Korg Metronome, in-ear, GM-1, black, set of 4

The GM-1 is an ultra-compact metronome that is worn like a traditional earbud. When using multiple GM-1 units, the sync function ensures perfect tempo alignment. This makes the GM-1 particularly suitable for rehearsals of marching bands, dance groups, and ensembles where participants need to move. The earbud adapts to the ear canal and fits securely. This way, you can hear the metronome signal clearly and distinctly even in a loud environment. With the GM-1, ensure that all participants are perfectly synchronized at all times and inspired accordingly.
