What should I do if the sound of Shanling Bluetooth headset mtw300 is very small?

The outer packaging continues the compact and simple style of MTW 100. In addition, the unique diamond-shaped charging box appearance has been retained, but the material and color matching have changed greatly. The shell is made of zinc alloy, which is not only more durable through NCVM vacuum electroplating process, but also has a dark gray matte design.

Different from the metal material of the charging box, the earphone is made of ultra-light resin, and its weight is similar to that of a piece of A4 paper. With skin-friendly silicone earphone sets (7 sets of earphone sets with S/M/L models, easy to replace), there is no sense of oppression and ear loss when worn for a long time. Lightweight design also fits the ear canal better, effectively isolating external noise and creating a quiet music space.
