About the productJapanese

COTSUBU is a completely wireless earphone that has everything: sound, connection, and ease of use. It is the successor to the TWS03R, which has been a long-selling hit since its release in December 2019, and is now lighter and more compact, with a significant upgrade in basic performance and usability. The lineup includes seven color variations, including two standard colors and five new colors, and both the main unit and the charging case are the smallest and lightest in the series. The new ultra-small body that supports touch operation fits comfortably in any ear canal. New features include an "auto pairing function" that starts pairing just by opening the charging case, and a "one-ear mode" that automatically switches by simply returning one side of the earphone to the charging case. The connection performance is equipped with a Qualcomm(R)QCC3040 chip, which achieves stable connection performance. And the sound quality is high-quality specifications supervised by the audio brand final. In addition, it is equipped with a high-performance MEMS microphone that removes surrounding noise and delivers clear sound to the other party. In addition, the natural sound quality that is easy to listen to is easy to hear, so you can hear the other party's voice clearly even during long meetings during telework.
