The only reason why I?m giving a 4/5 is the bulky design it?s HUGE I have small ears and these cover half my face lol That is literally my only issue sound quality is amazing surround sound as promise definitely gives a immersed experience. Believe it or not, it is impossible to find slippers that are good quality, simple, basic and yet feminine ( and open toe! With 6 DPI options you kind of lose track of which one you are on and spend too much time having to figure it out. I would very much recommend these sandals to anyone! Our house is ?awash? with wireless signals and fluorescents so I don?t have a pristine noise free environment. I do this for most all athletic shoes actually). I thought I was getting a real good deal on the product this time but was surprised to find you now have to take 4 a day instead of 2 a day. I ordered two mats; one of them is dull and the other is exceedingly dull. The left shoe a little better. They are so.
