Let me talk about the overall sense of hearing first, and then I will share with you in detail the usage scenarios and sound differences of different modes.

After getting used to using TWS headphones and a single smart speaker, the first feeling of hearing the sound of Cleer Crescent is shock. The layering of high, middle and low frequencies is very obvious, and any subtle changes in sound can be heard; the degree of separation between human voice and music is very high.
