Hi Laurent, hope all is well! You have to check out William Hernandez creation the "Obbastudio". I own a set of the "Obbastudio", and let me tell you they are very nice. The "Obbas" reduce the sound of the instrument to a 90%, so you can practice anytime without disturbing your neighbors, plus practicing in wood will strengthen your hands and will clean your sounds. William Hernandez is a good friend of Orlando Poleo. Check out his web site at:

Hope this helps!
