With these Bluetooth headphones, I'm not disappointed. They are lightweight, integrated remote control can change songs, daugmenter or decrease the volume and turn them on or off.
The sound quality is not excellent but quite drinkable, and in any case I do not see myself wandering around the streets with my helmet Marshall (the only one with an almost perfect).
For the use in running, these headphones can be a good solution. Note however that the remote control will tend to shake a little in all directions and that could be embarrassing.
A user guide is provided, but for my i phone pairing is done automatically. Finally, note that they are supplied with 3 small rubber in different sizes to fit better to the shape of your ear.
I suggest these headphones to all, and especially to those who listen to music in public transport.
