Positive: As usual, Received quickly. Quality packaging.
Negative: The first headphone does not have a max volume control system as mentioned in the statement. I consulted the model to Philips and I confirm that it is not present .... infringement ???? I dare not open the 2nd box. Foam pad a little late for sustainability.
Thank you to tell me if Amazon an open box can be returned (I will also open the second).
