First of all I was impressed by the Phillips headphones. Deep bass and brilliant highs. But as I had connected him only to my Ipad. When I moved to my computer, this has suddenly disconnected from the WLAN. When I was then reconnected after several attempts with my router, the Internet speed has diminished. Then the headset has alternately switched off one side and turned on again, which does not change until now. After testing bellyful I have him now unfortunately return because he has too much interference with my wireless. Since this is not retained in the product description, there is of me only 1 star.
