The Tempo setting range is a generous 30--252 BPM, and a wide variety of beats and rhythms are provided. In spite of its ultra-small sized body, the in-ear metronome provides approximately 200 hours of continuous operation using a coin-type Lithium battery. The in-ear metronome also includes a well-cushioned ear pad and a carrying case that neatly stores The in-ear metronome.
