Monaural earphone for voice recorders

This monaural earphone is designed for use with Olympus voice recorders. It connects via a 3.5mm plug and delivers a frequency response of 300 to 5,000 Hz. The 16-ohm impedance and 94 dB/mW sensitivity suit dictation playback. A 3.8-foot cord provides convenient listening range.

Suits single-ear monitoring, not stereo

The single-ear design lets users hear recordings while staying aware of their surroundings. It suits transcriptionists, interviewers and students who need one ear free. Buyers who want stereo music reproduction or noise isolation should look at something else.

3.5mm plug compatibility decides fit

The 3.5mm plug is the only connection option. Verify that your recorder or playback device has a matching 3.5mm jack before purchasing. Adapters are not included and the plug type cannot be changed.

Questions about this item

Will the 3.5 mm plug on the 146112 earphone fit my recorder's jack?

Yes, the 3.5 mm plug is the standard size used by most voice recorders and dictation devices.

What is the step people miss when plugging in the E-20 earphone?

Push the 3.5 mm plug in until it clicks; a partial insert gives mono sound or no audio at all.

How long before the cord on this 3.8 foot earphone needs replacing?

The cord is fixed; replace the whole unit if the cable frays or the 16 ohm driver fails.
