A brand new, never used, High Quality piezoelectric earphone, no plug, flush cut leads (NOT stripped and tinned as shown in photos); with a plastic double ear headset!

By utilizing both ears, you will gain increased sensitivity, and greatly reduce external noise!

In our tests, we were able to hear faint stations not audible with an earphone only.

EASILY connects and disconnects to the earpiece, so you can also use the earphone separately if you want too.

Use these for crystal or simple transistor radio design projects, or anywhere else a sensitive, high impedance earphone is needed.

These units will produce a crackling sound just be rubbing the leads together!  Shade of blue may vary slightly from photo
