User questions & answers

Question:	CAN I USE A DOUBLE EAR BUD
Answer:	No
Question:	just how durable is this device as I can't afford a second one senior 85 yr.old
Answer:	I know I answered this question before --- I sent it back almost immediately. I bought it so I could listen to the TV at night at a much lower volume so as not to disturb my husband more than was necessary. It produced too much static and background noise. I couldn't hear the TV which was only 10 or 12 feet away. The quality was flimsy and just didn't do what it was advertised to do. Bite the bullet and see a professional audiometrist (Medicare and your secondary insurance should pay all or most of the costs) and see if you qualify for properly fitted hearing aids customized to your particular needs. Sorry; I know what you're going through. I'm a senior citizen with a 94 year old mother whose hearing aids are getting less effective every year.
Question:	Is there a sound amplifier with equalizer and bluetooth ear bud
Answer:	Reizen currently does not sell personal hearing amplifier with Bluetooth earbuds and equalizer feature. Should you have any questions about any Reizen products, please don't hesitate to reach out to their customer support at 1-800-522-6294. Their support team will be happy to assist you.
Question:	I Getting a buzzing noise Is that normal
Answer:	Pi seem to get a buzzing sound occasionally when it is very close to my cell phone. Maybe some kind of interference but as long as cell is a foot away from unit, it works fine

Product description

Works on wooden walls, doors, windows, steel plates, etc.

Highly Sensitive, carefully adjust audio slowly, as not to cause discomfort to your ear-buds

Description:

As simple and powerful as possible from a handheld listening device, this audio gadget can let you hear conversations

through walls and other barriers.

So how does it work Simple, you switch on the Inspector Gadget Audio Listening Device, insert the earphones, and then

place the audio bug on the wall and listen to what's being said.

This audio gadget works by amplifying the vibrations of audio. When people are talking in a room their voices are simply a

waveband, and depending on how loud they are talking, the waveband travels short and long distances which are picked

up and amplified by this device.

The sensor on this audio gadget senses the vibrations hitting the walls, ceiling and floor and amplifies them so that you

can listen to whats being said. If the waveband is low, meaning people talking in a lower note, then you can use the dial

located at the back of this cool audio gadget to adjust the volume and increase the sensors amplification. It really makes ""

more fun and productive.

Lets face it, no one really tells the truth straight to your face. So why not find out the truth, you will be amazed what people

might say when your whether you are in a motel room, hotel room, your apartment or just in the next room the device will

let know whats being said.
