The charge is enough for a day of work. If you are discharged, you can charge for an hour of work in 5-10 minutes. If there is no charging, you can connect via audio cable. You cannot charge and use at the same time. I did not notice any difference in sound through bluetooth and cable. With its pros. Price-quality ratio. Pleasant sound, at least for a non-musician. Stable reception without stuttering, including at the other end of the apartment. Good sound insulation, you can work in a rather noisy place. They sit comfortably. Add up. Sensor volume control. Possibility to connect via audio cable. Cons: Sometimes the connection is suddenly lost, you need to turn the headphones on and off and it is restored. Bass is lacking for my taste. The microphone is not the best. There are no problems with calls, I can hear normally, but the quality is not the best.
