Classroom 30-pack headphones

This set supplies thirty black headphones, each individually sealed, for classroom, library or testing environments. Adjustable headbands fit children and adults alike. The 3.5 mm stereo plug connects directly to smartphones, Chromebooks, tablets, laptops and computers. Extra-soft ear cushions can be wiped clean between users.

Capacity and headroom

Thirty units cover a full class or lab in a single purchase. The 4 ft cord gives each listener enough reach for desk work without excess cable. Stereo output delivers clear audio for lessons, assessments and multimedia. The pack is not suited for users who need wireless freedom, active noise cancellation or per-ear volume controls.

Thermals, noise and power

Passive operation draws no battery or USB power, so there is no heat or fan noise. Sound leakage stays low thanks to the cushioned ear cups. The lightweight build keeps pressure off the head during long sessions. Buyers who require powered amplification or Bluetooth connectivity should look elsewhere.
