I no longer use these earphones as I purchased a different pair. I haven't used them continuously for more than two hours at a time, so I can't say for sure about the continuous playback time, but they don't run out of battery quickly. I connected them to Bluetooth using the dedicated app. Used with iPhone and iPad. Everything in the photos is included. Sold as is. - Brand: Technics EAH-AZ40 - Type: Wireless Earphones - Color: Black - Case: With charging case Thank you for looking.
