Indeed this headset works rather well but it does not isolate that well I think they could have done better.
On the other hand very easy to use, the Bluetooth connection it done quickly.
A chouilla over Lower would have been perfect.
Good battery life, the day is largely due (transportation to the morning in the office, in the office after noon and return in the transport) battery holds well.
The buttons are rather practice a little bigger would have.
However a negative point when we stop music means a little noise in the headphones a bit like parasites. Noise that we hear more once we put sound.
So here as I say in the title "Okay overall".
Phillips thank you for this and thank you Amazon for its quality of service always on top!
