Review: It is super sensitive - I ordered this product to help listen to mechanical sound vibrations. I haven't tried it for through-wall voice listening, but it is super sensitive. Maybe even too sensitive. I tested it by putting the contact microphone flat on my desk surface. Even on the lowest sensitivity, touching the desk anywhere or sliding a finger across it makes a pretty strong sound. Since it amplifies vibrations as sound, some unwanted sounds may come through also--a computer fan or disk drive, air conditioning, a radio playing in the room, etc. Even moving the cables on this device makes sound, so I will try to plan on positioning the amplifier and cables as needed, then tape everything down and try not to touch anything while listening. It's really sensitive. Be careful for your ears.
Review: Does not record audio as-is. Read on - I do like this product, it works well. I recommend using a dab of hot glue to attach the contact microphone to the wall, making sure not to use too much glue and sticking on the center needle. this will reduce the extra noise from your hand holding it. ALSO! if you look at the side, you will notice there is an opening for an SD card. a regular SD card will not work. there is another piece for this device that will allow you to record. it fits in the opening, I had to look for it on Aliexpress. and it is only $10 plus shipping. So I ordered that and am waiting, then I can update this review.

## Questions & Answers

**Q: I just received my hy929.   the instructions are so very vague.   not enough as to know what to do.  are there more instructions some place else?**
A: Dear friend
Hi again
Please first charge the device for about 5 hours. when you plug in the charger, the device's red indicator lights up, and when the charging is complete, the red indicator lights out.
Normally when you rotate the locator of the device, the device will turn on, and then you can hear the sound,(If it still has no sound,please replace another earphone to try).
Please make sure the microphone and earphone plugs are fully plugged into the device. Insert them firmly and make sure the plugs are in good contact. 

Please note a very important technique to use:
When you put the round microphone close to the wall or the door, be sure to keep your hand still. don't move anything, Otherwise it makes noise because the microphone is very sensitive. it needs a highly sensitive microphone to hear what's going on inside the walls,please understand. 
You just need to keep your hand still and then it can work well

Please try again carefully. if have questions,please tell me 
Thank you very much 
Deng
