The previous model has been significantly updated from up to about 40 hours of playback, and it can provide up to 57 hours of wireless playback. No need to worry about running out of charge often, whether you are commuting to work or school, online classes, or for long time calls.
In addition, it supports a rapid charging function that can be used continuously for 3 hours on a 5 minute charge. You can use it safely even in sudden situations such as forgetting to charge when you don't have time.
In addition, this model also supports volume limiter function that prevents the volume from exceeding 85 dB from the app, so you can adjust it without strain on your hearing, even when using it for a long time.
