Q. When using this device answering calls to a mobile phone is the device directly connected to the mobile phone or is will it sork efficiently wothout being connected? Why are you not providing a speaker with the kit
A. Hi Will, thank you for your question. Velleman - the manufacturer - do not provide a speaker unfortunately. It can be any speaker depending on the sound you want, we recommend 35-0150. The device is not connected to the phone; when on a call you would speak into the voice changer microphone and the speakers then plays into the microphone of the telephone.

Easy project, built a few, one as a gift etc... Sounds grand, and with a bit of tinkering you can get more out of this unit. Just make sure you get a speaker to match.
