Classroom on-ear headphone

The HamiltonBuhl HA2-ORG is a personal on-ear stereo headphone built for daily classroom use. Its lightweight frame and rugged construction handle repeated handling by students. Orange colour coding helps quick identification in shared environments. The package includes one headphone with replaceable foam ear cushions.

Check device jack and cord reach

Verify the source device has a 3.5 mm audio socket; the 120° thin barrel plug fits through most protective cases. The Dura-Cord extends from 3.0 to 5.0 feet, so confirm that reach suits the desk layout. The 32 ohm impedance matches typical tablet, laptop and desktop outputs. No additional adapters are required for standard ports.

Light weight and passive cooling

At 0.15 lb the headphone adds negligible mass during long lessons. On-ear pads rest on the ear rather than enclosing it, allowing natural airflow and reducing heat build-up. Passive operation draws no power from the connected device. The braided nilon cord resists chewing, kinking and knotting, minimising handling noise.

Questions about this item

Does the package include anything besides the headphones themselves, such as a spare cord or extra ear cushions?

Only one headphone is included in the box; replacement foam ear cushions are available separately but do not ship with the unit.

The cord length is shown as a range from 3.0 to 5.0 feet — is that a retractable cable or a fixed length?

The Dura-Cord is a braided, PVC-jacketed cable that resists chewing, kinking and knots; the range reflects its natural relaxed and extended lengths rather than a retractable mechanism.

With a sensitivity of 90 dB and 32-ohm impedance, will these get loud enough from a tablet or Chromebook without an amplifier?

Yes, the 32-ohm load and 90 dB sensitivity are well matched to the headphone outputs on typical tablets, Chromebooks and laptops, so an external amplifier is not required.
