Supersound, weak material.

Per
For me, the Ear Force PX5 is easily misused and works for quite outstanding. Usually I close him namely my Smart TV to: A free USB slot in the television feeds the base station with power, the SP / DIF output of the TV offers optimal digital sound. Of course, the surround effect lasts for DVDs, etc. within limits, but the sound quality itself is just great!
Also, the IR receiver works perfectly (in my house at least). Only when transformed or turning the sound is sometimes interrupted briefly. But the range is surprisingly large.
The apparatus looks good and is quite suitable for the living room.
Even with long-term wearing comfort can not yield.
Bluetooth: As a listening device for listening to music on a smartphone the Ear Force PX5 offers pure luxury.

Contra
As a headset in conjunction with a mobile phone he is good less, since the built-in microphone delivers a weak signal.
Nervous doing me the dull, barely intelligible voice of the American "announcer", you can not turn off or replace. A selection of sound signals would be more appropriate to report the status of the device ..
It is difficult to understand that the included base unit can not be used as a charging station. As a power source for the headphone unit you have to use AA batteries or rechargeable batteries instead. This is cumbersome and drives operational costs unnecessarily high.

Conclusion
When headphones per se you will - even at a much higher price - hardly get better sound quality. Because you can take the mentioned disadvantages confidently in purchasing.

March 2015: Two stars less.
In the rather high price you would expect from the mechanical parts a certain longevity. Unfortunately, that is not the case here. The connecting portion between the headband and ear is weak - too weak obviously, to withstand stress in the long run (less than four years!). The part crashed to the ground and arched. Sa I have no other choice but to dispose of the thing. Sorry, Turtle Beach: bie again!
