In all honesty, I can not remember how many years ago I purchased them. I wish they had some extra letters especially the vowels. Now the one issue I had to tackle, the range. Il suono risulta ben bilanciato nonostante si presentino come cuffie da Dj. I have short fat and wide feet, so it is hard to find slippers that fit. This product uses a lot of steel and feel very solid. Das Case ist sehr klein und hält die InEars magnetisch fest. I can’t recommend this item enough. Its very solid. This happened twice to me.
