After being used for three days, the headphones, when turned on, were unable to establish a connection with the phone. The phone recognizes the person, but it is unable to connect with them. It was impossible to turn the headphones off; there was no reaction when the button was pressed for an extended period of time. The blue diode on the headphones was illuminated (it should have been blinking). After thirty minutes of charging, I disconnected it from the charger and, shortly thereafter, the lights went out. After I turned it on, everything functioned as it should have. The following day, I returned it to the store where I had purchased it.
