"COTSUBU" is the successor to the "TWS03R," which has been a long-time hit since its launch in December 2019, and is lighter and more compact, with a significant upgrade from basic performance to usability.

High-quality sound by Final Audio
"COTSUBU’s" high frequency range caused by Bluetooth® is slightly corrected with the equaliser. With such technical backing, we have achieved both powerful bass and clear vocals, and realised a relaxed and natural sound quality that makes you want to listen to it every day.

Auto pairing function
The charging case is thin and compact, so it can be easily opened and closed with one hand. In addition, it is equipped with an "auto pairing function" that starts pairing just by opening the lid of the charging case. You can listen to music as soon as you put it on your ear. Also, when the main body is stored in the charging case and the lid is closed, the power is automatically turned off, so you can rest assured that you will not forget to turn off the power.

One ear mode function
Simply return one earphone to the case and it will automatically switch to "one ear mode" without the interruption of music. In "one ear mode", stereo playback is switched to monaural playback, so you will not feel any discomfort when enjoying music with one ear. This is useful when you want to enjoy music without shutting out external sounds.

Stable connection performance with Qualcomm® QCC3040
In addition to SBC and AAC codecs, it also supports aptX ™, which has high sound quality and is not interrupted. Compatible with a wide range of iPhone and Android models, pairing is easy. In addition, it is compatible with the independent transmission technology "Qualcomm🄬 True Wireless ™ Mirroring" that automatically switches between the master unit and the child unit on the earphone side to demonstrate more stable connection performance.

Comfortable call performance with high-performance MEMS microphone
The main unit is equipped with a high-performance MEMS microphone and Qualcomm® cVc ™ noise cancelling function, which eliminates ambient noise and delivers clear voice to the other party. In addition, the natural sound quality that makes listening less tiring allows you to hear the other party's voice firmly even during long meetings during teleworking.
