In comparison to other models of wall contact microphones, FL999 does not have a needle so it provides higher comfort of use – it does not generate any additional, ear-irritating sounds and is more sensitive than standard needle wiretaps. The system of band filtering provides better amplifier profile and directs the wiretap mostly on human speech, so we obtain a clear sound of conversations.

The Super Sensitive Wall Contact Microphone - FL999 also allows to record and save the files from the listening-in, after plugging the recorder or a voice recorder, which are available in our shop.

FL999 wall contact microphone is designed for everyone who needs functionality, full safety (it is not detectable by electronic safety devices) and very good sound quality..

The device is not water resistant.

Comment : I did a few tests, I do not trust blindly everything that is written and this device is indeed not detecteable by electronic safety divices. Other features also work as stated in the product description. So this Super Sensitive Wall Contact Microphone is a device you can trust.
