Very good value for money! The battery holds tred good! I have reloaded as 2 weeks after its first use. The size is good though a little too big but the headset will not fall! I use it mostly for sport by listening to music or watching a series (tablet / phone), I have not used the calling function, so I could not record it. I do not know if the model or so if it's only mine, but I feel it sizzles with too pronounced for some serious music. I got in promo (28th) otherwise it would not be worth its price, other headsets at the same price to see 10 more expensive will be better. That's why I put it 3 stars.
