Title: This product does not work
Review: These things did not work on either my wall phone or on my princess-type phone. One resulted in dead air; no connection at all, and the other created nothing but a shrill whistle. I have no idea why they did not work. The enclosed literature didn't offer any clues. So I sent them back. I truly needed a product that raised the volume on incoming phone calls but these left me sorely disappointed.
