Sennheiser HD 4.30G [Android Remote]
Cable
This headphone does not have Bluetooth as listed in the specifications. "Remote" means that you can send certain commands to the Android or iOS phone via the buttons in the control unit in the cable. See the last picture of the product.
I hope I am not right, but I have not come across any headphones with Bluetooth and cable.
