Everything is in the text, this headset is a true success from Sony. I dreamed, Sony did it ... !!! Quality material, very sober helmet is found to be very functional design and as always with Sony. Just 150 grams, once worn, one feels not at all. It is very comfortable and after two hours of gaming session, any discomfort is felt. Helmet fully compatible for movies, music and games on my "PS Vita" on my "iPhone 4" on my "iPad" and my "PC" connection without difficulty. The sound is smooth without any breath, the bass is really good and the sound is picked up to 15m without hindrance. With a PS3 that does not support bluetooth headphones, at least for her outside the chat, I had to provide myself with a Bluetooth transmitter "BlueSense TRM" (available on amazon) I plugged in my amp " Yamaha RX-V471 "that manages all my devices at home. Launch of "Avengers" in bluray on my PS3, sending the helmet powerful sound and sharp, too see, the highs are a little too present but this gene in any case listening (of course it should not put the sound bottom at the risk of saturating the helmet but this is still powerful enough). Completely filled with this helmet, audiophiles will always find something to say about the sound made but if you're like me and you are looking for a very good headset compatible with all devices for a more than reasonable price, please, it is for you.
