The GM-1 is an ultra-compact metronome that you can attach to one ear just like a handset. When you use multiple GM-1 devices, everyone will hear the same, so everyone can train in sync at the same pace. Therefore, GM-1 can be used to rehearse groups such as marching bands or dance groups, or for rehearsals where you need to move. The channel-type earring unit sits comfortably and safely on your ear, and thanks to it, you can clearly hear the sound of the metronome in the surrounding noise.

The GM-1 is ideal for achieving that perfect moment when everyone fully feels the right pace and rhythm, so all teammates and colleagues remain in sync throughout the performance.
