Holdinvader

The Hold Invader. Clip it to your landline phone and turn the phone on the other end of the line into a ‘super sensitive listening device’. Sneaky is, as sneaky does! £116.33.

 Perfect for negotiations being conducted over the phone. Simply attach this to your phone. During a conversation you tell the person that you are talking to that you need to put them on hold for a short while. Whilst the other party thinks they are on hold their telephone has, in fact, been turned into a super-sensitive listening device. The unit even gives a ‘call waiting’ sound and you will be able to hear what they are saying.

    Mmm…got the feeling that it must amplify the signal from the other end too though?
