By cons, produces too BIG in the ears, not at all discreet, sound settings buttons (+ and -) or passing tracks (same keys) not easily accessible once the product is placed in the ears, the headphones take difficulty in the ears, poor quality plastic (Asian product). Amazon Announces crossed out price of € 40 at the base, then a final price of 20, but a product import from Asian (site also translated into French), we find this product to less than 15 euros, including postage !
This product is not worth the advertised price ,.
I would not recommend this product!
