@@user-nz6fe7uj7e i haven’t this brand right now ! Cause I sold it 🤗 But it’s easy you connect the cable in the adapter and other side in the case of the earbuds , and for using it with the phone : just take out the earbuds from the case , switch On the Bluetooth in you device and searching for them ..
No e usado muchos TWS pero la verdad estos por su precio son tremendos la verdad tienen buenos bajos al menos unos bajos muy decentes en serio y sobre el volumen muchos no tolerarian hasta el 100%.... A ojo cerrado recomendados
I have this product. in fact, if you want to connect this on the iPhone, you should select SDD power less than 4.5W or cannot useful. But even though that still connect external power to use.
