It's been a while since I wanted a mini branded wireless headset at a not too expensive price. Finally, I found: this is the SONY SBH20 which corresponds exactly to my "book" specifications. soon unwrapped (no more than 5 minutes), there is a charger in the package, the cable for the charger, a small bag with 2 extra sets of earphones, mini helmet with his catch to standard mini headphone and finally the small housing (3 cm square) bluetooth. As already loaded, I lai fabranché synchronize with 3 devices: tablet and mobile phone Samsung and Asus laptop gamer. For each, barely a minute and it was the top !!!! Question listening, this is good. For those wanting a more this or that, any headphones or even portable speaker can be connected (with a mini headphone jack) on the Sony housing and provide the sound of which is connected. The helmet, supplied by Sony, is very suitable. The scope of this bluetooth housing is about 10 meters (perfect for listening in an apartment) so that you can leave, for example, his cell phone in a room and listen to a piece of music on Deezer while being able to change tracks with the controls of the housing and also having a telephone communication since the housing is provided with a microphone. My wife, having been seduced by this helmet, made me a commissioned a second !!!! In two words: excellence by Sony
