There is a long time since the audiophile that I am, was not impressed with his Christmas present. I had a first BT headset gaining experience at Logitech in 2004, catastrophic after 3 service returns, claim. The 3.0 by Sony that's another world is developed. This helmet is of great achievement, relatively lightweight, comfortable to wear on your head, a little less break on the neck, and easily appairable with my windows phone: finally a freed helmet of the Apple brand. Small problem: the NFC device only works with Android devices, and 1 RBT manages only one device at a time. Its level, a must, bluffing for balance, much less Basseux many other helmets, treble clearly claim their place in these earphones that isolate you almost perfectly of ambient noise. Poor quality files playback Caution: Do give that quality native CDs, even converted to 3 pm, or such FLAC formats. You'll rediscover your CD collection nuggets. A beautiful toy, which came back at 200 after 20% refund of the price by Sony -Provides limmitée in the time-or much cheaper than a Parrot Zik, completely subservient to the i-phone.
