I bought a DELL BYTE CORSECA DM5710BT headset. I am able to pair it with my Lenovo S720 phone. But the connection status is shown in Bluetooth menu as "Connected(no media)".

When i click the multifunction button of headset, music starts to play via phone's inbuilt speaker. I am not geting audio out through the headset.

Same problem in with my DELL laptop (XPS 15R). Headset gets paired/connected. But audio output will still be through laptop speakers.

Please help me out, so that I can replace the product if find defective.
