Amazingly easy is this headset. Comes with two different sized earbuds, two different ear hooks and two different sized stabilizers that improve the fit in the ear. The unit fits even my wife, who has very small ears when it endows each with the smaller variant. It sits surprisingly stable and also holds stronger movements (such as running or playing sports in general) was good. The design is quite appealing. The sound quality is satisfactory, but no one expects at such a small device, the fulfillment of HiFi standards. Pairing with various smartphones (Samsung, Sony) work right away and smoothly. This headset can be paired with up to six different devices.
Charged is, as usual, with a micro-USB cable. The actual cable is, the plug does not. Recharging is quick, something takes between one and two hours. The battery life is sufficient to come up with an extensive use (listening to music, phone calls) over a work or travel.
Enclosed is a small bag in which the headset, as well as the replacement or variant parts can be stowed. This is often lacking in similar models. I think that's practical. Full buy recommendation on my part.
