Only individually good!

The headset is very good, as long as you only have one of them in the household.
If you plan to use two or even more of these headphones simultaneously, then these are the wrong people for you! With another family member to use another pair of the same goes for the following reason: The headphones Send all on the same frequency and interfere with each other to total failure!
The Philips customer service knows this, but is unable to take back these bad design. The customer service is recommended to buy ANALOG headphones that would not mutually get in the way.
Conclusion: I have 2 new headphones that I can not use at the same time and may not return (they are not so broken).
My recommendation: If you want to use more than just a headset at the same time, do not buy from Philips. They're not ready with the technology.
