Classroom headset with dual impedance

The Telex Discovery DS-4v is a wired stereo headset built for classroom and training environments. It uses a mini-phone connector and a six-foot cable. The binaural ear-cup design includes a boom microphone. Vinyl materials avoid latex allergens and allow easy cleaning between users.

64 Ohm and 300 Ohm selectable impedance

The headset presents two input-impedance options, 64 Ohm and 300 Ohm, so it can match a wider range of audio sources. Choosing the correct setting ensures proper volume levels and frequency response without needing an external adapter. This single specification determines whether the headset will work cleanly with a given device.

Cord rated for 250000 flex cycles

The cable is tested to survive 250000 flexes, and the headband withstands repeated twisting and bending. Speakers resist damage from pens or paper clips. These durability measures mean the headset maintains consistent audio and microphone performance through daily classroom handling rather than failing after short-term stress.

Questions about this item

How do the 64 Ohm and 300 Ohm impedance ratings affect volume and compatibility with classroom devices?

The 64 Ohm setting works well with standard computer and tablet outputs for typical classroom volume levels. The 300 Ohm option suits specialised audio equipment that requires higher impedance for proper signal matching.

What does the mini-phone connector limit in terms of audio channels and microphone support?

The mini-phone plug carries stereo sound to both earcups and the boom microphone signal on a single cable, so it fits the common combined headset jack on laptops and classroom PCs.

Will the 6 ft cord reach a desktop tower placed on the floor from a student desk?

A 6 ft cable spans roughly 1.8 metres, which is usually enough to connect a headset to a floor-standing tower from a standard desk without pulling tight.
