High Impedance Ceramic Earphone - CH905
CH905 is very sensitive and works great with crystal radios.
Crystal radios can fee magical, given their ability to tune in audio from distant stations with nothing but the energy from the radio signal itself. To achieve this feat, they typically rely on a high-impedance ear to produce an audible sound with very little current.
Kindly send us your specification drawing(s) or design requirements and we will be happy to prepare our most cost effective proposal. Feel free to contact us with any questions that you might have.
