Which is better, rambler tws 1 or tws2?

TWS 1 is not much different from tws2, but TWS2 is a new product just released, and its sound quality has been improved. I suggest starting with this. I have just been in into the pit for some time, so let's talk about my experience. The sound effect is good and the bass is very heavy.

Appearance material: fashionable and light to wear: comfortable endurance: just took it out for more than two hours. Other features: generally good, it is the earphone I want, and the sound is clear.

The sound quality is also very good. I will continue to pay attention and be satisfied.
