units. Here is the simple rule, plus the two headphones that make the math cheapest to live with.
Buy one headphone per device, plus about 10% spares to cover loss and breakage during the year. For a 30-seat lab, that means roughly 33 headphones. For the per-seat unit itself, the AVID AE-35 at $9.49 is the standard: low enough to buy one for every seat plus spares without straining the budget. If you would rather spend a little more to reduce replacements over time, the Hamilton SC-7V at $12.29 adds replaceable cushions and volume control, so a worn pad does not mean a whole new headphone. Order in lab-pack quantities and add the 10% cushion up front. Encore Data Products quotes volume pricing and accepts school POs at 866-926-1669.

The AVID AE-35 is an on-ear classroom stereo headphone at $9.49, which is exactly the price point that makes one-per-device-plus-spares easy to justify. When you multiply the unit cost across an entire lab and add a 10% spare cushion, a low base price keeps the total order affordable. It uses a standard 3.5mm plug and has no microphone, matching the listening tasks most lab software requires.
For sizing a lab, the AE-35 is the default per-seat unit: cheap enough that the extra 10% of spares barely moves the total, and dependable enough to survive shared daily use.

Because you can swap a worn or torn pad instead of discarding the whole headphone, the effective replacement rate over a multi-year lab deployment drops, which can offset the higher upfront price.
Choose the SC-7V when you are planning for the long haul and want to reduce the number of full-unit replacements each year. For the lowest upfront cost per seat, the AE-35 is still the better starting point.

Replaceable cushions and volume control to cut replacements
The Hamilton SC-7V is not the runner-up because it is a lesser headphone; it is arguably the smarter long-term buy thanks to its replaceable cushions and volume control. It ranks second here only because the question is about quantity, and the AE-35's lower per-seat price is what makes the one-per-device-plus-10% rule easiest to fund up front. If your lab plans in multi-year cycles and you want to minimize full-unit replacements, the SC-7V is the better long-run value.
The rule is simple: one headphone per device plus about 10% spares. For a 30-seat lab, order around 33 units so a broken or missing pair during a testing window never leaves a student without audio. Build the 10% cushion into the initial order rather than reordering in a rush later.
For the per-seat unit, the AVID AE-35 at $9.49 keeps the whole order affordable, while the Hamilton SC-7V at $12.29 lowers long-term replacement cost with swappable cushions and volume control.
