Aesthetic level even if the volume control is not the same one remains in the same idea Apple. Finally they are also pleasing to the ear than the originals.
In technical terms the volume controller works perfectly for pause (1 click), skip to the next song (2 clicks), and to return to the previous song (3 clicks). Nevertheless, the volume control does not change the volume and it's annoying because that's what that is used most commonly.
In conclusion, despite the name of the operating volume control in its totality it remains a product I recommend for its price and its design is significantly closer to the original model.
