II just plug a small box that will go unnoticed (7cm / 7cm) on the source (tv, computer ..) anything with a headphone output.
His helmet is loaded (same charger as a phone or notebook computer) very simple and fast ...
And we light the whole and voila! Efficiency and Simplicity 1 min top chrono!
and Sound ... say is that Sony Sound. I'm not an expert but from my experience this is one of the best "sound" headphones I could hear.
Small least: It has an advantage its lightness, so that you can keep it on the ears without overheat BUT after a while we will have to stop and remove. It does not keep hours like headphones 300/400 sure. In this case I advise TOP TOP Sony MDR-HW700DS!
Another disadvantage resulting from the advantage of being light, it seems fragile. It will take care of it. That's a lot of ... Plastic TOO. In my opinion and I will not do the test ;-), one little break in one hand!
Honestly I recommend 99% for this wireless headset.
First by what you what you buy: wireless with good sound that works perfectly.
Although the plastic design is pretty!
and especially the price factor, now with 20% discount less than 100 Sony This is crazy !!
