The charging terminal is on the right handset side, but it is exposed to the outside. And a rubber waterproof cap? There is the same thing, but you have to cover it when it rains. The call quality is below expectations. I bought it because my original earphone was broken, but I'm trying to find another one.

I use it while working out and it's really good. But what if the sound is low?

It seems to be of good use for the cheap price.
