Rugged Stereo Headset for Learning

The Ergoguys 3066AV Califone is a wired over-ear headset built for classroom and lab environments. Its ABS headstrap with recessed wiring resists tampering, while the adjustable band fits a variety of head sizes. A 1.57 inch driver delivers stereo sound across a 20 Hz to 20 kHz range at 300 Ohm impedance.

Wired IR Connectivity Limits

The headset uses a permanently attached 7 ft cable ending in a nickel-plated mini-phone plug for a direct wired link. Infrared wireless capability is also specified, though the primary connection relies on the physical cord. The fixed cable cannot be swapped or extended without modifying the unit, so placement is restricted by its length.

Check Your Device Before Ordering

Verify that your computer or audio source provides a compatible mini-phone jack for the stereo connector. The 300 Ohm impedance may require a dedicated headphone amplifier or a device with sufficient output voltage to reach desired listening levels. Ensure the boom microphone with integrated windscreen meets the input requirements of your VoIP or recording software.

Questions about this item

Should I pick the 300 ohm version or a lower-impedance model for classroom computers?

The 300 ohm impedance matches typical classroom audio ports and language-lab equipment, so it works without an extra amplifier.

What does the 20 Hz to 20 kHz range mean when students are using the headset for language lessons?

It covers the full speech band, so every phoneme from deep vowels to sharp consonants comes through clearly.

How does the IR wireless type and mini-phone connector affect daily use in a computer lab?

The headset connects by a 7 ft wired cable with a nickel-plated mini-phone plug; IR is not used for audio transmission.
