Lab Research and other DIY experiments require a very sensitive high impedance headset. SoundLAB Crystal Earpiece earphones also known as Ceramic earpeice, crystal headphones or piezo headphones are the most sensitive headphones. They are in fact many times more sensitive than even the most sensitive headphones, dynamic magnetic headphones, or electrostatic headphones that you can use on your iPod or iPhone. Sensitive Sensitive hearing aids have a very high impedance, which is measured in ohms and should not be used directly with a modern amplified radio. Crystal Headphones are so sensitive and require so little power to operate that you can hear a tiny 'click' simply by touching the 3.5mm connector. Crystal Crystal radios will not work with modern headphones or "headphones" because they are designed to work with amplified audio sources found in today's electronic devices. Crystal headsets are used in the construction of crystal radio and in some science experiments such as listening to electric fish.
