On the record

Taping cellphone calls has not been possible until now because of
interference from the radio waves that radiate from the phone. The £20
Watsonmike solves the problem. It consists of a small rubber tube with a foam
ear pad at one end and a miniature microphone at the other, where it is safely
out of range of the radio-frequency interference. Sound from the cellphone’s
speaker passes down the tube to the microphone.
