In my case (purchased about 2 years ago), the package included a USB cable for charging as well as an aux cable. The brochure linked to the product here also mentions a "detachable 3.5 mm headphone cable (1.3 m)". If I were you, I would ask.

No, there was no cable included. It's a wireless headset that connects via a USB-A dongle. I don't think it is intended to connect a mobile phone to it.
