Headset with miniature directional amplifier

Apparently nothing different than a standard Bluetooth headset.
In actual facts this is an amplified audio microphone to better listen to sounds and conversations up to a maximum distance of 10 yds/meters.

Our directional amplifier headset improves speech listening when you find yourself a few meters away from a person talking, especially if the person you are trying to listen to speaks in a low voice; the directional amplifier headset also features a special circuit to optimize listening on standard frequencies (range 200-5300Hz) as well as low (range 200-3000Hz), medium (400-5300Hz) or high (450-7000Hz) sound frequency range: each frequency band can be selected at will by the user.
Listening volume is also adjustable at will by the user, on a scale of 10 levels for a maximum 40dB of audio amplification.

Comes complete with all accessories and also in a version that can be combined with our professional miniature recorder ESTP10, in order to be able to listen and record simultaneously.

Built-in rechargeable lithium-Ion battery, operation and battery charge level control LED, maximum continuous operating time is up to a maximum of 24 hours.
