SSB-021 stethoscope wiretap is a very advanced device which allows to receive wiretapped signals in stereo, even through walls, giving a clear and sharp sound.
Unlike other similar devices of this class, SSB-021 is equipped in double system of piezoelectric converters and microphones, which makes the whole system work better. Two microphones, placed on the wall, capture waves vibration caused by a conversation; the wire transfers them to the receiver which amplifies and filters all the tones. The generated sound is clear very distinct and using two microphones allows to listen-in in stereo quality. Additionally, using the wire instead of wireless communication increases the safety of use. The wiretap becomes undetectable.
The product is recommended both for professionals from the detective branch who need an equipment of very high quality and for amateurs of very high requirements who look for a safe solution.

Comment : This stethoscope is a highly advanced product for professionalists searching for something fully reliable, providing clear sound and undetecteable. Not suited for amateurs, I think
