Bluetooth mouse lags and disconnects when bluetooth headphones are connected

Setup : Macbook Pro 15 retina with touch bar. Mac Os Sierra 10.12.6

Mouse : Mx Master Logitech

Headphone : Plantronic BackBeat Go

When only the mouse is connected it works perfectly

When i connect the headphones , soom after the mouse starts to lag and soon after i loose connectivity.

Did all steps from this forum but it didn't help . Any other solutions ? It's disappointing to have such an expensive laptop and can't do this basic thing.
