pros 1 i wont talk abt bass cz its amazing really thumping bass 2 backup is good lasts nearly 12hrs for me 3 design and build quality okay but not great it should be better 4 headset will turn off automatically after 10m after disconnecting from bluetooth only 5 additional plus point is wired jack useful when battery dies cons 1 biggest con is cushions are not comfortable at all to me and ears get lot of paining after 10m of listen for me i dont hw other feels
