Don't be fooled by the name: the Supreme Basic offers excellent features in a practical, cost-efficient model. Designed for shooting environments, the unit features 1:1 sound reproduction and separate shielded microphones to provide optimum stereo effect and location of sound direction. The model provides around 150 hours battery life with two standard AAA batteries. The AUX input means it can be connected to external audio sources, such as radios, dog-tracking devices and mp3 players.
