The plastic material Outdoor is not one of the millions is very plasticoso but all in all it works quite well, but it is not exactly the bone conduction that one would expect you feel a small chest within that plays all sounds, Don't be very discrete with this type of earphones because who there siedas alongside can listen to whatever that is played in earphone.

Everything works, the quality suits.

Everything works fine Goods arrived, all is well

received as described but they are not very reliable and I'm not satisfied with the quality and connection reliability is very poor, I do not recommend this product. In saying that they are very cheap.

Good seller
