SPY EAR SOUND AMPLIFIER
ispy007, $4.95 ozspy.com.au ★★ Little more than a toy, this amplifier can pick up conversations up to 7m away. It needs line-of-sight access to its subjects to work effectively. Essentially, it cannot amplify sounds through walls but it does have a sensitive microphone that will amplify low-voiced conversations to a comfortable hearing or recording level. However, the speaker needs to be in the same room as the listener and the bright blue device needs to be pinpointed at them. It comes with headphones, batteries and instructions, although its on/off and sound dial are simple enough to operate.
