Three, rambler lollipop pod Pro(329)

Rambler lollipop Pro adds active noise reduction function on the basis of Rambler lollipop, and adopts mixed dual active noise reduction technology, and the noise reduction depth reaches 38dB. Rambler lollipop Pro also uses environmental sound monitoring to reduce noise, and with the use of APP, it can independently adjust the environmental sound. From the sense of experience, the function of environmental sound monitoring is not very timely. Although the mobile APP can be adjusted by itself, it is inconvenient to adjust it by itself every time.

Rambler lollipop Pro is equipped with polymer composite diaphragm, which has clear sound quality, but it is slightly insufficient in bass performance and the bass output is not very powerful.
