The SyncDancing Synchronized Dance Music Player from Korg is an ultra-small music player that fits directly in your ear, and provides a timing reference for ballroom dancing practice. The metronome offers a variety of beat and rhythm variations with full custom functionality. In addition to the metronome, the SyncDancing offers 20 built-in standard ballroom dance songs, which allow you to practice at any time, thereby improving your dancing skills and timing while sharpening your sense of rhythm. Practice by yourself, or synchronize the tempo via infrared so that two people can each wear a unit and practice together.

Tempo can be adjusted smoothly from 30 to 252 BPM using the jog switch, while the proprietary holding mechanism ensures the device remains firmly planted in your ear. A wide variety of beats and rhythms are provided with a beat range of 0-9, and users have the ability to choose rhythms from quarter notes, duplets, triplets, triplets with inner beat omitted, triplets with the third beat omitted, quadruplets with the middle beats omitted, and quadruplets with the third and fourth beats omitted. The unit utilizes an included coin-type lithium battery, which provides approximately 5 hours of continuous operation. The SyncDancing ships with an earpad and a carrying case.
