The product is not all light - the light of its size - which is a good sign. It is not too heavy either, not tendinitis required: D The material is pleasant to the touch, rubber and so allows the speaker to remain stable and above all not to slip on different coatings. This also improves the grip, there was little risk of breaking down.
The buttons are represented by engravings in the material on the product side: Power on / off, bluetooth association, vol-, vol +; it's simple, convenient and intuitive, the manual has little reason to be. Tested in combination with an Android smartphone, the Bluetooth communication is fast and simple. The battery life is decent, watch 5 hours are theoretical, difficult to atteindre.La Charging is via USB only.
The sound is a surprise for such a compact product, the power that comes out is amazing and we even managed to have midbass gently. After so do not expect a speaker of this style Dantesque performance, but I think for what is expected in it is fine. The voices are perfectly clear and distinct, the development that is at the level of the medium and low-pitched; which perfectly matches what is expected as stamp in the sometimes diverse and varied situations plays.
The plus is a very small business, resealable strap that can hang in different locations or carry it by hand easily.
A good product / performance ratio excellent price. A good surprise.
