EM Digital Voice Recorder tiny series - Model a21

Voice recorder hidden in a keychain A21

Unexpected micro recorder hidden in an ordinary leather keychain. The weight and small dimensions help to avoid suspicions. These details, however, don't inhibit the great potential of the digital recorder: long recording time (up to 300 hours with sampling frequency of 8 kHz and 2-bit compression), low power consumption, wide frequency range (100-10000 Hz), large radius of action and a highly sensitive built-in microphone. It can be recharged via USB.
